(b) A 40-KVA, 2600/1300-V, single-phase transformer has a core loss of 620 W. The transformer has a high voltage winding resistance of 0.15 N and a low voltage winding resistance of 0.0125 12. Neglect the effect of primary and secondary inductances and calculate the transformer efficiency at the rated load and unity power factor.
