protection relay 2

– During one phase PT failure, will overflux relay work? Has anyone seen this kind of voltage transformer connection?
– Why b phase winding is grounded on the secondary side?
– Can u share nameplate details of the PT
– yes, in an oil company, usually they only use 2 PT input and make it as delta connection in relay
20digsi 4, 11:51 – abb pcm600: That’s an open delta voltage transformer (or potential transformer)
20digsi 4, 11:52 – abb pcm600: It’s mainly used as an input to detect earth faults using neutral voltage displacement ..
20digsi 4, 11:54 – abb pcm600: 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 ….
20digsi 4, 11:55 – abb pcm600: Such schemes are used in ungrounded systems or on generator – transformer sets …. there is no path for earth fault …
20digsi 4, 11:57 – abb pcm600: Sorry open wye … but the scheme is same …
20digsi 4, 13:04 – abb pcm600: Open delta connection , Yellow phase normally will ground.

But as per drawing seen some conflict..
Norammly 2 VT Winding we can seen..
20digsi 4, 13:05 – abb pcm600: IMG-20200420-WA0001.jpg (file attached)
Normally like this

20digsi 4, 13:05 – abb pcm600: This is star connection with y phase grounded. Not an open delta. I was reading on internet its some old practice followed in UK.
20digsi 4, 13:35 – abb pcm600: Yeah … that’s an open Wye or Open Star … works the same way ..
20digsi 4, 20:11 – abb pcm600:

Mohamed badr: What is Apts scheme
28digsi 4, 19:15 -abb pcm600“: This message was deleted
28digsi 4, 19:16 -abb pcm600“:
For this system, with the two Transformers secondary breakers and the tie breaker are normally closed, and installing directional on the two secondaries, I need some guid on how to Make the setting for the directional, And if any one has a similar case i will be glad if he shares his settings and how to Make them
29digsi 4, 06:41 – abb pcm600: the intention of the Directional on the secondary side is for backup protection? i ever encounter 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. DOC (Isetting : full txf rating, TMS:0.1 , +30degree), DEF (Isetting: 0.1A, TMS: 0.1, 0 degree)

06etap, 11:54 -abb pcm600: PLC is communicating with another PLC over profibus
06etap, 11:56 – abb pcm600: Well, it can be a lot of stuff, but the first thing I always have for this alarm. SISTEM FAULT it means that you may have some unit programmed inside your PLC that is not connected in the field.
06etap, 11:56 – abb pcm600: So if it still works let it be
06etap, 11:56 -abb pcm600: with that alarm all parameters of slave address beocme red
06etap, 11:56 -abb pcm600: ok
06etap, 11:57 – abb pcm600: Is not something to concern, just be sure you have a good backup of the PLC program.
06etap, 11:58 -abb pcm600: but if it remains,it will not let startup of Engine
06etap, 12:09 – abb pcm600: 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 Years with this SF and nothing ever happend.

07etap, 22:45 – abb pcm600: Hi everyone
This not Bad contact Rubbon the message is clear (Micom Booting) with Led Alarm lightning in red Fast…
It’s like PC booting
I think it’s microprocessor …issue
07etap, 22:51 – abb pcm600: We have faced the same problem in our reliance industries jamnagar plant and Alstom it self give us 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. Their is no any chance of error in relay or bugs like microprocessor.

14etap, 13:38 – abb pcm600: okthanks
14etap, 15:49 – abb pcm600: Hello to all
What is the standard setting of the characteristic angle for directional overcurrent phase and ground (67/67N)?
14etap, 15:54 – abb pcm600: For typical distribution networks (upto 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.
14etap, 15:55 – abb pcm600: However different scenarios may require different angles … and have to be worked out.
14etap, 15:58 – abb pcm600: This angle for directional phase overcurrent? What about the angle for directional ground overcurrent 67N?
14etap, 15:59 – abb pcm600: Are there any refferences for how to Make the setting for directional phase and ground overcurrent 67/67N?
14etap, 16:00 – abb pcm600: I would typically read the relay manual …
14etap, 16:00 – abb pcm600: And use the default recommended value
14etap, 16:01 – abb pcm600: The actual math behind setting them can be very tricky ..
14etap, 16:05 – abb pcm600: Which relay are you using ?
14etap, 16:09 – abb pcm600: Sepam s40
14etap, 16:10 – abb pcm600: The application is two parallel Transformers
14etap, 16:21 – abb pcm600: What’s the voltage level and how far is the relay from the supply transformer ?
14etap, 17:11 -abb pcm600“: From experience, RCA is 20~40
14etap, 17:42 – abb pcm600: For 67N, the value is dependent on the type of grounding.
Please refer to NPAG, it was clearly explained there
14etap, 17:45 – abb pcm600: Anyone have digsi4 Activation Key.?
14etap, 17:46 – abb pcm600: And for 67, if I am not mistaken, RCA is set based on impedance angle of the system

