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.
Dear sir, I have got a lot of knowledge from your videos. Thanks aot However,can you explain us in details the full schematic drawing of HV circuit breaker. THANKS A LOT FOR YOUR GENUINE SOLIDARITY
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.
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 ....??????

Very good explanation of pumping but I would only ask that you talked about how the antipumping stops the pumping.

your all videos are very helpful.

Sir.. well explained 👍🏻.. Ur presentation is so simple.. Very effective
Glad you enjoyed it!!
Sir all videos are very helpful and ur explanation is awesome.... sir please make video on Banavathy make battery charger
Finally I understand in this video.. thank you sir
Excellent explanation
What is the difference of Phase-to-phase, phase-to-
earth, open contact gap and
Across isolating distance, Please explain details thank you.
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
Sir please explain busbar protection
Sir in vaccum circuit breaker how to check vaccum cylinder before safe operation.
Tnx .very well
Glad it was helpful!
great, thank you!
Glad it was helpful!
Pls share Control schematic drawing
Helpful
Glad you think so!
Good
Thank you 😊
Great
Yes
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
110 V or 220 DC? or AC?
Mostly commonly DC is used.
sIR CAN YOU EXPLAIN WHAT IS DIFFERENCE BETWEEEN EARTHING AND BOLTING ? JAI HIND ...!
How can someone enrol in the online course and the cost
hello. you can check all the details at courses.theelectricalguy.in
@@GauravJ Idont Have that much amount, How can you help please?
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.

I thought anti pumping circuit will also be explained.
The pic is not mine, rather of my grandson.
Course
cant understand too much unecessary info
