A three-phase line has an impedance of 1 +j3 ? per phase. The line feeds a balanced delta-connected load, which absorbs a total complex power of 12 + j5 kVA. If the line voltage at the load end has a magnitude of 240 V, calculate the magnitude of the line voltage at the source end and the source power factor.
