21/abb, 17:53 – digsi 5: Sir I really dont know what to do?
21/abb, 17:55 – digsi 5: This message was deleted
21/abb, 17:56 – digsi 5: Does the CT ratio setting in relay already correct?Does secondary CT connect proper?
21/abb, 17:57 – digsi 5: The amperes showing at analoge meter are correct
21/abb, 17:57 – digsi 5: Your relay reading is not correct, and your Ip shall be same as I>
21/abb, 17:58 – digsi 5: Make sure that I is the secondary setting
21/abb, 17:59 – digsi 5: How i make it secondary?Isn’t it pre defined in device?
21/abb, 17:59 – digsi 5: I think follow my setting is better, and what is your Transformer capacity ?
21/abb, 17:59 – digsi 5: 20/26MVA
21/abb, 17:59 – digsi 5: Z%?
21/abb, 18:00 – digsi 5: Incoming
21/abb, 18:00 – digsi 5: Don’t know about Z
21/abb, 18:01 – digsi 5: Out going
21/abb, 18:01 – digsi 5: I think you better check the setting with other outgoing feeders and make same vale as those feeder, is the best solution
21/abb, 18:01 – digsi 5: Combined load is on this feeder
21/abb, 18:02 – digsi 5: Other settings are same as it is
21/abb, 18:05 – digsi 5: Okay,
21/abb, 18:05 – digsi 5: You know setting the protective Relay is not just put the value but to understand the network wit single line diagram with experience of tripping.
21/abb, 18:06 – digsi 5: Before play with tripping setting Please make sure the meter of the relay should be correct.
21/abb, 18:06 – digsi 5: 1st to know is single line diagram of network. 2nd is the upstream value to make good coordination. 3rd is to understand the setting value.
21/abb, 18:31 – digsi 5: You go to System day for outing the primary or secondary parameters
21/abb, 18:31 – digsi 5: System setting

22/abb, 05:32 – digsi 5″: Good morning, please how do I change the time delay setting on an ABB RET670?
22/abb, 05:32 – digsi 5″: Its currently on definite time but I want to change it to IDMT.
22/abb, 05:32 – digsi 5″: Thanks.
22/abb, 08:28 – digsi 5: Sir I checked the SLD what is upstream value? From where i search / set that value
22/abb, 10:13 – digsi 5: IMG-20200321-WA0012.jpg (file attached)


22/abb, 10:13 – digsi 5: It indicated 4th (indication) System overloaded
22/abb, 13:38 – digsi 5: As I know Your upstream setting is the setting in the incoming feeder (do you know that?) then check the Relay at that incoming feeder. Because your setting feeder is the outgoing feeder

22/abb, 13:45 – digsi 5: IMG-20200326-WA0006.jpg (file attached)


22/abb, 13:47 – digsi 5: We haven’t this software to draw SLD
22/abb, 13:47 – digsi 5: How can i know that? 😑
22/abb, 13:47 – digsi 5: Sir
22/abb, 13:47 – digsi 5: Show me your SLD I will tell you where is your up stream
22/abb, 13:50 – digsi 5: I will send u by handmade SLD (very simple) Coz i dont have software
22/abb, 13:50 – digsi 5: Yes just simple no need software.
22/abb, 13:51 – digsi 5: Before make setting at lease you need SLD from your utility. If you just first time in setting Relay, you need to learn more.
23/abb, 09:38 -digsi 5: Anyone knows Three phasee Energy measurement setting in REC670 Relay.
Energy is not increasing with hour in REC 670 measurement.
23/abb, 11:46 – digsi 5: Anyone Help me with,I am testing communication between
Central unit and bay unit ,7SS52xx bus bar prt relays, I am not been able to setup the communication ?

10abb, 08:23 – digsi 5: Guys,
D10abb, 08:38 – digsi 5: Yes, if & when necessary.
10abb, 08:39 – digsi 5: My bad, * Yes, if & when absolutely necessary.
10abb, 08:45 – digsi 5: Any one have exposure with schneider ecostruxure
10abb, 08:47 – digsi 5: I am led to believe that relay interrogations are reserved for essential and critical services, eg. hospitals, frozen foods packaging etc. Non essential and all new project related activities (unless critical) have been dropped.
10abb, 08:58 – digsi 5: Have Implement it?
10abb, 09:05 – digsi 5: We already had remote interrogation capabilities for all relays on the network via respective softwares SEL AcSELerator, exercise, DIGSI4 etc. during normal operations. It’s now a bit more stringent and reserved only for circuits deemed critical/essential.
10abb, 09:05 – digsi 5: ~exercise~ enervista
10abb, 09:06 – digsi 5: By using LAN?
10abb, 09:07 – digsi 5: So your relay already have the IP address, which has regulated by your team?
10abb, 09:07 – digsi 5: WAN. Wide Area Network. But I won’t be able to dwell too deep on this.
10abb, 09:07 – digsi 5: Oh Yes.
10abb, 09:08 – digsi 5: How about the security issue? Maybe cyberattack? What is your mitigation?
10abb, 09:12 – digsi 5: Hmm…Now we are getting a bit deeper, and into areas which I think I won’t be able to comment on for obvious reasons.
All I am allowed to say is there are firewalls in place to say the least. All commands sent over the network are encrypted.
10abb, 09:12 – digsi 5: 😊
10abb, 09:19 – digsi 5: 😅actually, i also want to implement it soon,
But we are (too) worry about security issues…
10abb, 09:19 – digsi 5: But, thanks for your general information😄👍🏻
10abb, 10:08 – digsi 5: Thanks Hikmah🙏🏽
10abb, 10:08 – digsi 5: Stay safe.

