a . Consider a single-phase transformer with a capacity of 50 kVA, and turn ratio of 20: 1. The system frequency is 60 Hz . A load, which is connected to the secondary winding of the transformer, absorbs the total 40 kV A power at 0.8 pf (lagging) and operates at 220 V (RMS). Assuming the transformer is an ideal one, find the following: a) Primary supply voltage. b) Load impedance. c) Load impedance referred to the primary. d) The real and reactive power supplied to the primary winding. 20:1 220V Load 40 kVA P.F.= 0.8 Primary Secondary
