A 400-kVA transformer has a primary winding resistance of 10 and a secondary winding
resistance of 0.002 . The iron loss is 2.5 kW and the primary and secondary windings are
5500 and 200 turns respectively with a secondary voltage of 400 V. If the power factor of the
load is 0.8, determine the efficiency of the transformer (a) on full load, (b) on half load, (c)
the load that provides the maximum efficiency at same power factor, and (d) determine the
maximum efficiency.
