A balanced three-phase Y-connected source with positive sequance has an internal voltage of 120 V/phase. The source feeds a balanced three-phase Y-connected load having an impedance of 39 + j28 N /phase. The impedance of the transmission line connecting the source to the load is 1+ j20/phase. The a- phase of the source is the reference voltage. a) Draw the equivalent per-phase-circuit for the phase "a". b) Calculate the three line currents in the transmission lines. c) Calculate the three phase voltages at load. d) Calculate the three line-to-line voltages at the terminals of the load.