Registration Link :- https://go.schneider-electric.com/IN_202004-SE-Learning-Week_Session5-LP.html?
15abb, 10:59 – digsi 5: Could any one join ☝🏻 above Schneider webinar last day? Today’s topic: Subsation Automation.
I couldn’t join the webinar, after the registration, the link from email again landing on the same registration page.
15abb, 13:05 – digsi 5: Why generator differential protection is percentage wise?
15abb, 13:07 – digsi 5: To add stability for external faults and CT saturation errors.
15abb, 13:08 – digsi 5 “: Any training curse of protection…?🤔
15abb, 13:09 – digsi 5: Why it called as in percentage
15abb, 13:10 -digsi 5a: It’s not curse. It’s course Sir.
15abb, 13:11 -digsi 5: In relay we have two coil one is restain coil and one more operating coil
15abb, 13:12 -digsi 5: The low impedance relay will work according above principal
15abb, 13:12 -digsi 5: [14/04, 11:17 pm] Priyank: Hi… there’s one question that what impacts the life of CB more, high intensity faults or more number of operations under faults, over a span of say few years ?
[14/04, 11:19 pm] Priyank: I am asking this because settings of relay for 11 kV incomer CBs for a 25 MVA 66/11 KVA power transformer is being proposed to be reduced further.
15abb, 13:12 – digsi 5″: Because the relay stages is set to a certain calculated percentages i.e stage 1 is 15% stage 2 or high stage set to 70% etc.
15abb, 13:14 -digsi 5: It’s not like that
15abb, 13:14 – digsi 5 “: 😅
15abb, 13:20 – digsi 5″: I’ve mentioned a general overview not going one depth over errors, Fault calculation etc bro
15abb, 13:21 -digsi 5: Ok

16abb, 10:09 – digsi 5:
16abb, 12:40 -digsi 5: What is I^2t protection LSIG ?what will be the impact ?
16abb, 12:43 -digsi 5″: Thermal overload
16abb, 12:43 – digsi 5: its thermal over load protection, LSIG stands for long short , instantaneous and ground fault characteristics
16abb, 12:45 -digsi 5: Ya I knew this..there is option in I^2t protection on/off..if on means what will be the impact ?
16abb, 12:46 – digsi 5: what is the application? and which realy? is it feeder protection
16abb, 12:46 -digsi 5: For motor protection only we need enable this I^2 t..correct ?
16abb, 12:47 – digsi 5: LV motor ?
16abb, 12:47 – digsi 5: thermal over load is used in all protection generators, transformers, transmission lines also in motors.
16abb, 12:47 -digsi 5: It’s CB inbuilt micro logic 6.0
16abb, 12:48 – digsi 5: Masterpact Schneider right?
16abb, 12:48 -digsi 5: Ya
16abb, 12:49 – digsi 5: What is the rated power?
16abb, 12:50 -digsi 5: 5K
16abb, 12:50 – digsi 5: if this breaker is used as incomer in Motor control center or LV distribution board, there is no need to enable this.
16abb, 12:51 – digsi 5: in an individual appliction, ie breaker delicately use for motor switching, its better on this function and check for the applicable char with motor manaul
16abb, 12:54 -digsi 5: Ok..
16abb, 12:55 -digsi 5: If breaker used for UPS power up???
16abb, 12:56 – digsi 5: Think so, i2t on – will follow IDMT char and off will follow DMT char
Even I2t – on enabled and fault current more than 10 times then will follow DMT rather than IDMT
16abb, 12:56 – digsi 5: Yep
16abb, 13:03 -digsi 5: Thank you team
23abb, 13:45 -digsi 5″: Have anyone worked on protection and control panels for PST – Phase Shifting Transformers
23abb, 19:46 -digsi 5: Any one have design report for LV panel and distribution as per IEC 61439
23abb, 19:55 – digsi 5: Plz also mail me at royniraj97@gmail.com
23abb, 20:03 -digsi 5: Do you have report?
24abb, 03:23 – digsi 5: What’s your question?
25abb, 23:28 – digsi 5:25abb, 23:29 – digsi 5: arabic
02/abb, 12:32 -digsi 5″: What type of protections are used for phase shifting Transformers?
02/abb, 12:34 -digsi 5″: In normal Transformers we have vector group compensation. Since the vector of phase shifting Transformers keeps changing, how we employ differential protection for it ?
02/abb, 14:01 – digsi 5: https://youtu.be/ofPuICEpSVI
02/abb, 14:01 – digsi 5: watch my first Youtube video regarding CT Testing and support
02/abb, 14:04 – digsi 5: Vector group / phase shifting transformer keeps changing?
32/abb, 14:05 – digsi 5: Wait,
its talk about power transformer or instrument transformer?😅
02/abb, 14:39 – digsi 5: Refer IEC/IEEE 60076-57-1202-2016 or IEC/IEEE 60076-57-1202:2017 which describes protection arrangements for PST.
02/abb, 15:07 -digsi 5″: I mean, phase angle keeps changing in PST as per transmission requirement. Vector group will not change
02/abb, 15:07 -digsi 5″: Thank you for the information
03/abb, 02:57 -digsi 5 “: Waiting for this message
05/abb, 09:41 – digsi 5: Hi..!
07/abb, 21:46 – Elec Engg: Welcome all new friends🙏🙏🌸🌸
07/abb, 21:47 -digsi 5: Thank you sir
07/abb, 21:55 – digsi 5: Thanks sir
07/abb, 22:01 -digsi 5: Thanks sir