28etap, 12:15 – abb pcm600″: Hi Guys, I have a question
For 220KV level, which is suitable either CVT or IVT(PT)? And why
28etap, 12:16 – abb pcm600″: Usually we are adopting IVT(PT) in Andhra Pradesh India
28etap, 12:16 – abb pcm600: CVT always
28etap, 12:17 – abb pcm600″: Sir can you please support your statement… As we have observed the drift in secondary voltages are more in CVT compared to IVT over time span
28etap, 12:19 – abb pcm600: Mainly installation reasons …. they are lighter, cheaper
28etap, 12:20 – abb pcm600: Safer (transfer of emf when fault occurs)as there is no direct connection to the primary voltage source .
28etap, 12:20 – abb pcm600: Can you explain how does the voltage drift?
28etap, 12:22 – abb pcm600″: Deterioration in the capacitance levels over period of operations results in variations in secondary voltages
28etap, 12:29 – abb pcm600: Can’t that be fixed during maintenance? (Note: I don’t have any experience in maintenance and operation)
28etap, 12:31 – abb pcm600″: Even I don’t any experience in Maintenance. But I am not sure we can improve this in effective manner
28etap, 12:31 – abb pcm600: CVT for transmission circuits or High Voltage i.e greater than 66kV and IVT for distribution circuits 33kV and below
28etap, 12:33 – abb pcm600″: Moreover we are mostly using IVT in 220KV levels also so, I am not aware of fixing methods
28etap, 14:50 – abb pcm600: I believe it’s a cost trade off.
In India IVTs in 220kV class are more affordable than CVT. 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 coupling capacitor for PLCC communications as well.
28etap, 14:50 – abb pcm600: That’s my understanding

28etap, 18:05 – abb pcm600:
Hi guys,
Why when we calculate short circuit at transformer secondary we should consider no load ph to phase voltage not rated voltage?!
28etap, 18:26 – abb pcm600: Yes.CVT is more affordable to be used since the consideration of its(equipments) isolation to H.V.
28etap, 18:30 – abb pcm600: Yes, we can track and analyze its dissipation factor( Tan Delta measurement) 👍👍

01etap, 23:37 -abb pcm600: Cheapest bro
02etap, 04:00 – abb pcm600: Another reason stones are used is ‘cause it helps in fire 🔥 mitigation, especially where oil traps/ sump pumps are not available.

The leaked oil will have less surface area exposed to air that can burn, there by reducing the fire hazard.

Dear All,
We need to do 87L test, as you can see in secondary current to relay is very low 0.044A. We did secondary injection for GE L90 relay and found it doesn’t read 0.044A.

I have a problem in Micom P443 for Distance Protection. I have a problem in System Checks for Autoreclose,anyone can tell me what is the difference between CS1 Close Enable dan C/S AR Immediate ??
30etap, 12:35 -abb pcm600″: Cs1 close enable is the setting of sync check on which you want to recloser the cirxuit breaker like on Live Line Live Bus or Live bus Dead Line or Dead Line Dead Bus
30etap, 12:37 -abb pcm600″: 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,
30etap, 12:37 -abb pcm600″: Like for example if dead time is 1 sec
30etap, 12:38 -abb pcm600″: And system check conditions are met during 0.6 seconds of dead time ,then relay will give reclose command without waiting for the remaining 0.4seconds of dead time,
30etap, 12:39 -abb pcm600″: But you habe disables the system check conditions on shot1 that means it will reclose the breaker wothout looking into any system check conditions,
30etap, 12:39 -abb pcm600″: Sys check on shot 1 should be enabled too,

30etap, 19:01 – abb pcm600: Somebody help?
30etap, 20:56 – abb pcm600: It depends on the loading.. The higher its loading, more power 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 be overheat..

