Considering Figure, let balanced positive-sequence, three-phase voltages with ¯VAB = 100√3 0° V (rms) be applied to terminals A, B, and C. The three-phase wye-connected balanced load consists of a per-phase impedance of (10 + j10). Determine the wattmeter readings of WA and WC. Then find the total three-phase real and reactive powers delivered to the load. Based on the wattmeter readings of WA and WC, compute the load power factor and check the sign associated with the power factor angle.