08/abb, 16:25 – digsi 5: How can i increase ampere
08/abb, 16:26 – digsi 5:
08/abb, 16:37 -digsi 5: i hope every one is ok?
can any one help me to discuss the ferroresonance that may occur to medium voltage potential transformer?
08/abb, 16:41 – digsi 5: It’s a stochastic phenomenon that occurs ultimately results in the destruction of potential transformers (particularly wound type), it doesn’t matter if it is low, medium or high voltage.
08/abb, 16:43 -digsi 5: what does you mean by stochastic? it has no rule?
08/abb, 16:45 – digsi 5: IMG-20200510-WA0016.jpg (file attached)
08/abb, 16:48 – digsi 5: Stochastic in this context means, just because the conditions are favourable for ferroresonance to occur, there is no guarantee that it will occur and vice versa, which is what makes it one of the most dreaded electrical phenomenon, a headache for electrical engineers.
08/abb, 16:49 -digsi 5: can you support me with technical guide for this phenomenon and how to protect VT from it
08/abb, 16:50 -digsi 5: thanks in advance
08/abb, 16:50 – digsi 5: You’ll now have to sign up for paid service to get more replies. First 2 queries only free🙂.
08/abb, 16:50 – digsi 5: Just kidding.
08/abb, 16:50 -digsi 5: You need damping resistors
08/abb, 16:51 -digsi 5: on star or delta connections?
08/abb, 16:52 – digsi 5: Let me dig up some of my notes and let’s have a chat in a bit.
08/abb, 16:52 -digsi 5: What is your system grounding?
08/abb, 16:59 -digsi 5: grounding through low resistane
08/abb, 16:59 -digsi 5: resistance
08/abb, 16:59 – digsi 5: This message was deleted
08/abb, 17:00 -digsi 5: It should be connected across broken delta
08/abb, 17:01 -digsi 5: if i have not
08/abb, 17:01 -digsi 5: Make broken Delta connection of VT and connect the damping resistor
08/abb, 17:02 -digsi 5: If not size the suitable resistor and connect it in star fashion
08/abb, 17:02 -digsi 5: IMG-20200510-WA0015.jpg (file attached)
08/abb, 17:03 -digsi 5: In the picture two resistor in series are shown. If you have the correct resistor rating, you can connect a single resistor
08/abb, 17:04 -digsi 5: what about VT burden?
08/abb, 17:05 -digsi 5: How does equipment in a substation works? Such as circuit breaker, battery charger, protection relay & switchgear. And how are they related
08/abb, 17:08 – digsi 5: Ya it relly is conected to 11kv v.c.b
08/abb, 17:08 – digsi 5: And it is controlling total refuse power of a feeder
08/abb, 17:09 – digsi 5: Reduse
08/abb, 17:09 -digsi 5: IMG-20200510-WA0014.jpg (file attached)
08/abb, 17:09 – digsi 5: When the feeder capacity gone high then the relly is not support
08/abb, 17:12 -digsi 5: relly mean protection relay?
08/abb, 17:12 – digsi 5: Ys
08/abb, 17:14 – digsi 5: Then current is going 73amp system gone trip how can I increase amp value
08/abb, 17:14 -digsi 5: You have to size the resistor so that VT does not get overloaded
08/abb, 17:15 -digsi 5: Generally less than 50%
08/abb, 17:15 – digsi 5: Guys there are two conversations going on simultaneously and it’s totally confusing.
08/abb, 17:15 – digsi 5: Ys
08/abb, 17:16 – digsi 5: It’s like jumping between 2 movie screens.
08/abb, 17:17 – digsi 5: Mihir, I think what you mean is to increase your pick up setting, so that when your feeder load capacity increases the relay does not trip in load?
08/abb, 17:18 – digsi 5: No sir I want how to increase load capisity in relly
08/abb, 17:19 – digsi 5: Load capacity in relay??
08/abb, 17:19 – digsi 5: Because feeder stops as soon as the load in the feeder is high
08/abb, 17:20 – digsi 5: What do you mean feeder stops?
08/abb, 17:20 – digsi 5: How to set up in Rally when we have to give more load
08/abb, 17:20 – digsi 5: Mihir, first things first, please frame your questions properly.
08/abb, 17:21 – digsi 5: I can’t speak for others, but I am finding it very difficult in understanding what it is you’re seeking.
08/abb, 17:22 – digsi 5: You want the relay to not operate when more current is going through the feeder. Is that correct?
08/abb, 17:22 – digsi 5: How to increase current carrying capacity in Sir Rally
08/abb, 17:23 – digsi 5: Ys
08/abb, 17:25 – digsi 5: You can not increase current carrying capacity in relay. What you need to do is to increase your pick up setting.
08/abb, 17:25 – digsi 5: Ys ys
08/abb, 17:25 – digsi 5: What characteristic curve are you using?
08/abb, 17:25 – digsi 5: 100/200/400
08/abb, 17:26 – digsi 5: That is the CT primary ratios you have mentioned.
08/abb, 17:26 – digsi 5: Ys
08/abb, 17:27 – digsi 5: Characteristic curve will be given by motor manufacturer… Usually C type or so, plz check in relay Mihir
08/abb, 17:28 – digsi 5: Mihir, you need to read your relay manual. Please read up on what a SI curve is to start with.

