A 500 KVA, 6600/400 V, 50 Hz single phase transformer .The high voltage and low voltage winding have resistance of 0.422 and 0.0011 2 respectively. The full-load current is obtained when 264V at 50 Hz is applied to (H.V winding) with (L.V winding) short-circuit. Find: i) The equivalent resisance and reactance of the transformer referred to H.V. side ii) The maximum efficiency at 0.8 p.f. lagging, if the efficiency of transformer at 25% full-load is 96.9% when p.f. is 0.8 lagging
