A balanced three-phase Y-connected generator with positive sequence has in impedance of 0.2+ j0.5 0/ph. and an internal voltage of 120 V/ph. The generator feeds a A-connected load through a distribution line having an impedance of 0.3 j0.9 0/ph The load impedance is 118.5+j85.8 02/ph.Use the a-phase internal voltage of the generator as the reference. a) Construct a single-phase equivalent circuit of the three-phase system. b) Calculate the line currents. c) Calculate the phase voltages at the load terminals. d) Calculate the phase currents of the load. e) Calculate the line voltages at the source terminals.