08/abb, 17:30 – digsi 5: Not clear, but I think it’z a SIEMENS Argus 7sr which you’ll find on their website.
08/abb, 17:30 – digsi 5: Thanks sor
08/abb, 17:30 – digsi 5: Sir
08/abb, 17:32 – digsi 5: Mihir, always make it a point to type slowly and try doing a spell check please, that way you will always command respect from your peers especially in a group like this where you have people from all over the world.
08/abb, 17:33 – digsi 5: Thanks sir
08/abb, 17:33 – digsi 5: Just a word of advice from a senior to yourself. I am here to help, and not to find fault with anybody.
08/abb, 17:34 – digsi 5: That’s better, see you’ve typed the words correctly
09/abb, 01:29 -digsi 5″: IMG-20200510-WA0010.jpg (file attached)09/abb, 01:29 -digsi 5″: IMG-20200510-WA0009.jpg (file attached)


09/abb, 01:29 -digsi 5″: The relay is in TEST MODE and I would like to forcing an overcurrent function but I can’t

9/abb, 01:33 -digsi 5″: IMG-20200510-WA0011.jpg (file attached)
Someone know how to connect this block?
09/abb, 02:02 – digsi 5: Sorry Robert, not very familiar with the Continental European relays. I am guessing this is a screen grab of PCM600 for an ABB relay? I know, this is not helpful, but have you tried the manual? What does it recommend? If that fails, perhaps speaking to ABB Troubleshooting Call Centre should help?
09/abb, 02:18 -digsi 5″: Thanks a lot Jairam I’ll try with the manual
09/abb, 02:18 -digsi 5″: I’ll check it

13/abb, 03:58 – digsi 5: Have you import respective relay filter for that.
13/abb, 04:39 -digsi 5: Sorted now, i used the PTL template and used import relay settings option instead of just import option. All graphs showing now.
13/abb, 15:16 – digsi 5: Muhammad Khalid Anwar: Which relay

Guys, on the ABB PCM600, everytime I click on PCM600,I get a “SQL Server instance not found error”. Trying to resolve this as per a YouTube video instruction by going to “Windows Services” and trying to start the SQL Server (PCMSERVER2014) has proved futile with an Error:1069.
19/abb, 05:46 – digsi 5: Have any of you faced this issue, would be helpful if you could let me know how you overcame this issue, without having to uninstall and reinstall PCM600, and in the process I am losing all projects and have start from scratch. Just so you know, I don’t use PCM600 on a regular basis. Look forward to hearing back from all experts out there.
19/abb, 07:25 -digsi 5: Hi
19/abb, 07:30 – digsi 5: Mani, thanks for your reply, but I have already tried that as described in my earlier post. When I right click on PCMSERVER2014 and select start/restart, it comes up with Windows error: 1069.
19/abb, 07:31 – digsi 5: So I am stuck at step no. 3 in your post. I can’t get to 4.
19/abb, 07:32 -digsi 5: Ok I will check
19/abb, 07:33 – digsi 5: Hi, installed before ?
19/abb, 07:35 – digsi 5: Usually while installing PCM 600 , we have to select SQL verbose data base option.
19/abb, 07:36 – digsi 5: Yes, this happened a few days after I installed PCM600 for first time, and I have had to uninstall & reinstall PCM600 every time this error occurs. Not sure, what is going on.
19/abb, 07:36 – digsi 5: Yes, I believe I did that. What is this verbose option, could you please enlighten?
19/abb, 07:37 – digsi 5: If you want I can make a short video of how this error is being generated, just to give you guys an idea of the sequence.
19/abb, 07:38 – digsi 5: It’s kinda server based software operation
19/abb, 07:39 – digsi 5: Hope so you have .pcmp / .pcmi file
19/abb, 07:40 – digsi 5: If it’s so then you can uninstall and try to instal once again in stable network connection
19/abb, 07:41 – digsi 5: I don’t mind uninstalling & re-installing, but I am losing all projects I created & I have to start all over again. This is my concern.
19/abb, 07:42 – digsi 5: What file is this my friend?
19/abb, 07:42 – digsi 5: Project file which you have / developed
19/abb, 07:43 – digsi 5: Ah! So I need to search for the project file with this extension & reload once I uninstall & reinstall PCM600.
19/abb, 07:43 – digsi 5: Can you pls check PCMSERVER 2014 is started in programmes task manager
19/abb, 07:45 – digsi 5: Yes , if you have that in your system
19/abb, 07:45 – digsi 5: Can you tell me how I can check that pls. I know it may be a silly question, but taking no chances and not assuming anything.
19/abb, 07:45 -digsi 5: For Windows error
19/abb, 07:45 – digsi 5: I’ll look for that keep you posted.
19/abb, 07:47 – digsi 5: Check in this
19/abb, 07:49 – digsi 5: Ok, how about you & me have a chat in say a couple of hours time? Can’t restart now as I am reprogramming a few relays. Once I have a bit quieter time, we can have a further dig in. Happy to exchange notes on this & wider protection aspects.
19/abb, 07:50 – digsi 5: Appreciate your help buddy. Keep em’ coming.
19/abb, 07:50 – digsi 5: Ok 👍