15etap 17:34 – abb pcm600: What s the difference?
15etap 17:35 – abb pcm600: Because some tell me it is the max number of trips
15etap 17:37 – abb pcm600: RCBO stands for residual current circuit breaker. It can open faults upto 6000A. It can be used for short circuit protection as well as sensitive faults of 30ma.

RCD is 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

What is your experience…
Please share
25etap 21:20 -abb pcm600: Normally frequency of Numerical Relay testing depends on the utility practices.

In our utility we do annually. But in my opinion it is not required annually.
Numerical relay can be tested 5 years once.
Scheme testing can be done annually.

31etap, 20:14 – abb pcm600: ?!
31etap, 20:14 – abb pcm600: Yeah …
31etap, 20:14 – abb pcm600: Can i have it please 🙏
31etap, 20:15 – abb pcm600: Ok … I’ll send the pcm600 files tomorrow …
31etap, 20:15 – abb pcm600: Anything in particular you are after !’vv
31etap, 20:15 – abb pcm600: ??
31etap, 20:16 – abb pcm600: Current line differential relays are fairly straightforward..
31etap, 20:17 – abb pcm600: Is there a difference ?!
31etap, 20:43 – abb pcm600: Anyone knows what is the problem when a source (power plant) transmit power to a substation, then the neutral current monitored in power meter is a bit higher normally…
31etap, 20:46 – abb pcm600: I know that It means that there is an unbalance current on each phase. But what else can be that causes of phenomenon..
31etap, 20:49 – abb pcm600: The P.F on phase R and S is lagging 0.9, but the phase T shows a leading P.F
02etap 20:56 – abb pcm600:
Hello guys, i need some understanding on this problem..
02etap 20:57 – abb pcm600: In case it’s internal fault, just assume that the 87 T relay and Ref relay will trip…
02etap 20:58 -abb pcm600: your understanding is correct
02etap 20:59 – abb pcm600: But apart from it, if primary Overcurrent (50/51P) works, it will trip the CB 150 kV and how avout the CB 20 kV ??
02etap 21:00 – abb pcm600: Is it required to trip the CB 20 kV too ?
02etap 21:03 – abb pcm600: 87T trip, REF not really, depend on the fault. PP fault or 3P internal fault wont initiate REF
02etap 21:04 – abb pcm600: yep… to isolate the power from LV side too, in case bus section in 20 kV side is closed
02etap 21:05 – abb pcm600″: 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 trip
02etap 21:08 – abb pcm600: REF is more sensitive for earth faults in the differential zone
02etap 21:08 – abb pcm600: If it is an earth fault REF trips faster than Diff.
02etap 21:12 – abb pcm600: Okayy..thank you everyone for the answer..
02etap 21:14 – abb pcm600: I think that 20 kV CB will need to trip too to prevent reverse power from remanent voltage (power) at Bus 20 kV side
02etap 21:15 – abb pcm600: But if there is a remanent voltage in 20 kV side, is it possible to induced voltage in primary winding to create a current..
02etap 21:16 – abb pcm600: Since you have NGR…earth fault close to neutral may nit be detected by REF
02etap 21:16 – abb pcm600: Percentage of unprotected zone can be calculated based on relay settings and CT ratio
02etap 21:31 – abb pcm600: Yes..due to the resistance, the sensitivity will be limited..
02etap 21:40 – abb pcm600: Have everyone ever tried, to induced voltage on secondary winding of step down Transformer i.e. lets say 150/33 kV. How about the primary winding transformer, does it will generate a low current or a harmonic current
02etap 23:29 -abb pcm600: Actually fault moves towards source. In actuall LV will not trip because fault current will move towards source side(150kv) side but if intertrip function is available then LV 20kv side will trip too
06etap 18:27 – abb pcm600:
06etap 18:29 – abb pcm600: Anyone knows about the calculation to get the value of Z1 Sensit. Iph>1 ? 🙏🙏
06etap 18:29 -abb pcm600″: Fault current should be above this value to identify zone 1 or zone 2 faults
06etap 18:30 – abb pcm600: 👌I got it.. But how to get this value ..
06etap 18:33 – abb pcm600: Okay. I have found it was 1.2 x CCC / CT Ratio
06etap 18:42 -abb pcm600″: Thanks
06etap 18:43 – abb pcm600: Youre welcome bro 💪

