Determine the total power in balanced delta-connected load, Electrical Engineering

Assignment Help:

Q. Two wattmeters are used, as shown in Figure, to measure the power absorbed by a balanced delta-connected load. Determine the total power in kW, the power factor, and the per-phase impedance of the load if the supply-system voltage is 120 V and the wattmeter readings are given by

(a) W_A =-500 W, and WC = 1300 W.

(b) W = 1300 W, and W =-500 W.
