A 600 kVA transformer has a primary winding resistance of 0.60 and a secondary winding resistance of 0.002 Q. The iron loss is 2.6 kW and the primary and secondary voltages are 6 kV and 330 V respectively. If the power factor of the load is 0.8, determine the efficiency of the transformer (i) on full load, and (ii) on half load.