07etap 17:27 – abb pcm600:

07etap 17:30 – abb pcm600: Since I close my CB thenthe IS time starts to count to set AR Block
07etap 17:32 -abb pcm600″: If cb is manually closed than after this time CB will be considered in service and Auto Recloser function will be enabled too,
07etap 17:33 – abb pcm600: Oh i see
07etap 17:33 – abb pcm600: But why it AR block indication is appeared.
07etap 17:34 – abb pcm600: After the CB IS Time starts to count..
07etap 17:35 – abb pcm600:
Still strugling on this distance relay

    12etap20:28 – abb pcm600″: 132kV transformer HV breaker was close on NO load and LV breaker was open, but suddenly differential relay operate and give differential trip. In fault study, HV side current was 860 Amp. Somebody tell me that what could be reason??
    12etap20:30 -abb pcm600″: For how much time the transformer was on no load?
    12etap20:31 -abb pcm600″: 132/11.5kV ?
    12etap20:31 – abb pcm600″: Approximately 10 to 15 minutes

    12etap20:32 – abb pcm600″: 132/22 kV (wind power plant)
    12etap20:32 – abb pcm600: Not inrush current
    12etap20:32 -abb pcm600″: Yess
    12etap20:32 – abb pcm600″: Yes
    12etap20:32 -abb pcm600″: There must b some issue ,
    12etap20:32 – abb pcm600: So this is not inrush
    12etap20:32 -abb pcm600″: Do TTR and winding resistance,
    12etap20:35 – abb pcm600: If it is the new commissioned plant then the issue will be in relay setting otherwise check transformer winding…do the IR…
    12etap20:35 – abb pcm600″: I did excitation test @ 10 kV and results was OK.
    12etap20:36 – abb pcm600″: Plant is in operation from last 4 years.
    12etap20:37 -abb pcm600″: You will have to do TTR and winding resistance to diagnose the matter ,
    12etap20:37 -abb pcm600″: Hope you will get the problem by doing these tests,
    12etap20:37 – abb pcm600″: OK

