A 4 kVA, 50 Hz, single-phase transformer has a ratio 200/400V. the data taken on the l.v. side at the rated voltage show that the open circuit input wattage is 80W. The mutual inductance between the primary and the secondary windings is 1.91H. What value will be the current taken by the transformer, if the no-load test is conducted on the h.v. side at rated voltage? Neglect the effect of winding resistance and leakage reactances.
