The following data were obtained from tests carried out on a 48 kVA, 4800/240 V, 50 Hz distribution transformer: Open circuit test: 240 V, 7 A, 168 W. Short circuit test: 240 V, 200 A, 240 W. Find Re, Xe, RoXm and label all constants into the appropriate sketch shown below, then sketch the per unit circuit with all constants on its appropriate element. And plot the VR v.s. theta (power factor angle): 0.75% load with 0.8 lagging. W m- eee