    29etap08:51 – oijoi: We have 50/1 5p15 CT installed on 33 kv feeder whos fault current initially was very less but now Power supplier has installed 50MVA transformer 11% impedance
    29etap08:55 – abb pcm600: And fault current is almost 8000Amps, I believe I need to upgrade protection CT in order to meet high fault current
    29etap08:55 – abb pcm600: Can anyone suggest
    29etap08:56 – abb pcm600: What’s the 33kv fault level ?
    29etap08:56 – abb pcm600: Now it is 8000 amps
    29etap08:56 – abb pcm600: Fault current level
    29etap08:58 – abb pcm600: 50 MVA transformer installed at state electricity board substation and we are consumers with 33 kv feeder voltage
    29etap09:00 – abb pcm600: 50MVA 220/33 KV star/ star connected transformer 11% impedance
    29etap09:01 – abb pcm600: Is the ct used only for over current and earth fault ?
    29etap09:01 – abb pcm600: Yes 50,51, 50G, 51G
    29etap09:04 – abb pcm600: Strictly speaking, I would put 200/1 5P40 2.5 VA
    29etap09:04 – abb pcm600: However if the relays have CT saturation detection, you could go lower.
    29etap09:04 – abb pcm600: What’s the relay being used ?
    29etap09:05 – abb pcm600:
    Micom P117
    29etap09:06 – abb pcm600: P127
    29etap09:07 – abb pcm600: Do you have the CT test results. In particular the DC resistance of the CT.
    29etap09:07 – abb pcm600: No sir
    29etap09:08 – abb pcm600: Can you give your consideration or calculations for this selection
    29etap09:08 – abb pcm600: 8000/200 =40.
    29etap09:09 – abb pcm600: So you need an accuracy limit factor of 40, with a low burden
  • 9etap09:09 – abb pcm600: You won’t need much burden as the relay is numerical and installed inside the switchgear
    29etap09:10 – abb pcm600: Got it Thanks
    29etap09:10 – abb pcm600: Noted
    29etap09:11 – abb pcm600: Your existing 50/1, 15 VA may actually work if you knew the DC resistance.
    29etap09:12 – abb pcm600: Do I have to check with CT testing kit??
    29etap09:12 – abb pcm600: I believe CT supplier should I have this information
    29etap09:13 – abb pcm600: Yeas if you have a test equipment (Omicron CR analyzer or similar) that should be easily possible
    29etap09:13 – abb pcm600: That’s possible, however normally the manufacturer will not specify the DC resistance for 5P/10P class act’s. No harm in asking them though
    29etap09:13 – abb pcm600: CT’s
    29etap09:14 – abb pcm600: CT Analyser
    29etap09:15 – abb pcm600: Ok I will check with him today, as I don’t have omicron kit available near by That the only option I have
    29etap09:15 – abb pcm600: How you coordinate DC resistance with fault current
    29etap09:20 – abb pcm600: Wait
    29etap09:20 – abb pcm600: I’ll write it down can’t type it it’s a bit of a process
    29etap09:21 – abb pcm600: Ok thanks
    29etap09:28 – abb pcm600:
    29etap09:29 – abb pcm600: So if Rct<= 1.75 ohm, you can use it 29etap09:30 – abb pcm600: For a 50/1 A ct this may be achievable. 29etap12:14 – abb pcm600:
    My suggestion will be , need to Replace 33 kv side CT with ,. 1000/1A, 5P10,15 VA
    29etap12:29 – abb pcm600: With this approach, I’ld reckoned checking the pick up values.

06etap 15:17 – abb pcm600: Ynynd1
06etap 15:18 -abb pcm600″: And tertiary (delta winding) is unloaded??

What is the difference of IN-HV Deriv Angle and IN-HV Measd Angle on monitoring online
08etap 11:46 -abb pcm600″: Derived means the neutral current have been calculated by summation of IA, IB and IC where as measured means neutral wire of ct secondary is connected to neutral element of the relay, and it is actually being measured,
08etap 11:50 – abb pcm600:
08etap 12:11 – abb pcm600: What is dead zone in protection??
08etap 12:13 -abb pcm600: Dead zone is Zone between CT & Open CB
08etap 12:14 – abb pcm600: 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
08etap 13:48 – abb pcm600: Oabb pcm600 i see..IN HV deriv is neutral vector calculation, meanwhile In HV measd is a neutral REF winding
08etap 13:49 -abb pcm600″: We cannot say it is neutral ref winding until we see the setting of the relay,

10etap training0, 15:34 -digsi 5: Settings of harmonic
10etap training0, 15:45 – digsi 5: If I’m not wrong, in modern transformer because of core material , the Inrush current harmonics are sometimes less than 20% of fundamental frequency component due to which differential relay operates. So, we can keep the setting at 15%
10etap training0, 15:45 – digsi 5: For second harmonics we can keep this at 15%
10etap training0, 21:04 – digsi 5:

15etap training0, 12:33 -digsi 5: If CT gets saturated .what is solution after CT get’s saturated.We want to replace CT or any other solution
15etap training0, 12:36 -digsi 5″: CT secondary current flow to secondary winding
15etap training0, 12:36 -digsi 5: Please explain in detail
15etap training0, 13:00 – digsi 5: How are confirming that CT got saturated?

15etap training0, 13:53 – digsi 5″: What is the burden of your CTs?
15etap training0, 13:56 – digsi 5: Saturation is purely a magnetic property issue …
So there is no alternative solution to do corrections in the circuit ..rather than core replacement.
15etap training0, 13:58 – digsi 5″: You need not replace your CT there are ways to demagnetise the ct
15etap training0, 13:59 – digsi 5: Dear Mebin
Can you explain in detail the theory of core saturation in ct ‘s
15etap training0, 14:00 -digsi 5: How can we demagnetise the CT
15etap training0, 14:01 – digsi 5: We had followed demagnetisation in transformer ..whenever we got erroneous values while testing dc winding resistance
15etap training0, 14:05 – digsi 5″: The easiest way to demagnetize a CT is to apply test current at a level that approaches it’s excitation ‘knee’, then
slowly decrease the input current to zero.This can be done with secondary excitation or primary current injection.
15etap training0, 14:07 – digsi 5″: I think some tester offer this option
15etap training0, 14:10 – digsi 5″: Like omricon ct analyzer
15etap training0, 14:10 – digsi 5″: Can you explain why you need to replace your ct