31/abb, 19:06 – digsi 5″: To change parameters in offline you have to create another project file through MLFB of the relay.
31/abb, 19:09 – digsi 5: Muhammad Khalid Anwar: Is there any issue to create impact on IEC61850 protocol, if i create file from MLFB and send to relay
31/abb, 19:10 – digsi 5: Muhammad Khalid Anwar: Basically our all relays are communicating from Siemens SCaDA servers
31/abb, 19:14 – digsi 5″: Yes, if you’re using 61850 protocol then must have to check it’s rtu files as well
31/abb, 19:20 – digsi 5: Muhammad Khalid Anwar: Its a hatic job, is there any alternate solution. Basically i have not RTU’s files

5abb, 23:54 -digsi 5: Any one have the setting of Auto recloser for micomP142
20abb, 03:56 – digsi 5: And how may I ask do you anticipate people who do not understand Arabic (which I believe is a majority) to comprehend the contents of such videos?… This is pointless.
20abb, 08:06 -digsi 5: Yes…the video appears to be good. But the language should be understandable to all for fulfilling the noble purpose of knowledge sharing…
20abb, 12:19 – digsi 5: What plant are you protecting? What are your CT ratio & characteristics?, What is the max. through fault for which you require stability, what is the minimum fault for which you require the protection to be sensitive? These are questions whose answers you need to find in order to arrive at the solution. As P642 is not inherently a high impedance relay, you will need to size a suitable series stability resistor of adequate wattage (for heat dissipation) based on your calculated Vstab. As current sensitivity can be tweaked in the relay, the use of a shunt resistor for internal faults is superfluous.
Please note, there is no one size fits all solution for any setting.
28abb, 12:18 – digsi 5: What is use of wire connecting bus bar and CT in 11kv ht switchgear
Can we charge the feeder without that wire…
28abb, 12:21 -digsi 5: To create equal potential between bus bar and ct
28abb, 12:21 – digsi 5: I mean CT equalizing wire
28abb, 12:22 -digsi 5: U can charge without it but will get humming sound and after few years ct may get damaged due to potential difference
28abb, 12:22 -digsi 5: Yes
28abb, 12:22 – digsi 5: The feeder megger value with that wire is zero…
28abb, 12:22 – digsi 5: Without that wire is 500 mohm
28abb, 12:23 – digsi 5: Is the CT faulty…
28abb, 12:23 – digsi 5: Is there any leakage throgh ct insulation??
28abb, 12:23 -digsi 5: May be
28abb, 12:24 -digsi 5: That wire is connected to resin cast and no where linked to primary or sec terminal
28abb, 12:24 – digsi 5: Yes.. panel megger values coming zero due to moisture in the panel, so all the componants removed and cleaned… But facing the above issue with equalizing wire
28abb, 12:24 – digsi 5: S
28abb, 12:25 -digsi 5: If u have spare ct better change it or remove to wire and charge in case of emergency supply restorarion
28abb, 12:27 – digsi 5: All three phases same position
28abb, 12:28 -digsi 5: If u want to check.. Better apply 440v supply accross it and check the phase to gnd voltage
28abb, 12:29 -digsi 5: All 3 phase damaged at same instance is impractical
28abb, 12:29 -digsi 5: May be ur testing method may be wrong
28abb, 12:29 -digsi 5: Test IR from the wire to ct base plate
28abb, 12:30 – digsi 5: Panel filled with chemical fumes…
28abb, 12:30 – digsi 5: So that moisture formed… Thinking may be failed due to moisture in the panel
28abb, 12:30 -digsi 5: Then u need to clean the ct outer surface thoroughly until u get shine
28abb, 12:31 – digsi 5: Ok
28abb, 12:31 -digsi 5: Remove the cts keep it in hot sun for 2 hrs and retest
28abb, 12:31 -digsi 5: If possible repaint it
28abb, 12:31 -digsi 5: We do have lot of cts in charged conditions without the wire connected from years together

