The balance three-phase source in Figure P16–54 produces an average power of 15 kW at a power factor of 0.85 lagging. The line impedance is ZW ¼ 3 þ j15 V=phase and the balanced load has a phase impedance of ZD ¼ 250 þ j55 V=phase. Find the line voltage VL at the load and complex power delivered to the load.
