(हिंदी में) - Part-1: Overcurrent & Earth Fault Protection || Over Current || Definite Time || IDMT

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.

Online DGA communications.
Thank you sir

[@VipinKumar-l5n3v]

Welcome back sir. Thanks sir .

[@LIGHTNINGMINDS_PANKAJKUMARJHA]

Thank you too!

[@ganeshdhurve876]

I was waiting for your videos since a long time. Now , wait is over. Nice explanation. waiting for next videos. This topic is very important for me, because i have faced time discrimination in relays many times.

[@bharatprajapati8578]

Sir , we are waiting more videos on SCADA and IEC 61850
Thanks for uploading knowledgeable videos .

[@tanseerahmedd9159]

Welcome back sir. Kindly regular videos upload kia karen

[@LIGHTNINGMINDS_PANKAJKUMARJHA]

जी धन्यवाद । इस बार यही कोशिश रहेगी 😊

[@ranjansahu2362]

Very basic n clear consept...

[@ummeeshaalnaat]

Thank you sir we waiting for next video

[@ImranKhan-nu6xw]

Appreciate you work sir

[@shahrukhkhan4190]

Thank you thankyou so so so much sir make more videos
Aaj yeh sab jankar itna difly and easily jankar bhut bhut acha lag raha hai sir 🥲

[@LIGHTNINGMINDS_PANKAJKUMARJHA]

Thank You for your valuable feedback

[@kishanpanchariya6222]

Thank you much sir for your support as always 🙏🙏🙏

[@LIGHTNINGMINDS_PANKAJKUMARJHA]

Thank you for your patience😁

[@arghyamukherjee8583]

Plz make a video on ref protection . And plz discuss what is the meaning transient bias

[@shashankthakur1105]

👍👍👍👍👍👍👍👍

[@arunhazra1678]

Sir please make a video motor protection setting calculation from motor name plate

[@prabhatsingh5377]

Excellent work.

[@LIGHTNINGMINDS_PANKAJKUMARJHA]

Thank you

[@ranjansahu2362]

Sir consept of -ve sequence Over Current ka part cover nehe hey iss series main... So plz make video on this...

[@sisodiahemendra23]

Back to work 😊

[@LIGHTNINGMINDS_PANKAJKUMARJHA]

Hopefully 😁

[@chinmaya423]

Sir, kindly make video of implementation of auto reclosure in 132kv system in Micom 442 and SEL 311C along with equation and PSL logic.

[@oshovision-lx1jw]

Sir
Please make real time faults resolved .
At our station line tripped on master trip no fault current.
Distance shown in alstom relay mere than the length of line?

[@raj3094]

❤❤❤

[@arghyamukherjee8583]

After a long time sir. Are u well sir.

[@LIGHTNINGMINDS_PANKAJKUMARJHA]

Yes, I am not in India since may and hence it got delayed. Hopefully now I will continue to upload at least one video each week.

[@ImranKhan-nu6xw]

Kindly sir prepare digsi configuration for simens 7sj80 overcurrent earth fault relay as you have did configuration of simens distance relay 7SA22

[@LIGHTNINGMINDS_PANKAJKUMARJHA]

Ok

[@ranjansahu2362]

Sir for micom p141 also... With PSL

[@sawan1805]

Dear sir
If possible can you share me the pdf file of this presentation.
🙏please🙏

[@arunmukhiya1149]

Sir vidio are coming after to much late

[@tjjanarthananx]

Sir, pl upload video for negative sequence directional overcurrent relay... Possible pl provide your mail id sir..

[@LIGHTNINGMINDS_PANKAJKUMARJHA]

Ok, I will definitely upload video on this topic

[@cricketinformationcapsule]

Sir plz plz aap video banana ktun band kar diye hai. Plz aur protection par video bana dijiye please🙏🙏🙏🙏🙏
