– Who knows the REF stability procedure? Both the voltage injecting method And the current injecting method? – When you create in the zone or out zone fault for REF stability there will always be a flow of current. – Short Primary Bushing Phase R S T with secondary terminal shorted after CT. Then Inject One Phase Voltage, Then Current will flow through the Primary bushing and NHV. Inject current from low voltage side, in R phase and check for current (secondary current and display current in relay) at high voltage side. Pl inject current outside the REF CT covering zones – relay should be stable (should not trip)
Reverse the R phase secondary terminals at TB(HV side) and take measurements ( display and secondary) – What about lv side y,b phases? should be short or kept open? – Open. – Repeat for the Y and B phases. Then for R, Y B combined. – Note that NGR must be shorted Or it would be burned. – What if it’s a Delta star transformer? – HV and LV CTs must-read values to short and reverse secondaries at TB. – How to test REF on the Delta side if it’s available with an earthing transformer? – I think this is the connection but I don’t know why we short ckt on the delta side two phases? – Because a single phase-to-earth fault on the star side will get reflected as a phase-to-phase fault on the delta side? – Is this shorting mandatory for star Transformers also? – what if short all the primary phases? – It’s only if we inject three phases, Current will also loop. we stability 3 phase then REF
– Creating the fault within zones – you can do this by closing Earth switches (outside the CT zones). Creating the virtual Earth fault through closing the earth switches (outside the REF CT zones).
– Do anyone knows how to do the AVR auto mode test on ABB RET670. The issue is over current blocking feedback that need to be recorded through goose with Omicron kit? – Anyone can share the ABB REJ601 relay password to edit setting parameters – Can we set CT ratio 650/1 in ABB REJ601 – Is there any option for the TCS circuit at Siemens SIPROTEC5 BCU 6MD – it is urgent if anyone has information please share it.
– I found some mismatch between PCM and IED technical Key, Does anyone here know how to fix this? – If you have the right connectivity package concerning the IED software version, then create the bay from scratch and collect. Normally it detects it automatically
– Does anyone have a Methodology for End to End Pilot wire differential protection for the cable? Please share Thanks in advance. – You have to download it from the SEL website
– Can anyone tell me about the MIF II digital feeder relay GE Overload thermal relay setting detail of cooling time and heating time? model no GEK-106237Q
– Does anyone have Schneider electric relay SEPAM T82 RELAY technical catalog? – You can download it from www.Schneider-electric.com.
– Which parameter (Measured or Derived) does the relay sense to trip the relay if the IN exceeds the setting? IN Measured or IN Derived? – Check the Analog card whether a separate coil is provided for neutral. Protection engineer user x: Which relay? – It depends upon which factor you are using in settings. – What is the issue? When I’m going to install PCM 600 v2.10 then this error will come. – Which SQL Server is needed for PCM 600 v2.10? – That’s telling 2014 express.
Protection engineer user x: Guys, If anyone has IEC 60870-5 – 101 & IEC 60870-5 – 104, then please send… Protection user x: Is there any one user of the DEIF Controller? Protection engineer user x: Anyone has an idea of IoS A & IREF N in ABB REF relays? Protection engineer user x: IOS A & IREF N. Protection user x:
– Why do we put an OLTC of the generator in local mode? – Are you talking about the OLTC of Trs at Generation Station? – Local it’s mean cannot access remotely, depending on operation requirements.
-We lost the password of the MicomP143 relay. Is there any option to reset the password? – You need to contact customer care with security code device details
– Does anyone know how to Synchron the date and time of relay micom from the Serial Port?
– What could be the possible cause of the increase in the current of one phase of a generator? My generator trips of overcurrent in Phase B. I have done all the checks on the generator and it seems okay.
– Is it possible to inject both 50Hz and 100Hz of two current sources in the CMC356 Kit? – Yes, parallel sources 1 and 2 and use source 1 for 50Hz and source 2 for 100Hz.
– The above method should work for checking harmonic restraint blocking and tripping percentage. In my quick CMC, if I change 100hz then remaining all sources also will get changed into 100hz for harmonics.
– Right-click and select unsync.
– Can anyone explain the function of the three CTs on the neutral side? – Possibly for generator differential protection. These CTs are connected on the main winding of Gen. However, on the neutral side of Gen and thus, referred to as neutral CT. – I was thinking if done in residual connection then it will be used for stator earth fault protection on the neutral side. But the CTs are not residually connected.
– During one phase PT failure, will overflux relay work? Has anyone seen this kind of voltage transformer connection? – Why is B-phase winding grounded on the secondary side? – Can u share the nameplate details of the PT. – yes, in an oil company, usually they only use 2 PT inputs and make it a delta connection in the relay – That’s an open delta voltage transformer or potential transformer. – It’s mainly used as an input to detect earth faults using neutral voltage displacement. – Typically the sum of the voltage across D7 and D9 is zero. however, should there be an earth fault and one of the phases hit the ground? you will get voltage across the open point. – Such schemes are used in ungrounded systems or on generator-transformer sets. there is no path for earth fault. – Sorry open wye but the scheme is the same. – Open delta connection, Yellow phase normally will ground. But as per the drawing seen some conflict. Normally 2 VT Winding we can see.
– This is a star connection with the y phase grounded Not an open delta. I was reading on the internet it’s some old practice followed in the UK.
– Anyone has any experience with diesel Genset paralleling on the common neutral resistor? How many generators can work connected to the resistor and how many can work isolated in parallel mode? That’s a very big open question. – Yes, it is problematic to solve its protection system. – Yes we typically run the neutrals to a common neutral bar. Install at least 3 the neutral earthing resistors and contactors – Are you talking about medium-voltage generators? – Yeah. – How did you calculate the size of resistors? – Please, can you share some calculations? – I need a setting guide for directional protection. – If any example for Double feed SubStation with the tiebreaker normally closed – What is the Apts scheme?
– For this system, with the two Transformers secondary breakers and the tiebreaker normally closed, and installing directional on the two secondaries, I need some guidance on how to make the setting for the directional, And if anyone has a similar case I will be glad if he shares his settings and how to make them? – the intention of the Directional on the secondary side is for backup protection? I ever encounter an application that uses the secondary side 67 as a backup by looking up into the transformer and if it operates it will trip both HV and LV.
– Can anybody share about the zig-zag transformer? Principle operation of it.
– Anyone has SR 469, SR 650, and SR 750 test formats? Which is software used for these relays? Anyone pls help?
– What could be the cause of the SF alarm? – PLC is communicating with another PLC over Profibus – Well, it can be a lot of stuff, but the first thing I always have for this alarm. SISTEM FAULT means that you may have some unit programmed inside your PLC that is not connected in the field. – So if it still works let it be – with that alarm all parameters of the slave address become red – This is not something to concern, just be sure you have a good backup of the PLC program. but if it remains, it will not let the startup of the Engine – Yes, but if it is already working, maybe is only a module programmed in the PLC but not connected in the field, but I say, I saw processes going on for Years with this SF, and nothing ever happened.
– We have a problem with the Generator Micom P343 that does not boot, please help us how to fix it, thanks – Check the ribbon resistance of HMI to relay. We have faced the same and asked Alstom then after they checked and replaced the ribbon, and fixed the issue. – Where is the ribbon? – Open the front side of the relay then there is a connecting ribbon cable u can find – This, is not Bad contact Ribbon the message is clear (Micom Booting) with Led Alarm lightning in red Fast It’s like PC booting, I think it’s a microprocessor issue. – We have faced the same problem in our reliance industries Jamnagar plant and Alstom itself give us a solution and change all the ribbons. Micom rebooting issue may be from the HMI problem/relay power card problem but if it comes even after replacing HMI look forward with manufacturers. It’s not just like pc booting issues. There is no chance of error in the relay or bugs like a microprocessor. – I might be wrong but I share what I experienced with the same problem. – Any vacancy for a Facilities Manager – How do I determine distance characteristics in the L90 GE relay? do someone has a commissioning manual for L90 relays?
– I want to know what you guys as an Electrical Department are doing to fight COVID-19 in their workplace. – 132kv circuit tripped showing R Y B phase and zone 1. And the same circuit is energized from another end at no load. Also, no fault was found on the circuit during patrolling. What will be the fault? Distance Relay type Micom P 441. It could be transient or pic up fault – Does it show any distance in zone 1? – Grid staff is not too efficient to check the fault recorder. I will go to check it tomorrow and will discuss it again – What is the status now does the line charge from both ends? – Only from another end at no load – Sir but usually these transients will be blocked by numerical relays rights – I think it may be DC grounding – Check the fault recorded to see the fault current and voltage – Lighting – Depending on the magnitude and relay Makes. We have had similar invent without any trace of a physical cause -can you share with us the Comtrade file
– What is the standard setting of the characteristic angle for directional overcurrent phase and ground (67/67N)? – does somebody has this relay technical manual ABB PCD for the recloser?
– Hi anyone has a static VAR compensator (SVC) protection scheme that can share? – What is the standard setting of the characteristic angle for directional overcurrent phase and ground (67/67N)? – For typical distribution networks (up to 33 kV), I set it to 30 degrees. For sub-transmission/transmission, I set it to 45 degrees, between the current phase and voltage polarizing quantity. – However different scenarios may require different angles and have to be worked out. – This angle for directional phase overcurrent? What about the angle for directional ground over_\]\]\]]]\\]]\current 67N? – Are there any references for how to make the setting for directional phase and ground overcurrent 67/67N? – I would typically read the relay manual, And use the default recommended value. The actual math behind setting them can be very tricky. – Which relay are you using? – Sepam s40 – The application is two parallel Transformers – What’s the voltage level and how far is the relay from the supply transformer? – From experience, RCA is 20~40 – For 67N, the value is dependent on the type of grounding. Please refer to NPAG, it was clearly explained there – Anyone has a digsi4 Activation Key? And for 67, if I am not mistaken, RCA is set based on the impedance angle of the system

