In Figure P16–61 the source and load busses are interconnected by a transmission line with ZW ¼ 2þ

j10 V=phase. The load at bus 2 draws an average power of P2 ¼ 50 kW at a lagging power factor of 0.8 and the line voltage at bus 2 is VL2 ¼ 4:16 kVðrmsÞ. Find the apparent power produced by the source at bus 1, the source power factor, and the line voltage at bus 1.
