Determine the operating power factor of a 6.6kV Y-connected synchronous motor has a synchronous reactance per phase of 10 ohms and a negligible resistance. For a certain load, the motor draws 990,000 watts at normal voltage. At this load, the induced emf per phase is 5.16kV. 0.502 O 0.478 0.462 0.518
