I read this topic from different books yet I was not able understand the drawback of simple differential delay.After watching your video I understood easily. Thanks Sir😊

[@aniketgangwar3867]

Sir why we use balancing resistance instead we have baised differential protection scheme

[@jyothishkv]

Sir what happens if we don't ground neutral as well as generator body?

[@lollotshangela6154]

Thanks once again for referring me back to here. but however I GET THE CONCEPT BUT NOW THE QUESTION STILL IS:
how would we go about calculating setting of the ct ratio for turbo generator(with 800MVA, 15kV) connected to a step transformer and a unit transformer which supplies the aux?
THANK YOU SIR

@@lecturesinelectricaleng thank you appreciated for your informative and way forward!! Sir please continue the good work ! South Africa

[@chandudhakar3951]

Sir why stabilizing register is connected??

[@sumitkumarDTU]

Sir why the stator windings are mostly connected in star? By the way your lectures are very helpful. Thanks for making them.

[@rjshtk]

In star winding, the phase to earth insulation is only 1/rt3 times the line voltage. Hence cost of insulation can be minimized. In Delta, all points of the windings have to be insulated for Full Line voltage value. Insulating cost invilved will be more in this case..

Sir please provide its notes.
