750kva 11/415kv transformer having percentage impedence is5.64%. 11KV HV whose current 39.37A and 415V LV whose current 1043.43A.resistance is 2.5ohm. find no load loss and full load loss?

Answer Posted / k.prakashchandra

LV side ( DC )resistance can not be 2.5 ohm for a current of 1043.43A. Taking usual losses at 0.08 % + 0.08 % , no load loss is 0.6 KW and that at full load 1.2 KW
