Answer Posted / k.prakashchandra
Earth fault relay is not connected any phase.The balancing
current is made to pass through this relay.In two EFR and
one EFR protection scheme,OCR s are usually provided on R
and B phases ,which makes one assume that the EFR is
provided on Y phase.You can have 3 OCR and 1 EFR protection
scheme also