30abb, 22:57 -digsi 5: Double operation means what? Why it’s required?
31abb, 00:45 – digsi 5: In what context?
31abb, 00:47 -digsi 5: It’s have common interlock on 11kV board
31abb, 00:47 -digsi 5: And also 132kV GIS
31abb, 02:50 – digsi 5: That still doesn’t convey anything to me. Double operation of what, in an interlock?
31abb, 09:45 – digsi 5: Double operation prevention means, at a time have to perform one operation. Suppose in one Bay , you are trying to close breaker in one breaker and parallel some one trying to close earth switch on same time for another bay. May chances for accident without proper communication between them. In order to avoid this , have to set up Double operation
31abb, 10:10 – digsi 5: Make sense.
01/abb, 02:07 – digsi 5: For that you have to implement electrical or logic interlockings

The above is extract from a protection function in REF615. Normally we measure RMS values for the protection right ? Do anyone know where other types of quantities like DFT and Peak values are used ?
21abb, 11:54 – : Peak values can be used for overvoltage detection such as capacitor banks which can give fundamental and other non 50 or 60 hz signals from the system
21abb, 11:55 – digsi 5: Related to insulation rating and heating effects
21abb, 11:56 – digsi 5: If DFT is discrete fourier transform then its fundamental detection used for protection

15abb, 15:48 – digsi 5: What may the reasons if transformer tripping on differenrial…
15abb, 15:50 – digsi 5″: You have to test all captured equipment in the differential zone.
15abb, 15:51 – digsi 5″: Including the transformer itself.
15abb, 15:51 -digsi 5: There is fault or Mal operation ?
15abb, 15:51 – digsi 5″: Is it a new installation?
15abb, 15:51 – digsi 5″: For how long has it been in service?
15abb, 15:51 – digsi 5: Suspecting malfunction.. How can i confirm
15abb, 15:52 – digsi 5″: Do stability and sensitivity test.
15abb, 15:52 – digsi 5: For last 1 month after overhaul
15abb, 15:52 – digsi 5: Yeah…usually if we test relay first and found fault inside itself, most of your problem is resolved, otherwise u have to test CT’s and trafo too
15abb, 15:56 – digsi 5: It was resetted and charged again… Values are same as normal
15abb, 15:57 – digsi 5:
15abb, 15:58 – digsi 5: Can any body say.. How it tripped
15abb, 15:58 – digsi 5: Id min is 0.1 of I base
15abb, 15:59 – digsi 5: W1, w2 are fault magnitudes, relay RET670
15abb, 16:03 -digsi 5: Id min is normally 0.2 or 0.3 PU.
15abb, 16:04 – digsi 5″: First of all you have to check fault record from the differential relay, also observe and check physical objects near Trafo i.e hot spots/animals/bird/wires etc then closely monitored the FR from the relay
15abb, 16:05 – digsi 5″: If everything found satisfactory then you would have to go for transformer testing
15abb, 16:08 – digsi 5: Differential should not act for external faults
15abb, 16:09 – digsi 5″: Of course yes, it’s about checking all the equipments in the differential zone
15abb, 16:10 – digsi 5: Ok
15abb, 16:15 -digsi 5: Ct saturation,wrong settings,
15abb, 16:15 – digsi 5: Ok
15abb, 16:43 – digsi 5″: Finally, do an insulation resistance test on all equipment captured within the differential zone if nothing wrong is found during inspection.
15abb, 16:45 – digsi 5″: Another thing that can cause frequent 87T operation is if your magnetization current (during trf ratio test) is high. It tells you there is an internal problem
15abb, 16:45 – digsi 5″: It won’t trip during energization but as load increases, it will trip.
15abb, 16:46 – digsi 5″: Good luck.
16abb, 19:35 – digsi 5: The signal aren’t pure sinusoidal?Are there any loss termination of current circuits?
22abb, 13:55 – digsi 5:

24abb, 18:34 -digsi 5:
24abb, 18:34 -digsi 5: Anyone know why we are using this diode and what is uses
24abb, 19:04 – digsi 5: There is two source two avoid back feeding this diodes are using
24abb, 19:05 – digsi 5: Both source is change over by relay during transient time this ll protect from back feeding
25abb, 03:39 -digsi 5: Anyone knows if we can supervise 2 separare trip circuits using a single TCS relay MVAX31 ?
25abb, 03:46 – digsi 5: Don’t think so, as far as I know, you’ll need an MVAX31 per trip circuit. It’s not too expensive a relay.🙂
25abb, 03:46 -digsi 5: 👍
25abb, 10:47 -digsi 5: Any one have omicron template file for out of step protection in simens generator relay

25abb, 13:24 -digsi 5″: The physical circuit or in the pcm?
25abb, 13:25 -digsi 5″: I have desconected trip
25abb, 13:25 – digsi 5: What was assigned to that led?
25abb, 13:25 -digsi 5″: Supervision
25abb, 13:26 – digsi 5: Of what?
25abb, 13:27 – digsi 5: Robert if that is Trip circuit supervision, and you have disconnected (trip circuit is open), then the LED will glow as indicated.
25abb, 13:28 -digsi 5″: Just this
25abb, 13:28 – digsi 5″: That’s because there’s a missing (-ve) from the trip coil being supervised.
25abb, 13:28 – digsi 5″: Hope your mcbs are on.
25abb, 13:28 -digsi 5″: Thanks friends, that was it
25abb, 13:28 – digsi 5: Good
25abb, 13:29 – digsi 5: Don’t worry your LED did as it was expected (as soon as it detected a break in your trip circuit) 😊

