Three-wye connected load impedances, Z, = 40 + j30 2, 2, = 40 330 2 and 2 20 + 15 2, are connected to an abc-sequence, balanced three-phose, wye-connected source with a line voltage of 400 V. A conductor of impedance j2 Q is used to connect together the neutral points of the source and the load. The line impedance per phase is j4 O. Calculate the load phase Currents and voltages, and the voltage drop in the neutral wire.
