Sir please start a playlist of detail fault analysis of generator protection relay.... and it's calculation..each and every settings of generator protection relay.... It will be very informative.... otherwise your all videos are too valuable...and I got proper idea on your videos... So please make videos on this .... Thank you...🙏🙏🙏🙏
Dear engineer, can you help me? I have had a rotor to ground fault in a 56MVA generator, 12 salient pole rotor, vertical axis, the protection relay did not detect the fault and I pressed the emergency stop, however the stator was damaged due to unbalance. I would like to know if there is an electrical circuit to test and verify that the relay is operating correctly, I would appreciate your kind response. regards
You need to simulate rotor earth fault condition by decade resistance box, change resistance from high to trip value and note down the trip threshold resistance value.
Pl explain method to check rotor earth fault. How we we may check that whether relay is faulty or there is actual fault. As i am facing problem with siprotec 7um62. When we start generator it trips after sometime on rotor earth fault and after 2 or 3 trippings the system becomes normal. Is there any chance that dust or moisture is causing this???

Sir please keep posting videos, good to see you back.
Sir... You explain it in very simple way.. Thanks
Very nice lecture. ❤❤
Excellent lecture Sir. Thanks 🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏
Thank you sir for explaining us so clear way..sir please post video on stator earthfault 95 and 100%

Sir u r back , kindly continue to post videos , ur way of explanation is wonderful , m ur big fan 🙏🙏
Thank you very much sir 🙏
Sir,Thanks for the nice video...if possible do a video similarly on 100% stator earth fault detection through injection principle
Ooh electro ocean where have you gone? we need you
Excellent
Excelente explicação.
good one
As you share related to generator, i request you to also share testing of generator.
Thank u sir pls keep posting.
Sir abhi aapka koi chanel active hai kya
Can you please upload video for SFC & SEE OPERATING PRINICOPLE OF GENERATOR WITH HELP OF GCB.
This is good subject
Thanks!
Sir,why series resistances are kept in the circuit?
Sir, why square wave is taken for injection

Sir please make video on diffrent class of protection like A,B,C,D and action when class A,BC,D, protection acted which bkr trip..in diffrent class..
Sir please make a video on class a class b and class c protection and the tripping values we give in relay.
RE and C is represent to insulator sir ?
pls help answer sir

u may test the calibration of rot ef measurements by using a resistance box between excitation dc ckt and ground
It may have dynamic earth fault...
May be some foreign material is causing it at 3000rpm..
Sir if rotor earth fault occurred, how to rectify it

MX3IPG2A RELAY EXPLAIN SIR
Please explain in hindi
Hindi please sir
Hindi
i am watching the video 3-4 times pr ghanta mujh kuch samjh aaya
Sir please Hindi me samjhiye na
Hindi plz
