1. A 1000-VA 350/140-V transformer has been tested to determine its equivalent circuit. The results of the tests are shown below. Open-circuit test Short-circuit test Voc = 235 V Vsc = 20.1 V loc = 0.57 A Isc = 9.6 A Poc = 34.3 W Psc = 42.7 W All data given were taken from the primary side of the transformer. Evaluate the equivalent circuit of this transformer referred to the low-voltage side of the transformer.