– I have to change CT/VT ratio in an Elster A1800 energy meter. Already got established communication with the meter via Metercat 3.5 software. I believe CT/VT ratios can be changed via the function “Program” but I am not able to proceed as everything at the “Program” popup window is grey (not editable), I request you support me in changing the CT/VT ratios. – You have to enable changing xt ratio on the parameters function
– There is no Parameter menu in Functions? please clarify in detail or send a snapshot – Hi Guys, I have a question for the 220KV level, which is suitable for either CVT or IVT(PT)? And why Usually we are adopting IVT(PT) in Andhra Pradesh India – CVT always – Sir can you please support your statement As we have observed the drift in secondary voltages is more in CVT compared to IVT over a time span – Mainly installation reasons. they are lighter, cheaper, and Safer (transfer of emf when a fault occurs) as there is no direct connection to the primary voltage source. – Can you explain how does the voltage drift? – Deterioration in the capacitance levels throughout operations results in variations in secondary voltages Can’t that be fixed during maintenance? (Note: I don’t have any experience in maintenance and operation Even I don’t have any experience in Maintenance. But I am not sure we can improve this ineffective manner) – CVT for transmission circuits or High Voltage i.e greater than 66kV and IVT for distribution circuits 33kV and below – Moreover, we are mostly using IVT in 220KV levels also so, I am not aware of fixing methods. I believe it’s a cost trade-off. In India IVTs in 220kV class are more affordable than CVTs. And yet you may see them actively used in 220kV stations where the transmission system is at 220kV level. This is because the same CVT would be used as a coupling capacitor for PLCC communications as well. – That’s my understanding – Why when we calculate short circuits at transformer secondary we should consider no-load ph to phase voltage not rated voltage?! – Yes.CVT is more affordable to be used since the consideration of its(equipment) isolation to H.V. – Yes, we can track and analyze its dissipation factor( Tan Delta measurement) – Which position? – This is an AVR relay from ZIV bringing. -anyone has the pin configuration of this relay? – If you mean bias setting, then I would say it has to be calculated based on the transformer parameters – Hello everybody, good morning.

– We need to do an 87L test, as you can see in the secondary current to relay is very low 0.044A. We did a second injection for the GE L90 relay and found it doesn’t read 0.044A. Value is fluctuating and gets stable at 0.1A.
– why the 51N protection of the REF615A relay operates in an almost constant time of 0.06 seconds – reviewing the operation curve the minimum operation time is 0.02 seconds at least the first 3 tests would have given me the correct value – check the other seating. Check the type of curve selected in the relay, Whether it is time or IDMT -1 group setting might be clashing with another one, check all stage settings group-wise. – Work Is for Automation Visit in Kolkata. Just visit the site in Kolkata only people from Kolkata plz contact me.

– I have a problem with Micom P443 for Distance Protection. I have a problem with System Checks for Autoreclose, anyone can tell me what is the difference between CS1 Close Enable dan C/S AR Immediate? – Cs1 close enable is the setting of sync check on which you want to recloser the circuit breaker like on Live Line Live Bus or Live bus Dead Line or Dead Bus. – If you enable c/s AR immediate then it means that if during the dead time system check conditions are met then it will reclose the breaker without waiting for the remaining dead time period, – Like for example if dead time is 1 sec – And system check conditions are met during 0.6 seconds of dead time, then the relay will give reclose command without waiting for the remaining 0.4seconds of dead time. But you have disabled the system check conditions on shot1 which means it will reclose the breaker without looking into any system check conditions, – Sys check on shot 1 should be enabled too.
– Hi Guys I have a question: what is the problem with a 3phases motor run by A frequency driver, if I want to run it very slowly for instance at 4HZ normally it runs at a modulated Frequency variable between 50Hz and 0 but what happens to a very low frequency? – I know that it will run slow, but it will warm up a lot right? but more than that what will it happen? somebody, some documentation to explain this phenomenon? – It depends on the loading. The higher its loading, the more power is needed to turn the output torque. If you don’t have a load, just make sure your lower frequency setting has a minimal current to move the rotor otherwise, it will overheat. – I even reinstalled my windows not going, I checked the internet settings also.

– Anybody can please share with ME Schneider Software SFT SAV? – what does this number means 6000 of this RCD? – It can open currents up to 6000A. 6kA – Note it’s RCBO not RCD – What s the difference? Because some tell me it is the max number of trips. RCBO stands for residual current circuit breaker. It can open faults up to 6000A. It can be used for short circuit protection as well as sensitive faults of 30ma. RCD is a residual current device. It’s used only to pick up sensitive 30ma faults. They can’t open full short-circuit currents. -Think of RCBO as RCD+MCB – No it’s the rated fault level.

