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 +J1.6) Ω per phase between generator G1 and the load, and (0.8 +jl ) Ω per phase between generator G2 and the load. If generator Gl supplies 15 kW at 0.8 power factor lagging, with a terminal voltage of 460 V line- to-line, determine 1. The voltage at the load terminals. 2. The voltage...
