A 800-kVA, 2300-V, three-phase, Y-connected, synchronous generator is operated at its rated speed to obtain its rated no-load voltage. Later, another test finds that the short-circuit phase current is 129 A. The average resistance of each phase is 0.6 ohm. 1) Determine the synchronous reactance per phase. 2) Determine the voltage regulation when the generator delivers the rated load at its rated voltage and 0.78 PF lagging.
