A three-phase wye-connected load is supplied by an abc -sequence balanced three-phase wye-connected source through a transmission line with an impedance of 1 + j 1 per phase. The load impedance is 8 + j 3 per phase. If the load voltage for the a phase is 104.02 26.6° V rms (i.e., V p = 104.02 V rms at the load end), determine the phase voltages of the source.