07abb, 14:34 -digsi 5:
07abb, 14:36 -digsi 5″: We are commissioning PCS-985 Transformer Protection Relay… NR Electric … For 660MW Coal fired power plant.
07abb, 14:37 – digsi 5″: Okay
07abb, 14:48 – digsi 5: 1.Overcurrent (Highset for HV bushing faults).
07abb, 14:50 – digsi 5: What is your transformer winding configuration?
07abb, 15:34 -digsi 5″: Yes.. Stand by earth fault
07abb, 15:38 – digsi 5: Is this a generator transformer ie power is being exported out thro’the 500kV trafo. bushings?
07abb, 15:41 -digsi 5″: This is a start up & standby Transformer..for engerization of the auxiliaries before the power been generated..
We have two transformers.. One is Generator transformer 22/500KV..
The second is startup and stand by transformer
07abb, 15:44 – digsi 5: Ok, so you’re generating at 22kV and exporting out at 500kV. You are feeding 11kV auxiliaries thro’ 11/500kV trafo.
07abb, 15:45 -digsi 5″: Exactly Sir
07abb, 15:46 – digsi 5: Ok, because of the power flow, I think the higset for bushing faults that I mentioned may offer little benefit in your case.
07abb, 15:47 -digsi 5″: Sir, what You will recommend for this
07abb, 15:47 – digsi 5: This normally works for grid transformers deep within the transmission side where power flow is from HV to LV say 500 kV to 220 or 132kV.
07abb, 15:49 -digsi 5″: Sir, is ours protection scheme is OK?
07abb, 15:51 – digsi 5: I think you are pretty much covered. The highset OC is normally useful to detect for bushing faults on the HV side and remains stable for LV side faults provided the power flow is from HV to LV.
07abb, 15:52 – digsi 5: Can you send me a quick snap shot of your SLD? I just want to see how the transformers are connected and the earthings.
07abb, 15:57 -digsi 5″: OK. Sir…
07abb, 16:03 – digsi 5: What about over fluxing Protection…
07abb, 16:04 – digsi 5: Spot on, definitely needed for general Trafos. 👏🏼👏🏼
07abb, 16:04 – digsi 5: Thanks Amaresh.
07abb, 16:05 -digsi 5″: Sir, this is not covered in the relay
07abb, 16:05 – digsi 5: *generator Trafos.
07abb, 16:06 -digsi 5″: No. Sir.. Start up and stand by transformer
07abb, 16:07 – digsi 5: Means a different relay is used for V/F
07abb, 16:07 – digsi 5: 🤝🙏
07abb, 16:08 -digsi 5″: Yes..
08abb, 00:34 – digsi 5″: Good evening – I am trying to download now but I can only see PCM600 2.10
08abb, 00:34 – digsi 5″: Is that okay?

26abb, 12:03 – digsi 5: Ratio of setting current to rated nominal current
26abb, 12:04 – digsi 5: > means low set >> means high set
26abb, 12:04 – digsi 5:
26abb, 12:04 – digsi 5: Usually this is the approach
26abb, 12:04 – digsi 5: Ct ratio is 100/5
26abb, 12:04 – digsi 5: This message was deleted
26abb, 12:05 – digsi 5: IN = 5
26abb, 12:05 – digsi 5: My load is 15amp HT
26abb, 12:05 – digsi 5: I want to trip it at more than 15amp
26abb, 12:18 – digsi 5: Relay coordination is required
26abb, 12:18 – digsi 5: For timing
26abb, 12:19 -digsi 5: Usually this is the standard they fellow in all utility.. For 11kv they keep 500ms
26abb, 12:23 – digsi 5: Can u tell me calculation
26abb, 12:27 – digsi 5″: This is high set indicator in relays.
26abb, 12:27 – digsi 5: This is true? iN =CT ratio current
26abb, 12:27 – digsi 5: 20Amp
26abb, 12:32 – digsi 5: Not all places
26abb, 12:36 – digsi 5: High set to 6 depends on downstream load nature. Like motor or transformer. If plain fdrs then we can even go down. Better to check also with utility followed standard.
26abb, 13:56 -digsi 5: In is CT secondary 5A
26abb, 13:57 -digsi 5: I too work for public utility.. Here in South india we follow the same
26abb, 14:34 – digsi 5: Not in kseb
26abb, 14:35 -digsi 5: Even in kseb the time setting is 500 ms for 11kv
26abb, 14:36 – digsi 5: I do consultancy to kseb. We don’t use every where
26abb, 14:36 – digsi 5: Official consultant
26abb, 14:36 -digsi 5: Ok
26abb, 14:37 -digsi 5: But state utility will allow 500ms delay for 11kv level
27abb, 17:43 -digsi 5: Hello,
27abb, 18:06 – digsi 5: I need Eplan or other soft ware for electrical design dept.
Is this actual fault happened in the transformer Or this inrush current !!!??According to disturbance recorder.
31abb, 18:51 – digsi 5: Ya
31abb, 18:51 – digsi 5: Ahora estoy
31abb, 19:00 – digsi 5: Better to test relay and CT’s, even though inrush current exists it should be normal before time delay of tripping, also check voltage profile
31abb, 19:03 -digsi 5: Fault
31abb, 19:24 – digsi 5: This is a fault at phaseA -ground
31abb, 19:32 – digsi 5: If there is a wave gap present in two phases and other phase symmetry then it can be inrush
31abb, 19:40 – digsi 5: Usually, it is instant, no delay tripping for Diff protection
31abb, 19:40 – digsi 5: In rush😁
31abb, 19:41 – digsi 5: Just enable in-rush / 2nd-harm blocking for Diff Prot.
02abb, 00:27 – digsi 5: Can anyone help me how to auto reclose test in 7vk61 relay.

