Three zones of a single-phase circuit are identified in Figure (a) below. The zones are connected by transformers T1 and T2, whose ratings are also shown. Using base values of 40 kVA and 500 volts in zone 2, draw the per-unit circuit and determine the per-unit impedances and the per-unit source voltage. Then calculate the load current both in per-unit and in amperes. Transformer winding resistances and shunt admittance branches are neglected.
