(हिंदी में) - 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.