Simultaneously inject a small current to monitor the device voltage ports are also not working – How about the current ports? -They are also not working – Make sure when you start the device the knob selector is in an off position. – Check the fuses too
– Does anyone know if you can force or simulate voltage on an ABB relay? That is, without using a device like Omicron – someone helps, how can I test the GE L90 diff relay as a stand-alone without connecting with another one? You can only force digital outputs and simulate inputs. You can’t force analog signals such as voltage and currents. You need an external source – I’ve never dealt with this relay but If it is for line differential, chances are that you’ll need two relays. the receiver and transmitter – But you can still use the primary injection method to do the testing – Do you have to test line differential? – You can go to setting, testing, channel test, and loopback. Inject currents, the relay will consider one current as local and one as remote

– does somebody here have some “how to configure Modbus protocol in SEL relays” document or some kind like that? – Someone has a method statement for Testing CVT Tan Delta
-Does anybody have a project for the RED670 relay? – Anything, in particular, you are after !’vv? – Current line differential relays fairly straightforward?
– Anyone knows what is the problem when a source (power plant) transmits power to a substation, then the neutral current monitored in the power meter is a bit higher than normal? – I know that It means that there is an unbalance current in each phase. But what else can be that causes the phenomenon? – The P.F on phases R and S are lagging 0.9, but phase T shows a leading P.F.
– In case it’s an internal fault, just assume that the 87 T relay and Ref relay will trip. – your understanding is correct. But apart from it, if primary Overcurrent (50/51P) works, it will trip the CB 150 kV, and how about the CB 20 kV? – Is it required to trip the CB 20 kV too? – 87T trip, REF not really, depending on the fault. PP fault or 3P internal fault won’t initiate REF – To isolate the power from the LV side too, in case of bus section on the 20 kV side is closed – Depends on the control scheme we use in most of the cases we adopt if HV side CB trips on protection LV CB also gets a trip, and REF is more sensitive for earth faults in the differential zone. If it is an earth fault REF trips faster than Diff. – I think that 20 kV CB will need to trip too to prevent reverse power from the remanent voltage (power) at Bus 20 kV side. But if there is a remanent voltage on the 20 kV side, is it possible to induce a voltage in the primary winding to create a current? – Since you have NGR, an earth fault close to neutral may not be detected by REF. – Percentage of the unprotected zone can be calculated based on relay settings and CT ratio. – Yes. due to the resistance, the sensitivity will be limited. – Have everyone ever tried the induced voltage on the secondary winding of step down Transformer i.e. let’s say 150/33 kV. How about the primary winding transformer, does it will generate a low current or a harmonic current? – Actually, fault moves towards the source. In actual LV will not trip because the fault current will move towards the source side (150kv) side but if inter trip function is available then LV 20kv side will trip too – Anyone knows about the calculation to get the value of Z1 Sensit? Iph>1 ? – Fault current should be above this value to identify zone 1 or zone 2 faults – I got it. But how to get this value? – Okay. I have found it was 1.2 x CCC / CT Ratio – CCC indicates which value? please clarify I doubt the Current Carrying Capacity Of the conductor – In Distance Relay – Anyone knows the CB IS( In-Service) Time function? – Since I close my CB then the IS time starts to count to set AR Block – If CB is manually closed then after this time CB will be considered in service and the Auto Recloser function will be enabled too. – But why it AR block indication appear? – After the CB IS Time starts to count. Still struggling on this distance relay – Because during CB IS time AR Function is disabled to block the AR on SOTF fault, change to ABB REL670 – What type of relay is this one? – P443 Micom – does anybody here has a p14d Modbus register – who knows the ZIV default password – Any ZIV relays specialist – Hello all, does anyone has a GRL 200 Toshiba Line Current Diff Manual Book? – Four corner numbers 7931

– May I know if would there be an issue if we use a CT with a high Burden (15VA for example) for a protection relay (microprocessor type). For the old mechanical type, I understand that the CT needs a higher burden to drive the armature – when I turn on the generator in this panel my generator has an unstable frequency but when I operate it manually the frequency stabilizes. what may be the cause of this? – Is your gen-set in synch with other gen? – no sir. What is voltage? – plz check the gain & another setting for your operator panel – 460v – there is no problem with the engine & gen-set itself it is the only problem with the operator panel feedback signal which will be generated as per setting – Cause freq regulation is in the generator itself not in Woodward – we try to bleed fuel on the generator. but nothing happened – I thought Woodward only does parallel synchronization and some protection functions but is only using small loads that’s why we don’t sync our generators. – I looked at the manual for easygen. There is a function of frequency control. I have the same system – But never got time to check every function in Woodward. – I do check some functions but the configuration has a password. the management told me that the supplier has the access to its unit.

If a reader does not resolve this try to see if there is a new version of PCM. – 132kV transformer HV breaker was closed on NO load and the LV breaker was open, but suddenly differential relay operates and gives a differential trip. In the fault study, the HV side current was 860 Amp. Somebody tell me what could be the reason? – For how much time the transformer was on no load? 132/11.5kV? -Approximately 10 to 15 minutes – MVA? -132/22 kV (wind power plant) – There must b some issue, – So this is not inrush – Do TTR and winding resistance, – If it is the newly commissioned plant then the issue will be in the relay setting otherwise check transformer winding. do the IR. – I did an excitation test @ 10 kV and the results were OK. – Plant is in operation for the last 4 years. You will have to do TTR and winding resistance to diagnose the matter, Hope you will get the problem by doing these tests,
– Any mechanical protection PRD, BUCH has operated. Did u retrieve the fault records from the relay? – TTR? – turns ratio test – No trip from mechanical protection. – In the fault record HV current was 860Amp and LV current was 0 amp. – Check the CT ratio adopted in the differential relay and what was the differential current setting adopted and actual current during the relay operation? – Transformer turns ratio
– 860AMP WAS A SINGLE PHASE OR TWO PHASES OR IN 3 PHASES? – In 3 phase – Did you check the lighting arrester AT 132 KV SIDE? – Yes surge arrestor can also be damaged or weakened, as you are using Yard CT for Differential protection – do also check your HV arrestors
– Can anyone help me with the PACiS configurator? – Physically that was OK, for counter I will check – Do hipot test of arrestors, which might be differential tripped because of arrestors, If u have a secondary injection kit like Omron or Freja plz do the secondary injection to know that there is no problem from the relay side. – can I ask why my plc doesn’t read flow? – Check that the analog signal is reaching from your flow meter to plc? – Check 4 to 20 amp signal

Fault current level 50 MVA transformer installed at state electricity board substation and we are consumers with 33 kv feeder voltage – 50MVA 220/33 KV star/ star connected transformer 11% impedance – Is the ct used only for over current and earth fault? – Yes 50,51, 50G, 51G – Strictly speaking, I would put 200/1 5P40 2.5 VA. However, if the relays have CT saturation detection, you could go lower. – What’s the relay being used? – P127 – Do you have the CT test results? In particular the DC resistance of the CT. -Can you give your consideration or calculations for this selection – So you need an accuracy limit factor of 40, with a low burden.
– you won’t need much burden as the relay is numerical and installed inside the switchgear – Your existing 50/1, 15 VA may actually work if you knew the DC resistance. – Do I have to check with the CT testing kit?? – I believe CT supplier should have this information – Yeah if you have test equipment (Omicron CR analyzer or similar) that should be easily possible – That’s possible, however normally the manufacturer will not specify the DC resistance for 5P/10P class acts. No harm in asking them though – CT’s Analyser – Ok I will check with him today, as I don’t have an omicron kit available nearby That is the only option I have
– How do you coordinate DC resistance with fault current? – So if Rct<= 1.75 ohm, you can use it For a 50/1 A ct this may be achievable. need to Replace 33 kv side CT with, 1000/1A, 5P10,15 VA With this approach, I’d reckoned to check the pickup values.
– Ynynd1 And tertiary (delta winding) are unloaded? – Then no issue transformer will follow the system phase sequence,
– What is the difference between IN-HV Deriv Angle and IN-HV Measd Angle on monitoring online? – Derived means the neutral current has been calculated by summation of IA, IB, and IC whereas measured means the neutral wire of ct secondary is connected to the neutral element of the relay, and it is being measured, – What is a dead zone in protection?? – Dead zone is the Zone between CT & Open CB. It’s the point not seen in the zone of protection that of a relay. If a fault occurs at this point, the relay will not issue a trip. Usually between CT and breaker – IN HV derive is neutral vector calculation, meanwhile In HV measured is a neutral REF winding – We cannot say it is neutral ref winding until we see the setting of the relay, – the setting of the wiring diagram is right. The relay and schematic drawing setting depict the connection of the ct secondary wires with the differential relay.

