(a) A 60-kVA, 4800/2400-V single-phase transformer gave the following test results: Rated voltage is applied to the low voltage winding and the high voltage winding is open-circuited. Under this condition, the current flow into the low voltage winding is 2.4 A and the power taken from the 2400 V source is 3456 W. A reduced voltage of 1250 V was applied to the high voltage winding and the low voltage winding was short- circuited. Under this condition, the current flowing into the high voltage winding is 12.5 A and the power which is taken from the 1250 V source is 4375 W. Design the equivalent circuit referred to the high voltage side by considering: Open circuit test (ii) Shunt parameters referred to high voltage side (iii) Short circuit test
