## Determine maximum neutral current-power factor, Electrical Engineering

Assignment Help:

1.)  A three phase, D0 HP, 1765 rpm, BA0 V induction motor operating at three quarter load has an efficiency of 91% and a power factor of 87%. Determine active power, apparent power, reactive power and line current.

2.) Determine the rated primary and secondary currents and the approximate short circuit currents for a three phase A3,000-B80 V, 250 kVA transformer with a D% impedance. What is the ohmic impedance on the secondary side of the transformer?

3.) A 240 V center-tap transformer serves the following loads:

a. 2 - A500 W at 240V
b. 1 - C200 W at 120 V
c. 1 - D000 W at 240 V
d. 4 - 1500 W at 120
What are the two line currents and neutral current when balanced as closely as possible? What is the maximum neutral current?

4.) A three phase 480 V source supplies a B00 kW load and B00 kVAR capacitor at unity power factor. What is the power factor of the load without the capacitor?
