For a 4 KVA, 200/400 V, 50 Hz, 1 - phase transformer, calculate the efficiency, voltage at the secondary terminals and primary input current when supplying a full - load secondary current at 0.8 lagging power factor. The following are the test results: Open circuit with 200 V applied to the L.V. side: 0.8 A, 70 W. Short circuit with 20 V applied to the H.V. side: 10 A, 60 W.
