The equivalent circuit impedances of a 20 kVA, 800/240 V, 60 Hz transformer are to be determined, the open circuit test and the short circuit test were performed on the primary side of the transformer, and the following data were taken: Open circuit test (primary) Short circuit test Voc = 8000 V Vsc = 489 V loc = 0.214 A Isc = 2.5 A Poc = 400 W Psc = 240 W Find the impedance of the approximate circuit referred to the primary side and sketch the circuit.
