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.
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 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 ....??????
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.
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