– Which power analyzer is best for Harmonic measurement? I need to measure Harmonics order’s magnitudes and phase angle. – Fluke 1735 – Fluke 434
Which power companies are using the whole IEC61850 (Sample Value, GOOSE, and MMS) in their substations? or are they just adept GOOSE and MMS only? The CT and PT are still conventional types?
– How to check this relay? – the setting is 20%
Inject the current above that value and check the trip time. Pick up and all. – How to test locked rotor in Easergy p3 g32 relay? – How do know the TMS and type of curve of this overcurrent relay? how to Calculate the time of tripping? …3-sec normal inverse curve. – TMS 0.2 – Would you please explain? – How do you get it? -100% IDMT settings. 800% instantaneous setting. – Check there I don’t know what to call them, those toggle switch which side they are selected just sum it, And multiply by the factors mentioned and you will get the setting. – For the left side instant setting 200 + (2+1) 200 = 800 % For TMS 0.12= 0.2
-The upper two are for different purposes. – Different tables are mentioned over there Just check the S 1 -8 no. And then see the upper two toggle positions. – I hope it is clear to you.
– We have two transformers (66/11.5 kV, 50/55 MVA, 600A NGR earthed on the 11.5kV side). There is two incomer-one bus coupler scheme at 11kV bus. – Due to some constraints, we are not able to get a 66 kV supply from the grid. However, 11kV direct supply is offered by the grid for no-load charging at an 11kV bus from the identical transformer on the grid side. – Please revert with technical constraints related to the subject. – Hi everyone, l hope you are well, and safe; could you share ” relay coordination and setting for substation 230/400kv(excel sheet+ explanation) thanks in advanced.
– We are facing one issue in one of the plants that we have laid 3Core 400 Sq.mm 22KV XLPE cable to provide power supply to one of the small production units. The cable length is approximately 2500Mtrs and the state electricity board has implemented KVAH billing now. So the problem is even though there are zero loads at receiving end source end meter shows 40KVAH apparent power and 40KVAR reactive power. Is it because of cable capacitance? If yes what is the solution to avoid the same?
– As KVAH billing is implemented it is directly impacting cost very heavily.
– Can experts give your valuable inputs on this. – Since it is a cable then it will be generating ” VAR”.. hence it is not possible 40 kVAH & 40 kVAR – there is a chance of a cable charging current. Once check with the leakage meter in the secondary side of metering MFM, check how much leakage current is showing. And also ensure whether c.t wiring is connected properly or not it means the metering core of c.t is to be connected to meter only and also protection core of c.t is always connected to be relaid. I think the only possibility is to charge current. – We have checked the wiring and it doesn’t have any issue. Also, we have removed the cable earthing at one end which was connected to both ends earlier. But still, the problem persists. – Check cable insulation. – Pls share the SLD with CT location.. and also cable parameters. – Is it a cable feeder or it is connected through a transformer at your end and of course power provider end power factor to be confirmed. – I think it is OK, the cable is 2.5km long, 40kVAR is 1 amp at 22kV. Who can explain why it is wrong? – Hi team, I want to know which electrical software is better to learn to come into the design side? – If anyone from the design side or if anyone knows better share the knowledge so it will be helpful to someone who doesn’t know.

What about logic programming? – WHAT IS THE WORK OF THE FOTE PANEL? – IEC 601850 – What should be done if VCB doesn’t pass contact resistance criteria? VCB should be used or not? – What should be done if VCB doesn’t pass closing time criteria? VCB should be used or not? – Fiber optic terminal equipment. This is for line communication like PLCC – No. must repair/service before put into the system – Yes digital power line carrier – What about hipot test? – hipot is passed, CB is old. – If both contact resistance and timing test fail then it is recommended to go for replacement even hipot passed. – Finally, check if any mechanical problem can be rectified. – Is this a vacuum contactor or vacuum circuit breaker? – Also, compare all 3 phases of contact resistance and timing. And all these tests can be compared with the last test results, FAT. -How old is this? – What manual says about a lifetime? With this, you can decide whether it is premature failure due to quality or any inbuilt issues, or lack of maintenance – What is the distance between ZONE 1, ZONE 2, ZONE 3? – In distance protection or busbar protection? – Distance protection -What is the means of this relay? – Carrier aided trip or communication aided trip, As per RK commission, Z1 is 80 percent of PL, Z2 is 150 percent of PL and Z3 is 120 percent of PL and Longest line. – On which mode u have set the line DTT, DUTT, PUTT, or POTT – It means that this relay is tripped based on the signal received from the far end relay.
– “How to configure RCBs and Data sets in ABB RED670 relays by referring to existing CID files? – If any kind of procedure/guidelines, please share them with me
– You must be able to upload the CID file into the IEC61850 tool and it’ll help you to configure the IED – Still, I am not clear. Can you elaborate on it? – Use the PCM600 configuration tool from abb to upload the CID file into IED. Download and install PCM600 from the ABB website – I have PCM600 V2.8 software – I have an existing PCMP project file that doesn’t have datasets and RCBs. But I have commissioned the CID file back up. Now I want to create new data set and RCBs in the PCMP Project file with help of commissioned CID file. Pls, note I am doing it for V1.1 relays. So pls check and advise me – Do we need to go for a higher CT ratio If CT secondary is not suitable for peak fault? Please share your opinion – Yes. Greater Knee point voltage CT to be chosen – you can connect two secondaries of the same CT in a series. You can use a secondary reserve, both secondaries must be equals (ratio, class,….)
– This connection is similar to installing a higher knee point CT – I have 1s1-1s2 and 2s1-2s2. How to connect both ct sec in series? Moreover these 2 secondary connections 2 different relays. In such a case how it should be connected? – I am facing a problem that after under-voltage takes place, the breaker is tripped, and after reset and normalization of voltage, I can’t able to ON the breaker. So after turning off /on the breaker control supply then I can able to turn on the breaker.

