The following test data were obtained from short-circuit and open circuit tests of a 5-kVA, 2400-600V, 60Hz transformer. Voc=600V Ioc=3.34A Poc=484W
Vsc=76.4V Isc=20.8A Psc=754W
Determine (a) the equivalent high-side parameters; (b)regulation; (c)efficiency at rated load and 0.92 power factor lagging.
