In Figure P16–61 the source and load busses are interconnected by a transmission line with ZW ¼ 10þ

j75 V=phase. The load at bus 2 draws an average power of P2 ¼ 600 kW at a lagging power factor of 0.8 and the line current is IL1 ¼ 14AðrmsÞ. Find the source power factor and the line voltages at bus 1 and bus 2.