The phase angle is ok – Which relay is this..?? Line protection..?? – simple over Current and earth fault only – Can u share a pic of the relay showing phase angles while injecting a 3phase balanced current? – Relay CT terminal neutral loop wrong – Got corrected it was a mistake in setting – How to calculate CT size for motor hp please suggest me – Sizing of CT should include 120% of FLA and peak fault saturation and sub transient for dynamic half cycle
-Anyone in the group has an idea about microgrid relaying protection? – Do anyone knows about Schnider ltmr relay custom logic preparation? -No you can’t connect. Because the Current will flow on a low resistance path only. If you used 0-500 tap for R1. The same core you can’t connect R2. – You can connect two relays in serious on a single adequate tap and configure accordingly. But don’t connect two relays in parallel, as boopathi said, the current will flow on a low resistance path. If it’s a high impedance differential protection, then don’t share the CT. – And relay may malfunction due to the current magnitude flow into 2 different relays and the direction of the current subject type of protection. – Can’t we use the same tap for overcurrent and then in series for high impedance REF? Not on different taps but on different cores -In the REF phase and Neutral CTs are connected in such a way that current is nullified. So it is not possible to use over current with REF. – In a High impedance circuit, stabilizing resistor and metrosil will be part of the ct circuit, so it’s not advisable to combine both in the same ct core – Actually, we have commissioned many projects like this. The only thing we extended inputs to overcurrent element first then conjugated with neutral ct adding metrosil and stabilization resistance and fed to REF element. – Technically we don’t find any issue. Maybe you have any practical experience, please share for taking care. Phase ct and neutral ct should be paralleled in such a way that the current is nullified during normal conditions. Further, how the OC relay will get the correct measurement with a high impedance circuit? Please check your secondary circuits – High impedance coil input to relay is dedicated and it is voltage-operated although we give current as an input. However, OC elements core must be different than high Z core. -Are you using RET 670 relay? – Technically not correct. It may work but note that REF opération depand on CT magnétisation characteristics. It can malfunction also. REF should not operate for external faults. This is RET 670 relay CT connection for REF and over current used

– I support everyone’s input if the overcurrent element is not in the relay and phase CT star point is not made thru the relay and parallel with neutral ct. – It all depends on the relay features and how you are making start point phase CTs. Thanks for all your inputs. – Hi do anyone have abb ret 543 relay communication software – What should be the value of coil current taken by a trip coil of the breaker? – 400 kV GE make Breaker – Nonmagnetic cable gland is required in single-core DC cables?
– I am facing a problem with the abb rel670 relay. When the line is charged condition with both main and tie breakers in close position. If we open the main breaker, abb rel 670 is sending DT on another end. But we check the DT send logic, it is ok we checked it by taking a shutdown. – What will be the problem? – This is the normal logic for DT. DT is for Over Voltage, Manual Open, LBB, and Busbar trip. – On manual-open main CB, DT will send only if tie CB is already open – Ok. Tie CB status is given to this relay? But here the problem is when is in charged condition with both main & tie CB in the closed condition when we open the main CB only DT is sending – Normally REL670 will not mal operate. I think there may be an issue with the logic. – You check online signal monitoring and find out which outputs are energized during that time
– main incomer breaker of capacitor bank get trips by using relay when the power factor exceeds 0.86. The capacitor banks are newly installed. What May the reason for capacitor banks to draw more current – Did u check each capacitor’s bank-wise currents? – Check the load settings of the breaker. – We are using Tapcon 320 expert in one of our sites, in which we are trying to communicate the Tapcon using the ethernet port. During which link/activity light is not glowing in ethernet port. Tapcon is showing error event 38. No connection to the communication interface card. Communication info is showing as blank; no version available in the Tapcon
Hello, thank you for visiting our site. By joining our WhatsApp and Telegram groups, you can share your problems with electrical engineers and help out each other.
– If there was a fault during the charging, only the setting of high set elements HS1 and HS2 were there. If the value of the current sense by the relay is more than the set point, the relay generates the tripping command?
– Sel is using two functions at the same time. Blocking (cross block) plus harmonic restraint. In that case, if both functions are working in parallel, and during energization, the relay detects fault current. Or high current in any phase with little or no harmonics. Harmonic restraints func will issue trips without going towards high set or unrestraint.
– What is the DCRP approval? – For Ministry approval in Oman.
– Y 67 function is always +45 degrees? – Even I also have seen + 30. So it depends on how the earthing system achieved.
– In a line that has underground cables & OHL lines together how do they calculate distance setting? – The total impedance will be ohl+ug – No, it’s called a hybrid feeder. Current differential with backup distance protections. distance protection zone 1 should be calculated accordingly from the OHL end. – I think in this case separate Zone is added to the Underground feeder to block Auto Reclosure – but FO can’t be laid along with OHL. – What if the feeder has more pieces of cable combined with OHL, Where the exact zone can’t be defined? – Why VFD isn’t contributing the fault current into the system? – FO can be layed along with OHL. We have Differential protection in line through FO cable
– My relay version is 5. can I use this. – Your relay is pickup still not operated. – CB compartment sf6 gas low in stage 1 or 2.? – I think the alarm is stage 1 trip is stage 2. – UV1 IS AN ALARM. – If possible can you change Remote to local? – Please check the configuration, if you giving a start for UV1. It will not trip, in Siemens Relay, UV will operate when the minimum current setting is off. Please check in this relay also if the Minimum current requirement is there means to make it Off, Otherwise, check any block is given. For example VT MCB Off status like that.
– from the top near the main display 50 operate LED and 51 operate LED light blinking with red color, so what is the meaning of this? -Now transformer operates with this condition, and only one feeder is loaded with 5 amp only.
– So is any problem arise in this type of condition? And also how to reset this one to get the normal operation? – If the master trip has operated…just reset the master trip relay and charge the breaker. – To rest LEDs just press clear and go through the navigation.
– Can I get the default passwords of 7sj82 & 7ut85? – available on siemens website
-How do we calculate the tap ratio? Every time shows While I upload file to new relay, may I know what’s problem is? – Check the error – Existing file details are Configuration version: V07.31 Communication configuration version: V07.54 – Use the same version to extract the file other else download offline and then try
– New relay firmware version V 07.54 Can’t connect with a new relay. Not communicating with new relay .. every time failed. – connect by front port through of 7sj82 relay – Check if you can see the relay in your online connection. Relay firmware version V07.54 and Existing file firmware version V07.31 Maybe you have a problem with the USB driver. – It’s necessary to install the same firmware version on your computer – The Protocols device driver is installed too?
– Line voltage inject 30 degrees lead to phase voltage, Ryb 0 _120 120 – Check voltage across the coil point – Manual have? – Check your schematic drawing
– What is the reason for L1-E, L2-E, L3-E voltage higher than L1-N, L2-N, L3-N? – May be neutral is at some potential higher than earth potential. It is feeding a temporary generator and at the generator, side neutral was grounded – Maybe that grounding is not proper -Neutral is not properly grounded, therefore proper reading is coming w.r.t earth instead of neutral.
– How can I change 7UT85 Relay input by DIGSI 5? – How can I change 7sj82 relay output (NO/NC) by software? – Through CFC only
– how to update the firmware of GE Relay type MIF II. – I have a problem with the magnetic balance test in the transformer. lv side magnetic balance is ok but the HV side is not okay? – Please check proper termination of cables and also check any carbonization at the terminal point
– Then there are any flux leakages inside any core is more as compared to other cores where the winding is done. – Try to demagnetize the core. – Connect LV supply to LV side and switch ON & OFF several times say 20 – before magnetic balance which test had you perform – If vector test or any other test u have performed then this type of error may occur
– If u have done DC winding resistance test then there may be the possibility of demagnetization of core – How can I do time synchronization through SNTP ON REF615? – I changed the IP address but the time and date are not synchronous.
– Is it a new CT or old? 1) As it is primary wounded CT, insulation fails between primary to secondary windings. Because of voids presence in epoxy moldings. 2) when it is loaded condition, secondary circuits may be opened and leads to high voltage on its terminals which leads to insulation fails on the secondary coil and inter turns fault happened. – This old one.. and in-cabin we found humidity. – CT circuit is ok. Because I already checked through injections of current. – Then in this case more moisture contents are present in primary winding molding portions which lead to such. – proceed to partial discharge (PD) tests
– anything can cause a flash inside the switchgear itself? which can be found during maintenance? – all this can be found during maintenance test/troubleshooting/clearance for normally open Bay. – broken CT / crack on the body/insulation breaks down. once a flash happened no one can be 100% exactly sure what exactly causes the problem inside the SWG parts. if Arc flash happened to the old switchgear I would inspect and test the other CT inside the substation.
– test CT and visualizy check – to spare panel / normally open, etc – CT is not affected by any external impact. Failure happens inside the CT itself
– For these results transformer is healthy and if there is a problem what it could be? – Red phase Resistance – What is the problem of the red phase? – Used new CT’S with new switchgear. – I think the red phase is dead short – Why is the second phase to phase and phase to neutral is same value?
– I want to know why you see the red phase is defective – Have you checked the factory test report? – I didn’t find it – But due to physical inspection we saw suite on yellow phase – It seems the yellow phase flashed – What about IR value? – But I am so sure that Y I have the result for discussion – what is IR? – Insulation resistance – Primary and secondary are separate coils Hv – ground = 18Gohm LV – Ground = 18 M ohm HV – LV = 42 G ohm – RY and BR values are equal – YB mostly 2 times – So are PHASE only possible to short? – If so that would also reflect in ratio, vector group, magnetizing current? – That is the nameplate of that transformer – Are you measure these test – Sorry this is delta winding so -why phase may open, How do you measure these results? By using multimeter or transformers winding resistance measurement kits like TRM or CPC 100 ?? – If you use multimeter secondary value will show a minimum of 0.1 ohms in multimeter but if you use proper testing equipment means values to be in milliohms – Yes for secondary should use this equipment – What I think why phase is open hence when you measure YB the result =RY + RB, see even vector group connection diagram – Actually, if it is star means red short but this is delta so yellow should open – Multimeter

