Two three phase generators supply a three phase load through separate three phase lines. The load absorbs 30 kW at 0.8 power factor lagging. The line impedance is (1.4 + j 1.6) ohms per phase between generator G1 and the load, and (0.8 + j1.0) ohms per phase between generator G2 and the load. If generator G1 supplies 15 kW at 0.8 power factor lagging, with a terminal voltage of 460 V line to line, determine the voltage at the load terminal.
