Why can't we take NO LOAD TRIAL of motors having V1 mounting??
if negative of DC supply used and positive is grounded through EGB, and if ELCB used in the system then is it sense the positive volatge and get tripped is it possible?
current transformer balance the power level on both sides. e.g in case of step up, at secondary side voltage rise but current decrease and vice versa in case of step down transformer. but how this power level remains same in case of current transformer and voltage transformer
why does the magnetic balance tests at transformer?

I am using submission of two ct in one and half scheme for 67/67N protection. Both CTs star point is grounded separately near ct box.Will two point ground give wrong tripping to 67/67N during fault or no matter.
At light load transformer efficiency is less because A secondary output is low B transformer losses are high C fixed loss is high compared to output D copper loss is small