Scroll down and you can see that the device does not have a front panel. Drag and drop a front panel liberally and then check the consistency – What’s cb2? – What should I do about this? – Your DIGSI need to have the same P.Set as the device have, So update your DIGSI which is suitable for your device – Where 2 generators are sharing a network load both are in droop configuration? What would be the effect of manually increasing the speed on one of the generators? – 1. If the network is grid-connected, the frequency is locked, hence the generator will take more load.
– If it is an isolated system, then system frequency will increase? However, when 2Gens ate running one should be master and the other should be in droop -What is droop configuration? – You’ll find this in the turbine control panel. Generally, For turbine control in grid sync condition or load sharing mode.
– What is the reason the generator shaft current would be increased? – Rotor Earth fault with Pulse injection or any other method? – In the shaft, we have CT and the CT cable connected to the shaft current monitoring device – Can we able to communicate through a Multimode patch cord on a Single-mode port? anybody knows pls clear me. Insulation failure of rotor wdg? – No everything it’s OK actually when the turbine rotates high speed the shaft current also increase that I want to know what are the would-be shaft current increase – shaft current increased means, on load if MVAr is High that time shaft current is higher side if the load is less than rated and MVAr is low u get low shaft current

The final setting is 85v stage 1 pick up so when I reduced the voltage from 100 until 85V its picked up LED & BO Also but When I need to Chek drop up it will drop up only 101 V – So it’s showing when the system is healthy to still UV is not reset. So how can I make drop up LED & BO before Nominal voltage 100V – You want to Decrease the drop-off ratio, this setting will come additional setting check – My drop-off ratio is 1.2. I think to keep a minimum of 1.05 – So you will get 85×1.05=89.25V – actually, the secondary of a bushing CT is connected with AVR for OLTC because AVR needs the ongoing load value of a transformer. This means that in case of overloading conditions, AVR will be blocked. So, one CT is enough for giving a response. – Here in all OLTC, CT is connected in Y Phase only. Is there any specific reason for it? – Maybe it’s a practice – AVR is used just to maintain the Nominal voltage. This CT is are using only for measuring purposes. Not protection purpose. So one phrase is enough for AVR – What is the need for measuring current in OLTC? -: In AVR CT they are using 2 purpose 1)when current reach 120 % as per customer AVR will not give rise or lower command (AVR BLOCK) 2)circulating reactive current detection That CT is used for winding temperature measurement

– Hi, anybody has a tool for making an operating curve for OC, EF, Overflux where I can merge 2 to 3 stage DT/IDMT Related to IEC 618590 protocol. I need to merge Generator Over flux and my proposed setting DT/IDMT needs to merge on the graph. – Do anyone knows what is the purpose of the Lightning arrester. I know the purpose of surge arrester But need to know why we use lightning words especially lightning is quick, like 50us, and surger is to 200ms to 1000m. lightning has bigger voltage, and surge bigger energy. – Lightning arrester is used for high-voltage against natural phenomena. a surge arrester is used for high-voltage -Please explain a simple process of how this occurs with an example if possible for you – Lightning arrester..1)used in buildings is a plain rod with ionizing effect and transmits the high energy to the ground..2) used in switchyards and generator terminals is an NLR device which conducts the high energy to ground, it can also be in a combination of surge capacitor depending upon the equipment being protected.
– What will happen when lightning occurs on a transmission line. Then will it travel to substations? – OHGW is used to protect T/L from lighting. It didn’t travel to substations, however, each piece of equipment in the substation has a separate bodyguard for lighting – Then sir why do we use a lightening word for LA If is not protected from lightening ie from the sky – LA is installed in a substation near T/F. In starting also Means incoming of Line. Sometimes on both sides of T/F. In some, they are only installed on the HV side. – That’s why the first equipment in swyd where this transmission line ends is the LA to protect from lightning and surges as well. – Shield wire is also part of the lightning protection system to protect trafo from switching surges.
– Why secondary side of CT is shorted? – How to measure PT resistance??? – With the help of the resistance meter kit. – Do you mean pt winding resistance? Yup, insulation resistance with the help of Megger?
-Earthing should be chosen from the VT body or another point? – What is the range (min) & (max) value of insulation resistance? – Because at the secondary side current is hardly 1 or 5A so in that case voltage is too much If we open the terminal there is a chance of the blast – What will happen when the secondary is open-circuited and your primary is on load, according to the transformation ratio, the primary has to be there is secondary, As the secondary is open-circuited, the current will flow through the core. – As the core has a high impedance, even a small amount of current through it will produce an extra-high voltage which eventually fails the insulation and a short circuit happens. – So in short never leave your secondary in CT open circuit or lose. – Any spare core should be shorted – A PT or VT has its primary resistance (is from the HV tap node to the ground) in the range of 10-100 ohms.
– It is an old distance relay, and it works on the principle of resistance per phase? – This is not a distance relay. This I’d line differential relay for a short distance with a pilot wire protection system. – The two pilot wires are calculated with a loop resistance 2*R and a resistor R – So how can I calculate the setting? any procedure? – The Instrument transformers do alter the original signal during transformation, so the relay allows for a minimum phase shift during transformation, so the phase shift can be accommodated – It is a family of the DLN Should give a basic understanding 18/abb pcm600, abb14 –IEC 61850 training Bhatti: I try to do so. – Transmission line protection by pilot wires (pilot relaying) is limited to 30 to 40 km in route length. For longer transmission lines and sub-transmission lines or even distribution feeders, distance protection is used. – So they are in theory born of the same philosophy of resistance per length of the chosen pilot wires – This is limited to the pilot wire differential applications.
– What will happen if one CT sec. star point towards the object and one CT sec away from the object in differential protection? – The relay will act for external fault.
– I have one question: what is the formula or how do we calculate the arc flash energy values for the specific switchgear? – There would be a non-zero component of differential current on all phases. t = time duration of the fault – You may also star towards the object and load. these features can be set in the above-named relays Once it has clocking features, it also has to come with sequence tweaking for they work together to give the microprocessor a sense of rotating. – DY set the clock at 6 to invert, not o
– Anybody sends an IEEE guide for safety in SUBSTATIONS earthing Testing parameters. – Can You share any testing procedure and method of transformer testing Pdf? Please
– I have to replace existing Solkar Rf relays with Numerical relays. What consequences need to face during these modifications? Someone has done this job before please suggest a line of actions, a logical sequence without interruption of buses.
– What is Digsi 4 & Digsi 5 software? how to use this? – First of all, you need to install it on your computer. Digsi 5 and 4 are the software we used to configure the Siemens Siprotec relay. – Can I configure Siemens all types of the relay to use this software? – I don’t think. Digsi is proprietary software.

