Differential Protection is one of the most important protections for Transformers, reactors, and Bus Bar. In this video we will discuss about the testing of numerical differential protection relays using Omicron Relay Test Kit. All the concepts required for testing of differential protection will be explained in detail. This session focusses on the following aspects of differential relay testing:
1. Differential Stability Test.
2. Differential Pickup Test
3. Differential Relay Slope Test.
4. Second Harmonics Blocking.
5. Fifth Harmonics Blocking.
An incredible amount of time and effort is needed to develop high-quality video tutorials. Each video takes approximately 6-8 hours to complete which includes learning the concept myself, brainstorming creative ways to teach and explain the concepts, creating the presentations (if delivered through PPT mode), Setup of analysis software, video recording, and editing. Your support truly makes all the difference. So, please like👍🏻, comment and share this video with your friends and keep watching this channel for more such videos in future.

Really love the approach. This is the very basic of differential protection testing and also if your are using quick test template on tester. Thanks sir.
Sir please explain generator, Motor, line differential and directional Protection in detail. Transformer differential explanation is very nice 👍
Sir aap ko Mai kaise appreciate Karu uska koe varnan nhi h. I have no words for your time and value.

Aapka feedback hi kaafi hai dost…. Dhanywad
Proud to have you sir. 🙏🙏🙏🙏🙏
sir really very helpful video. Sir please aise hi ek video Micom P442 relay ka bhi banaieyega
Very helpful and informative session. Thank you.
Mashaallah please really i am also expecting and eagerly waiting for this and atlast we received correct information from correct source
After long time , Back again
Thank you so much sir......For uploading such a knowledgeable video
Thank you sir for such a great explanation👏
Very nice and a lot of helpful lecture.
Lovely session .sir kindly continue this session.
Thanks for upload after so long time
Thanks
Fruitful session Sir. Thanks Sir
Sir, Thank you so much for this video. Really very informative. Request you if you can make video on SEL 487 and their applications.
Thanks sir 👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻
Rel 670 ma zone testing ka video uplod kijiya plz sir..
Thanks a lot Kindly prepare a vedio on distance relay testing by omicron or by magger RTMS test set
Sir,Please explain ABB REL650 relay configuration commissioning

ABB REF630 also
Please bring a video on testing of REF,overfluxing,directional oc and ef
Good sir
9mva generating transformer (v group Ynd1). transformer nutral remove kardu to kuch problem hoya, up ki pass kuch tarka hay to bataye, nutral remove karke transformer chalsakti hai, any implementation,
Hello sir Can i use this relay protection software in my apple MacBook laptop or only use in windows os
Sir kindly make video for testing of High impedance busbar differentila relay 7SG1211
Please upload next video
Sir, thnks for upload this video, how you know what our demand 🙏🙏🙏🙏😆
Sir please slope ka link share kare kis vedio me hai
Sir end section 1=1×i base And end section -2=2×i base ko kya me assume Karu ya sir koe formula h . calculation ka, yaa sir settings dekh ke kaise pata Karu ke end section 1×i base or 1.5×i base hoga
Anyone please tell where we take 91 value during 2 harmonics time ...
How to decide Is2 or in your case end section 2 bias current? In your case it is 3 p.u. How can we decide it?
Sir please make a video for Why 11Kv incoming panel Y phase PT Ground in panel
Sir, 1st of all thank you for sharing your valuable knowledge.... I have one doubt , in 2nd hormonics setting shows relay will be if 2nd hormonics current goes upto 10% but in slides you say that if current is more than 10% relay will not trip and if less than 10% it will trip. Is it not contradictory? Kindly explain me sir please
Sir, will the relay trip in the highset ?
Sir differential relay ki puri commisioning ka video banao na
Sir please ek video CSD per bhi banaiye. KZread pe koi bhi CSD related video hindi me available nhi hai.🙏🙏🙏
Sir please generator rotor earthfault Or stator earthfault k upor video banadijiye
Sir REF Ka bhi theory Thoda Bata dijiey ga
Substation feasibility video
Endsection will be given customer
I have following relay data (during a practical fault & differential relay got operated) IW1A : 399
Thanks
