Q4. The following figure shows a single-phase power system, consisting of 480 V, 50 Hz generatorsupplying two loads through transmission line and a pair of transformers at both ends of

the line. Assume,both the transformers as ideal. a) With switch S1 open, find the real power P, reactive power Q and apparent power S supplied by the generator. Also determine the generator power factor. b) With switch S1 open, determine the P, Q and S of the load ZLoad 1. c) With switch S1 closed, find the real power P, reactive power Q and apparent power S supplied by the generator. Also determine the generator power factor. d) With switch S1 closed, determine the load P, Q and S of both the loads (ZLoad 1 and ZLoad 1)individually and cumulatively. e) What are the transmission line losses with the switch open as well as closed?