    05/etap training, 19:44 – digsi 5: Please tell the ‘distance’ below which ‘Line Differential Relay’ should be used for protection of 220 kV or 132 kV Transmission line?
    05/etap training, 20:06 – digsi 4: Line differential use mostely for under ground cable not over head line for e.g RED670 Abb line differential and for OHL REL670 will be use
    05/etap training, 20:07 – digsi 4: In addition RED670 have ability to protect distance too
    05/etap training, 20:14 – digsi 5: sir, why is it that Differential is used for cable and not line?
    05/etap training, 20:16 – digsi 4: Because with differential you are normally using fiber Optic, laying parallel with feeder
    05/etap training, 20:17 – digsi 4: It is common to use line differential for under ground cable and distance relays for over head feeders
    05/etap training, 20:18 – digsi 5: Cant we have line diff if we have OPGW with the line?
    05/etap training, 20:19 – digsi 4: As much I know there is no distance length specified for Line differential relays
    05/etap training, 20:19 – digsi 4: Line differential protection is also being used in overhead lines especially short lines and for high voltage lines that have a redundant protection such as 400 kv
    05/etap training, 20:20 – digsi 4: Yes I think possible, line can be use with opgw too, but I never face that actually in our system
    05/etap training, 20:21 – digsi 4: Right
    05/etap training, 22:24 – digsi 5: anyone has 2 phase transmission line with ‘line Differential protection’?
    05/etap training, 22:29 – digsi 5: Line differential protection is being used for very short lines say less than 1 km. We are using it on 550 metres 220kv line.

    06/etap training, 08:05 – digsi 5: sir why is it used and not Normal Inverse or Extremely Inverse?
    06/etap training, 10:22 – digsi 5: Main protection is over current protection for railways..they adopt very inverse in the downstream for relay coordination we use same curve

10/etap training, 19:44 – digsi 5: In earth fault make voltage less in one phase
10/etap training, 19:44 – digsi 4: Your test will fail because you inject a healthy phases voltage, that’s mean there is no zero sequence voltage which needed to operate the relay
You should simulate a real fault , if an earth fault happens to phase A the voltage of this phase will drop to a low value