– Voltage measurements issue across the output of the charger – Voltage across the phase- neutral found ok. 120 v. But across the phase – the ground couldn’t be found. Slowly go to zero volts. – How much is neutral to the ground? What is the charger rating? – Zero volt – Maximum current 27.2 Amp – That is what we call floating voltage, phantom voltage (Ghost Voltage) -The reason for this is there is no real link between those two points Or there is saturation in the source hence the load loading the source phenomenon -This can happen if, for example, you are trying to power a 100W 120v rated electric bulb using the output from a source that has a lesser burden let’s say a VT with a 50VA burden. – Check for Case 3 – what is the actual reason behind this issue – I mean why did it happen like this – If case 1 is suspected Look for a digital multimeter with a LoZ voltage reading range check for potential. If the value is zero still check for Case 2. Short the two suspected terminals through a 2 Amp fuse. If the fuse does not blow Check for Case 3, Look at the burden of the transformer, and test the in-built transformer for coil continuity. – By which time you would have already found your problem? – Please note that all the steps have to be done with any multimeter that has the (LoZ) Auto Voltmeter. Start a Private chat with me, if you still need help troubleshooting – In PCM 600 SOFTWARE is unable to read the relay. Can anyone help? – It says the relay is an inconsistent state. Try again to read from the relay. Make sure u are on the main page of HMI – Check the IP address. Then relay reset using the power of the relay. Then try to connect and hope to resolve – Made Power on/off then the PCM 600 read from Relay – What are the criteria for min line length protected through modern distance relay? – I think it can be 100 meters. There are no criteria it’s all about economics and how sensitive the supply is No minimum or maximum length! Notice that during shunt voltage becomes very small and currently becomes very high, hence admittance tends to move towards infinity. But for a very short distance, line differential should be preferred. The 9 members of the matrices can only be compared to the set values by the relay microprocessor as the diagonal members are in theory smaller than others. – Distance protection zone 2,3 operating time coordination with backup OC n EF protection if not meet grading shall we block all zones – Hi. I have one key question short circuit ratings are normally given in 1 sec or 3 sec. For instance 25Ka for 3 sec or may 25ka for 1 sec.
-So how do we choose 1 sec or 3 sec or decide or go for type testing – The essence of this rating supposedly on switchgear is to know the limit you can push the interrupter to, but it is not good to test switchgear at these values (not that you can get a 25KA test kit) because this would be defeating the purpose of NDT Non-Destructive Testing of the switchgear interrupter.
And for a transformer, motor, and other devices, if Isc is on the nameplate then it is the current that would spoil the coil if it lasts 1 – 3secs. The maximum short circuit would be less than or equal to the rated current times the inverse impedance voltage.

Any idea what can cause this issue? The sec side of the TX is HV VSD which is running fine without creating any issue. – Tripping is immediate after startup? -No. The system sometimes runs for even half an hour and then just trips for no reason without even introducing a new load – More. ACB should have a built-in event recorder. It will give you cause and time of tripping -How to download that? Is there software or something? – Try step by step to analyze and move forward to correct – No. It should have an LCD that shows real-time current. Configuration settings and the event history of ladt tripping – Can you share its screenshot or video – Yes correct. Will ask for the photos once it will occur again. Right now the system is working fine for almost 9hrs
-Quick CMC through Distance protection test possible sir? Or advanced Distance module required for the test? -Testing is possible, but need to manually calculate the current and voltage value for a specific impedance, in quick CMC. – May I get manually calculation of Impedance – You can select directly impedance instead of Voltage & Current…option available… – Distance protection test report may I get sir? Calculation of distance protection may I get sir? Please share. – Artificially Line Ground fault created on Raigarh puglur HVDC to tune relay settings. – Always theoretical & assumption workouts may not give accuracy. Sometimes needs to be tuned in a practical way – I saw firsthand something like this go wrong, and it was fatal – I am working in HVDC Raigarh and this line fault is tried several times in the commissioning period to get accurate tuning of the online dc line fault locator. – I know it is really dangerous to carry out the line fault successfully – There are remote controlled projectile devices, so try to be on a safe side -: How is that fault created?
-I need this relay technical manual anyone has kindly shared with me – Is it possible to share ur valuable advice on the following concern. Resistive/impedance reduced fault happens when the fault is not happening at the first bus, say after x km of line/earth. Recall that the line has intrinsic properties of ( y + j z) ohm/km. Also, there is an intrinsic resistivity of the earth which increases its resistance by distance R = pL/A – Why do we need DEF protection in distance? But 87 cannot detect Internal faults? Is REF more sensitive as compared to the differential – I read somewhere that phase-to-ground faults are highly resistive, and to clear these faults we need more sensitive protection like DEF? – SEF not DEF – I think he’s asking about the Directional Earth fault – 87 detects internal faults on phases – Yes I am asking about DEF also which is mostly used in distance relays for transmission lines – What’s the stability test? How can perform for the 66 VK substation? – Please send the method procedure for this test. – When the energized line comes in contact with a grounded thing like a tree branch it finds its path through the ground back to the substation. Because the magnitude of the current may not be enough to offset the 0.1 – 0.2 I> set for earth fault, it detects only through the NGCT a negative feedback current more like the SBEF but it monitors when there is a reverse from s2 – s1 This means DEF is used because it is used primarily for phase to ground faults and is more sensitive to Ph-G faults?
– Anybody knows about the multi-stage series power filter? – There is no potential difference hence no effect -No. due to the complete cycle.. neutral should be needed. -Consider Phase to phase then? – I guess. Phase to phase, it will come as shock as the circuit is completed – It will be a short circuit -This person will get electrocuted based on the condition of his hands (ie., Surface resistance) and his body resistance. Pls remember the step potential diag, with differences, the earth is replaced with conductor and legs with hands. – We need to know the cable impedance per meter, the current flowing, and distance hand-hand -Voltage drop is negligible.

