Let the line voltage VL = 208 V and the wattmeter readings of the balanced system balanced system in Fig. 12.35 be P1 = −560 W and P2= 800 W.

Determine:

(a) the total average power

(b) the total reactive power

(c) the power factor

(d) the phase impedance

Is the impedance inductive or capacitive?

Answer:(a) 240 W, (b) 2355.6 VAR, (c) 0.1014, (d)  inductive.
