EE 320 - Electric Circuits 2

Midterm Quiz 3

1) Abalancedthree-phaseY-sourcewithVP210Vrms drives a Y-connected three-phase load with phase impedanceZA 80,ZB 60j90,and

ZC j80 . Calculate the line currents and total complex power delivered to the load. Assume that the neutrals are connected.

2) The source in Fig. 12.65 is balanced and exhibits a positive phase sequence. If f 60 Hz, use PSpice to find VAN, VBN, and VCN.

3) Two wattmeters are properly connected to the unbalanced load supplied by a balanced source such that Vab = 208 |_0 V with positive phase sequence.

(a) Determine the reading of each wattmeter.

(b) Calculate the total apparent power absorbed by the load.

4) three-phase delta-connected motor load which is connected to a line voltage of 440 V and draws 4 kVA at a power factor of 72 percent lagging. In addition, a single 1.8 kVAR capacitor is connected between lines a and b, while a 800-W lighting load is connected between line c and neutral. Assuming the abc sequence and taking Van = Vp |_0 V, find the magnitude and phase angle of currents Ia, Ib, Ic, and In.
