A 1500 hp phase ac motor load has a power factor of 0.7. What capacitor (in Farads) is required to correct the power factor to 0.90 if the line voltage is 2400 volts? The capacitor bank is to be delta connected.
This is more less an arithmetic problem. Here are the steps. 1. Determine R and L of the motor. You know power, voltage and PF. 2. Determine the desired load (Zload) in order to get an overall PF of .9. 3. Determine the required capacitance from you knowledge of Zload.