10abb, 19:05 -digsi 5:
10abb, 19:06 -digsi 5: Could anyone tell me what happened with the relay.
10abb, 19:17 – digsi 5: Check if the relay is connected to an SNTP Server.
10abb, 19:17 – digsi 5: Perhaps, this is why it may have failed.
10abb, 19:20 – digsi 5″: For sale
10abb, 20:52 – digsi 5″: It could be battery replacement. Further check this error code from manual.

10abb, 23:23 -digsi 5″: Hello
10abb, 23:23 -digsi 5″: I have this settings
10abb, 23:24 -digsi 5″: But you can see the trip time is not correct
10abb, 23:24 -digsi 5″: I have this relay
10abb, 23:25 -digsi 5″: Why?
10abb, 23:26 – digsi 5: What is this software ?
10abb, 23:26 -digsi 5″: Power db 11.2
10abb, 23:27 -digsi 5″: For this equipment
10abb, 23:37 -digsi 5: Is 5700A primary pickup correct?
10abb, 23:45 -digsi 5″: No it doesn’t
10abb, 23:45 -digsi 5″: CTR in the primary side is 30:5
10abb, 23:48 -digsi 5″: The differential test its Ok but the OC test does not match operating times
10abb, 23:51 -digsi 5: Isn’t primary supposed to be 1.14kA instead of 5700?
10abb, 23:54 -digsi 5″: This value is 5,7A not 5700
11abb, 19:13 -digsi 5″:
12abb, 00:34 – digsi 5: This is big. When did this happen?
12abb, 07:18 -digsi 5″: Black out occurred at 11pm on Saturday-sunday midnight to 6am morning.. the longest blackout in the history of Pakistan
12abb, 07:20 – digsi 5: It’s happening everywhere my friend, recently we had blackout in Mumbai. Anyway what is the cause? Power swing and cascades!?
12abb, 07:24 -digsi 5″: This was the country blackout.. whole the country was plunged into complete darkness..
The initial investigation reveals that I was occured to false operations by shift incharge of Guddu Power Plant that intiates the tripping of main 500KV transmission line
12abb, 07:25 -digsi 5″: Actually Power protection relaying, configuration and improper setting by the shift personal, cause the whole system into blackout
12abb, 07:26 -digsi 5″: All of the shift personals working during that shift are terminated.
12abb, 19:11 -digsi 5″: For free training webinar
14abb, 07:38 -digsi 5″:
14abb, 07:38 -digsi 5″: Hello, I have a problem with this relay, I changed the recloser batteries and after that the relay no longer wants to work, it is worth mentioning that before changing the batteries, energized with AC voltage, the relay worked well. Now it just presents this fault and doesn’t show anything on the screen, can anyone suggest something to me? Is the relay damaged?
14abb, 07:57 – digsi 5: This message was deleted
14abb, 07:58 – digsi 5: Robert’s let’s go a step or two back to find out what’s causing the issue.
14abb, 07:59 – digsi 5: You said before you changed the batteries, everything was fine. So what was the driver behind changing the recloser batteries?
14abb, 08:01 – digsi 5: Did you try rebooting the relay?
14abb, 08:03 – digsi 5: What happens if you put the old batteries again? Would it go back to the initial point, where it was working OK?
14abb, 08:05 – digsi 5: Just using the usual trouble shooting algorithm in doing a 🐠 bone analysis
14abb, 08:08 -digsi 5″: Indeed the recloser did not have a DC backup since the old batteries do not work (the relay was operating only with AC voltage), we have already tried to put the previous batteries and it does not work. Still not trying to rebooting the relay.
14abb, 14:29 -digsi 5: Anyone here used Vebko relay test set? Would appreciate feedback. Thinking about purchasing it since its doing relay tests just like omicron, plus Transformers, CTs VTs and CBs.

Above is the trip circuit for 33kV VCB board. What is the function of B6&B8(mark in circle) here?
28abb, 10:24 – digsi 5 For trip circuit supervision function
28abb, 10:29 – digsi 5 On CB off condition both input will be high. On CB on condition 1 input (b2&b4) will be high
28abb, 10:37 -digsi 5: Ok. What happen if remote trip is continuously high? Is it result continue energization of VCB trip coil or Binary input (B6/B8) prevent sending continues trip command to trip coil?
28abb, 10:43 – digsi 5 Both ip will be low during trip command.
