English: Part-6: Directional Over-Current Operating Region | REL670 | RET670 | 7SJ66 | 7SJ80 | RCA
Speaker information: Pankaj Kumar Jha
Chief Manager, Power Grid Corporation of India Ltd.
(Power System Engineer with more than Twelve (12) years of industrial experiences.)
In this series of videos on Over-Current and earth fault protection, we will focus on following topics:
1. Over-Current & Earth fault protection - need and basic concepts.
2. Non-Directional & Directional Over-Current & Earth fault protection.
3. Different types of IDMT Characteristics - need, settings & challenges in protection coordination.
4. Protection coordination with Over-Current & Earth fault protection relays in complex networks.
5. What is TMS? and PSM?
6. Polarization quantities in Over-Current & Earth fault protection - how to select?
7. Application of directional overcurrent & earth fault protection relays in complex networks.
8. What is RCA?, ROA? MTA? and how to determine the operating range of Directional Over-Current & Earth fault protection?
9. Implementation and protection algorithms of Directional Over-Current & Earth fault protection in all the major numerical/digital relays like REL670, 7SJ66, 7SJ80, RET670, P444, D90, NR PCS931 and NR PCS902.
10. Negative sequence based Directional Over-Current protection.
One or two videos shall be uploaded each week on the aforementioned topics. These videos shall be in both Hindi as well as English languages.
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.

Amazing videos ! very helpful !
THANKYOU SIR <3
Thank you so much sir now my concepts of IEC 61850 are clear this is a very helpful video for us 🙏
sir we dont know the fault current its beyond our reach so how can we do the setting if we dont know the fault current in real world or practical senerio
Thanks for the knowledge Sir! absolutely excellent lecture!
Nice
Sir agar 3 phase kay sath ye video banathy thu bohoth acha hotha
Bro ap itni achi videos banate they, ap ne band Q Kar dia videos banana😢
Very helpful bro
It helps me a lot sir. Thankyou very much
At 12:00 i cant see the pointer
Thankyou very much sir.. these videos are very helpful for me
mind blowing teaching
Thank you
Thank you sir
Excellent 👌
🎉 sir
Dear sir thank a lot ,one request to please make a video on micom p645 according to my drawing that I will share you , kind request please and please share your mail id.
Thank you so much great effort.
Sir please make psl on p645
Is the English version available?
Great sir ..please make more videos about schematic drawing of double main bus scheme
For all practical purposes do we need to have a distance relay at substation N?
Really Sir, great teaching.
Thank you sir for delivering this insightful electrical protection system.
My again one concept is cleared by you sir
I have checked many slope test , but you are the best...sir❤
Super lecture
Please make a video on What is add on stabilizer in Siemens siprotec differential relay
Thank u,sir
Sir I am a very big fan of you. Learnt a lot of things. Sir Please make videos on FOTS communication Online DGA communications. Thank you sir
Sir,minor correction is needed while explaining the tv chanel example, you have mentioned it as a multicast example but it should be broadcast example. Plz correct me sir, if I wrong.
how to configure frequency analog channel for DR of p632 relay ?
Nice explain sir thanks
Wonderful lectures and explanation. Thanks a lot for sharing your knowledge sir
Very nice explaination
Thanks a lot for sharing such a knowledgeable lectures
Very good explanation sir😊
Thank you so much
Thanks
Useful video thanks.,
Hindi mein banao.. Please😢😢
Hi sir Very nice explanation Please make videos on SEL & GE relays
Thank u sir ....Love u...
Thanks a lot
sir .. in one and half scheme if 89L is opened and dia is charged.. and any how if we get DT signal from other end then in this case our main and tie CB will trip or not? and also in above case.. relay will continue show fuse fail?
1. If we receive DT, Main & Tie CB will trip at our end. 2. Most of the relay will not show VTFF if settings and configuration are correct - because it will detect line dead condition.
sir vedio on network topologies
