Determine the efficiency of the transformer, Physics

Assignment Help:

A 400kVA transformer has a primary winding resistance of 0.5Ω and a secondary winding resistance of 0.001Ω .

The iron loss is 2.5kW and the primary and secondary voltages are 5kV and 320V respectively. If the power factor of the load is 0.85,
