An abc-phase-sequence three-phase balanced wye-connected 60-Hz source supplies a balanced delta-connected load. The phase impedance in the load consists of a 20-Ω resistor series with a 20-mH inductor, and the phase voltage at the source is V_an = 120 < 30^o V rms. If the line impedance is zero, find the currents in the system.
