Transcribed Image Text:

Assume that a three-phase 500 hp 60 Hz 4160 V Wye- connected induction motor has a full load efficiency (n) of 88% and a lagging power factor of 0.75 and is connected to a feeder. If it is desired to correct the power factor of the load to a lagging power factor of 0.9 by connecting three capacitors at the load, determine the following: A. the rating of the capacitor bank in kvar. B. the capacitance of each unit if the capacitors are connected in delta, in μF. C. the capacitance of each unit if the capacitors are connected in wye in μF.
