3.15 An industrial plant consists of several induction motors. The plant absorbs 300 kW at 0.6 PF lagging from the substation bus. a. Compute the required kVAR rating of the capacitor connected across the load to raise the power factor to 0.9 lagging. b. A 200-hp, 90% efficiency, synchronous motor is operated from the same bus at rated conditions and 0.8 power factor leading. Calculate the resulting power factor.
