That's a great problem statement explanation. Really a great educator. Hope to see a lecture on DC system. As it is an important topic for interviewers. Cheers! Have a good!
Sir can we get some videos on protection scheme used in power system like 87G generator differential, bus bar differential, over voltage, over current etc.
Very good explanation of pumping but I would only ask that you talked about how the antipumping stops the pumping.
Sir.. well explained 👍🏻.. Ur presentation is so simple.. Very effective
Glad you enjoyed it!!
Thank you 😊
Sir all videos are very helpful and ur explanation is awesome.... sir please make video on Banavathy make battery charger
great, thank you!
Glad it was helpful!
Helpful
Glad you think so!
Good
Sir please explain busbar protection
Tnx .very well
Glad it was helpful!
Great
Sir i want to relay testing , co-ordination and time calculation any videos is there please suggest me
This is course, I like it,on line?
Yes it available on
courses.theelectricalguy.in
You explained what Pumping is but never explained how it is prevented. Why? How does an Anti Pumping circuit look like?. I was curious to see it.
Check out courses.theelectricalguy.in for that

@@GauravJ Idont Have that much amount, How can you help please?
Sir
I am not completely agree with your explanation. When there's a fault ,Relay detect then Master Trip relay give command to Trip coil to Trip.Till we are not reset the relay ,how again breaker close ....??????
Sir
The breaker will not close until the master trip is not resetted.
Master trip or lockout relay feature to inhibit reclosing on SOTF is an extra arrangement or benefit. The foremost requirement is: first the CB must have anti-pumping feature. Sometimes, discharged closing spring also can benefit against the inadvertent reclosing, a matter of 5 to 20 seconds.
110 V or 220 DC? or AC?
Mostly commonly DC is used.
