Assume that a three-phase 500 hp 60 Hz 4160 V wye-connected induction motor has a full-<br>load efficiency (n) of 88% and a lagging power factor of 0.75 and is conne cted to a feeder. If it is<br>desired to correct the power factor of the load to a lagging power factor of 0.9 by connecting three<br>capacitors at the load, determine the following:<br>a. The rating of the capacitor bank, in kilovars<br>b. The capacitance of each unit if the capacitors are connected in delta, in microfarads<br>c. The capacitance of each unit if the capacitors are connected in wye, in microfarads<br>
