PROBLEM:
• A 3-phase, 4-wire, 380V supply is connected to an unbalanced load having phase impedances of ZR=(8+j6)Ω, Zr=(8-j6)Ω and ZB=5 Ω. Impedance of the neutral wire is ZN=(0.5+j1)Ω. Ignoring the impedances ofline wires and internal impedances of the emf sources, find the phase currents and voltages of the load.
