A 3- phase, 4 – wire, 380 V supply is connected to an unbalanced load having phase impedances of ZR = (8 + j6) Q, ZY = (8 - j6) Q and ZB = 5 Q. Impedance ofthe neutral wire is ZN = (0.5 +j1) Q. Ignoring the impedances of line wires and intemal %3D impedances of the emfsources, find the phase currents and voltages of the load.
