In a balanced 3 phase system, the source is a balanced wye with an abc-phase sequence and Vab = 208<60° Vrms. The load consists of a balanced wye with a phase impedance of 8+j5Ω in parallel with a balanced delta with a phase impedance of 21+j12Ω. If the line impedance is 1.2+j1Ω, find the phase currents in the balanced wye load.
