Question

A single-phase transformer, with primary turns of 500, is delivering full-load of 80 kW at
a lagging power factor of 0.8 from a 220 V, 50 Hz supply. The current delivered to the
load is 227 A.
iv. Determine the current drawn from the supply.
v. Assume the core and copper losses are 800 W and 3200 W respectively. Detemine the
input power and efficiency of the transformer.
vi. If the load impedance on the transformer is doubled, what will be effect on the core
and copper losses? What is the efficiency at this operating condition?
