In a balanced three-phase system, the source is a balanced wye with an abc -phase sequence and V ab = 208 60° V rms. The load consists of a balanced wye with a phase impedance of 8 + j 5 in parallel with a balanced delta with a phase impedance of 21 + j 12 . If the line impedance is 1.2 + j 1 , find the phase currents in the balanced wye load.
