Bus Bar Protection | Concepts and Applications of Low Impedance Bus Bar Differential Protection |

Speaker information: Pankaj Kumar Jha
Manager, Power Grid Corporation of India Ltd.
(Power System Engineer with more than Ten (10) years of industrial experiences.)
The fundamental concepts of bus bar protection will be discussed in this series of session. In this series we will discuss about the basic concepts of Bus Bar Protection. Difference Between High Impedance and Low Impedance Bus Bar Differential Protection. The concept of CT saturation and its effect on the performance of Bus Bar Differential Protection. High impedance bus bar differential protection calculations. Centralized and Decentralized bus bar protection schemes. Concepts of Bus Zone and Check Zone in case of bus bar differential protection schemes. At the end of this series you will learn all the fundamental concepts related with bus bar differential protection. All the sessions will be in Hindi as well as English and you may watch these sessions as per your convenience.
For better understanding of the concepts explained in this session, it is desirable that following sessions must be watched:

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.

01:45 Stabilization resistance takes care of CT saturation

[@surendrakverma555]

Very good. Thanks 🙏🙏🙏🙏🙏

[@LIGHTNINGMINDS_PANKAJKUMARJHA]

Thank You for watching.

[@ashokasahoo]

Simple and excellent presentation

[@LIGHTNINGMINDS_PANKAJKUMARJHA]

Thank You. Keep watching for more such videos in future.

[@randhircheema1642]

Nice presentation. At around 13 mins.,you mentioned CT ratio 1:1. This was confusing a bit because if CT ratio is 1:1, we cant run 10A through it. I know you used it to explain the concept. All good, thanks.

[@sohanlal-no7yp]

excellent sir

[@LIGHTNINGMINDS_PANKAJKUMARJHA]

Thanks and welcome

[@upasanaranjan1364]

Excellent Presentation and many thanks for sharing it !!!
If you can make practical video tutorial on same topic by actually taking up a real substation drawing correlating it with control schematics and showing how actually the entire thing works then it would be great enhancement to this tutorial.

[@manishprasad31]

Very good explanation 👏👏👏

[@sanjeevrana8317]

Excellent 👌👍 KUDOS

[@LIGHTNINGMINDS_PANKAJKUMARJHA]

Thank You for your valuable feedback.

09:56 fault agar line ya feeder mei hai ( bus bar ka apna fault nahi hai) toh Differential current mei koi change nahi aaega. But stabilization current hamesha Raheja kyuki wo sab feeder current ke magnitude ka sum hai

[@rupaliranaleaderdevotee]

Stabilization current Kaifi high magnitude rahega

[@wary8113]

thank you Sir.

[@shreehappe4912]

Nice explanation sir..

[@rupaliranaleaderdevotee]

01:57 for obvious reasons the impedance of relay is less than CT

[@mohammadsufiyan1365]

What kind of changes if scheme is combination of2 nos. bus sectionliser and buscoupler

[@subbiahkannan.s7272]

sir your videos are excellent.why line differential protn and its importance in power system protection.can you cover the line differential protectin

[@LIGHTNINGMINDS_PANKAJKUMARJHA]

Thank you for your valuable feedback. I will cover line differential protection shortly. Stay tuned for more updates.

[@aeerdkptcl4017]

Sir,
Please explain Bus Reactor

[@sanjeevrana8317]

Discuss vector surge relay protection, relay co-ordination chart

[@LIGHTNINGMINDS_PANKAJKUMARJHA]

OK... I will discuss these topics in the upcoming sessions.
