Transformer rating is done in kva because this rating is
true from either side i.e. either from primary side or
secondary. Also due to cu-losses and self inductance in
primary and secondary, unity power factor is not maintained
and hence it can't be same from either side.

I want the details about BHEL company examination.Can anyone able to help me please.
