A 90-MVA 69.3-kV, three-phase synchronous generator has a synchronous reactance of 10 Ohms/phase and negligible armature resistance. The generator is delivering power to the bus bar at the rated voltage with its field current adjusted for a generated emf (excitation voltage) of 50 kV per phase and a power angle & = 7.1 degree. Thus, the delivered power is the generator armature current is and the power factor is
