The following figure shows a single-phase power system, consisting of a 50 Hz generator supplying two loads through a transmission line and a pair of transformers at both ends of the line. Assume that both the transformers are ideal and the loads receive a constant voltage of 230 V AC. With switch S1 open, determine the P, Q, and $ of the load ZLoad.
With switch S1 closed, determine the P, Q, and $ of the two loads (combined), the generator's terminal voltage, the P, Q, S, and pf of the generator, and the transmission line losses.