– How can calculate the Vector group of CT? – CT doesn’t have any VG – However, they do have minimal phase shifts – Just D or Y connection depending on the application? -basically, this CT is used for Differential protection. Star is best for the object to be protected. Star point on all s2 for HV CTs. Star point on all s1 for LV CTs -This is center taped so s3 for full ratio or s2 for half ratio
– Does anybody assist what is slope value for the single side-feed line? I saw the manual they didn’t mention value. Is there any fixed value for that slope? In setting also didn’t find value for that single feed value. – Slopes are calculated! And it is the boundaries that set trip areas and operating regions. What is your operation criterion?
– When I want to test different Protection for DYN11 using quick CMC how much the angle of secondary current when I use 0 angles for primary side current certainly for the same phase. – For Dyn11. 180+30=210 & balance angle Should be applied in LV side – why +30 for 11 I guess it is – 30 – -330(CW)=30(ACW) – Why use quick CMC? When you can use Advanced different operating characteristics? – Try any of the two and just input your system parameters for both test object and system. Omicron would do the rest for you. – Actually, as you said it is better but there was a problem. When I open diff characteristic the connection between CMC and pc interrupted – Have you ever had the same issue? I don’t know the reason
-What CMC model do you have? – Cmc 356 – Okay then you should be having RJ45 Network cable – When I use OC. quick no problem When I use advance diff the problem occurs – Download the latest model of Test universe and install it. Most likely your antivirus engulfed some registries that contain omicron executable files – Deactivate it when installing and reactivate back shortly after. Check if u have a license for advance differential

– what‘s the reason for Using the function 59N and if necessary creating a ring loop for all my relays in the SWGR?? – Do you have information about C&P in Substation? -132kV, 24MVAR Capacitor Banks (group 1 & 2 = each 12Mvar, 8MVAR/phase) when tested on-site by applying three phases 400V give acceptable values of 318mA on each phase thru clamp meter. – However, when group 2 of the blue phase was intentionally cut off for testing purposes, it showed the following suspicious result? (instead of 318mA) Blue: Group-1 160mA (normal) and group-2: 0A (acceptable value) – What is the reason behind 290mA values for red and yellow? It shouldn’t be 318mA? Anyone, please – What could be the solution for the above error – Is it over Ethernet or Front port – Also you can ignore the error. In the case of the front port try with Moxacable – Schneider Recommenda Moxa cable for front port communication. It’s with Mona cable and front port -What is the communication port number your using? – Can you send the photo of the device manager moxa driver settings? – Use com1 for communication. If still not able to send a file, try to send the required parameters only. Open setting file, say you want to send VT PRIMARY, then click on and send data to the device

– In my power plant, DC system +ve is solidly earthed. Checking it through megger to make the BGFT kit but am now able to locate the fault. Due to a system running I cannot switch off the dc controlled feeders. Can anyone suggest to me any other option, idea, or any other kit through which I can get the help.? – Megger BGFT is the best way to locate the DC ground fault without switching off DC circuits, u just need to measure the impedance from the main source until reaching the branch circuit that has the fault – But it is failed at my location to trace the fault. As per OEM due to complex DC circuits and the use of electronic cards in breaker feeders is not allowing the kit to trace. But this should not be the reason. Looking for some more options to identify – I have a question for everybody, Anyone has a document or example for the cargability of CTS? – I am doing testing for sepam87T, diff function does not operate but other functions in the relay are operating. I tried to fix this issue by activation output and led but still not working. The relay read current on both sides and read diff current but there is no output – I didn’t check sepam87T. CT Matching Factor (ICT) Star point of the CT connection Vector connections of TR While injecting dual Current, check the phase angle magnitude /Compensation. – Check output configuration, And Confirm any Blocking signal generate due to Breaker feedback / CTS… – Actually, I checked the output configuration. What do you mean by blocking? For Example 3 Wdg differential, only you are injecting Two Wdg, Third wdy CTS may Block the output But Function will work…
– Can anyone help me to resolve this issue, I installed PCM for the first time. – can you see some QR codes in IED? – No, nothing like this on IED – 220kv Alstom china, breaker drawing required, kindly share – Hello!

– 90% stator earth fault protection Test process please share with me. – Have any process. Voltage injected in relay PT coil but not trip. What is the protection operating criterion? Is it only open delta voltage-based or NGT voltage-based or both? – Open delta voltage based – Inject normal voltage in any one phase of terminal pt so that no VT alarm came. Then inject in open delta pt and NGT as setting values. It should trip – Setting value 14 volt – Anyone can give an idea about starting auxiliary relays manufacturing? -Setting value injected Ji .. but not coming trip /alarm – Is there any other ct or vt alarm coming during voltage injection? – LV BCT can’t be ignored for REF. For LV side BCT is mandatory for REF SCHEME – So anybody has used IPCT? What are its consequences? – These connections might be possible when one of the windings of t/f is delta connected (like dyn11, ynd1, etc.) but these connections can’t be made on auto t/f – So, you mean either higher values or IPCTs should be used for mismatched REF if it is connected!

– Anyone knows how to check the capacitor with a multimeter? – CHECK THE AMPERE ON EACH PHASE IF IT IS HEALTHY IT WILL SHOW AMPERE ON EACH PHASE. RESPECTIVELY IF THE PHASE SHOWS ZERO AMP THEN IT IS DAMAGED.
– Can anyone help to identify, in actuality what the main fault is? It occurred last week. – master and o/c & E/F fault relay trip. And Simultaneously line Side SF6 breaker trip. – We have 9 MVA, two power transformers in 66 kV Switchyard Fault occur only on transformer 1 and only line Side SF6 breaker trip, I don’t understand this. Please help. – O/c & e/f I think backup protection for short circuits or internal faults inside the TR.. check your protection scheme to understand further. – all I can tell u is, it may be a heavy imbalance in the loading of the line. if it occurs once in a while & goes away please note this & revise your settings through relay coordination.
– Anyone here, who can tell me about solenoids? – Like this one solenoid. – Our Switchyard SLD, also in case SF6 breaker out of 3 poles 1 pole does not get close (remains open). Kindly check this out.
– On my site, 33kv ht cable IR values are R= 60 megaohm, Y=1 gigaohm, B =1 gigaohm. Please give suggestions if energies the cable. – How much voltage was injected into the cable? – 1000 volt
– Try to inject 5kv. From my experience, If you got the same value you can charge the cable. – 60 megaohm is acceptable if I injected 5kv. – If is it possible to keep the cable in sunlight, then conduct IR you can get better value. – I had charged the 11kv bus when I got cable IR around 10 M ohm. – Clean the cable jointing kit perfectly, then means if you find any carbon in the cable termination. IR value can also improve by doing this. – Around 1km cable laid. – I Am not saying to clean all the cable. Just clean only the HV Termination kit.
– If it is possible to try to do a route survey also as per standard minimum of 100 megaohms is required? – Use a blower to heat the termination side it is the sleeve.
– Can anyone tell me the difference between the Hipot test and the IR Test of cables? – In the Hipot test, we check magnetic earth leakage current. In IR test check cable insulation.
– the procedure in the Hipot test if it’s 11 KV we have to apply 28 kV for 1 minute and measure the leakage current in Milliamps, in the IR test we have to use 5 KV DC Megger and measure the resistance in megaohms
– Why it is 28kv? why can’t we measure with 5kv? – The Hipot test formula =80% ((2*rated voltage) +1kv) – In the formula, it’s not coming 28 kV – For your understanding, I sent the Hipot test voltage of switchgear as per standard, for differentiating Hipot and IR Test.
