A single-phase, 200-V/2000-V transformer is fed from a 200-V supply. The equivalent winding resistance and leakage reactance as referred to the low voltage side are 0.16 Q and 0.7 0, respectively. The resistance representing core losses is 400 n and the magnetizing reactance is 231 0. A load impedance of ZL (596 + j444) Q is connected across the secondary terminals. Calculate (a) the input current, (b) the secondary terminal voltage, (c) the primary power factor. A single-phase, 200-V/2000-V transformer is fed from a 200-V supply.