19etap training, 17:43 – digsi 5: In open condition AR should block
19etap training, 17:45 – digsi 5: It was in close position and I trip the CB with the relay on 21Z1 Ph-G fault. Then CB open and the relay send a reclose command
19etap training, 17:47 – digsi 5: Which relay?
19etap training, 17:48 – digsi 5: Did you check the outputs which are getting high on single phase trip
19etap training, 17:51 – digsi 5: NR PCS 931. I have checked it very well because the test kit show the duration of the trip. About 0.038s
19etap training, 17:53 – digsi 5: No other outputs are getting high?
19etap training, 17:53 – digsi 5: Yes
19etap training, 17:55 – digsi 5: Disable TOR function and then check
19etap training, 17:56 – digsi 5: TOR?
19etap training, 18:16 – digsi 5: Trip on reclose function which is there in every numerical relay
19etap training, 18:17 – digsi 5: Disable this function and then check the autoreclose
19etap training, 18:20 – digsi 5: Correct cb state must be provided for the AR relay/21 for AR to work. As I understand AR will work if the CB is open, not when it is closed, along with other interlock conditions.
19etap training, 18:22 – digsi 5: The problem is that the CB is reclosing and trip back immediately
19etap training, 18:23 – digsi 5: Which means some trip signal is tripping it.. its not the ar logic which is at fault.
19etap training, 18:23 – digsi 4: This message was deleted
19etap training, 18:24 – digsi 5: You need to remove the particular phase’s trip input to the single phase trip relay and then try a reclosing function test..
19etap training, 18:25 – digsi 5: If it works, you are going to find out which relay keeps issuing the trip positive to the 1 phase trip relay.
19etap training, 18:29 – digsi 5: If you reclose the CB from AR function of the the relay the CB close and remains. If there is an output that is high it should not stay
19etap training, 18:31 – digsi 5: That’s the logic.
19etap training, 18:32 – digsi 5: The problem happens only when I trip the CB from Close to open and back to close?
19etap training, 18:32 – digsi 5 “: You can check also timer on CB for pole dicrepancy..sometime you need delay more for reclose test.
19etap training, 18:35 – digsi 5: This is where I have doubt really.
19etap training, 18:38 – digsi 5: That s a basic check .. make sure that the dead time is not more than the reclaim time & PD time. Even though as per your description its not what trips the CB on reclosing…
19etap training, 18:41 – digsi 5 “: Please check this one..
Adjust timer on cb..after that reclose succesfully signal comming.😁
19etap training, 18:42 – digsi 5: If its a new cb, after conducting the cB closing timing test, set the deadtime above the closing time of cb too..
19etap training, 18:47 – digsi 5: it’s a new CB
19etap training, 18:47 – digsi 5: Normally, the closing time is 100msec and dead time is set as 1sec. Remove other 2 phases trip relays and then apply singlephase fault with one trip relay. Check if AR works
19etap training, 18:48 – digsi 5: Keep one trip relay in circuit with other trip relays drawn out
19etap training, 18:48 – digsi 5: Suppose you apply Red phase fault, keep red phase trip relay in circuit
19etap training, 18:49 – digsi 5: If others are there definitely it will trip the CB on 3Ph
19etap training, 18:50 – digsi 5: That’s what we are doing
19etap training, 18:50 – digsi 5: No, I’m saying you apply Red phase to earth fault using testing kit and keep Red phase trip relay in circuit
19etap training, 18:50 – digsi 5: Ok
19etap training, 18:51 – digsi 5: Have you checked that Breaker is closing on Single phase fault AR and then tripping
19etap training, 18:51 – digsi 5: If others are active the relay will show TrpA, TrpB and TrpC
19etap training, 18:52 – digsi 5:
19etap training, 18:52 – digsi 5: Thats what he says.. its closing on ar, but again tripping on single phase trip relay..
19etap training, 18:52 – digsi 5: And later due to PD timer, remaining phases trip too
19etap training, 18:52 – digsi 5: Yes
19etap training, 18:57 – digsi 5: You said that it’s again tripping on Trip relay. Check the Auxiliary contact 52A of circuit breaker which is in series with the trip coil. This contact can malfunction. This contact is meant to break DC circuit of Trip relay
19etap training, 18:57 – digsi 5: If trip relay remains in energised state it can again trip the breaker

19etap training, 18:58 – digsi 5: This message was deleted
19etap training, 18:58 – digsi 5: Are you using trip relay NC contact in closing circuit of breaker?

19etap training, 19:02 – digsi 5: This would not lead to successful Autorecloser.
19etap training, 19:02 – digsi 5: If the CB aux switch s faulty and a trip signal persists, the TC will get burned out.
19etap training, 19:03 – digsi 5: Mybad.. you are right
19etap training, 19:04 – digsi 5: Yes, trip coil can burn
19etap training, 19:05 – digsi 5: But I don’t find any other reason. I think they need to check trip coil resistance too,
19etap training, 19:05 – digsi 5: As the coil has not burned, its not the CB aux switch that s causing the issue..
19etap training, 19:09 – digsi 5: Can we extract fault waveform, I mean one more thing needs to be checked: testing kit needs to stop injecting fault after first trip, is it being ensured.
19etap training, 19:10 – digsi 5: Correct! And if the kit feedback point of the trip is correct..
19etap training, 19:11 – digsi 5: Yes I confirmed it. It shows 0.038s
19etap training, 19:11 – digsi 5: If you remove feedback the test kit continues
19etap training, 19:14 – digsi 5: Check the Programming logic of the relay, may be Autoreclose digital output signal may have been connected to the trip output contact of Relay
19etap training, 19:16 – digsi 5: Check the PSL or configuration of Distance relay
