A balanced, positive-sequence, Y-connected voltage source with Eab = 480/0° volts is applied to a balanced-A load with ZA = 30/40° 2. The line impedance between the source and load is ZL = 1/85° 2 for each phase. Calculate the line currents, the A-load currents, and the voltages at the load terminals.
