480 V, 50 Hz, 6 pole, star connected generator has phase reactance 1.2 Ω and phase active resistance Is 0.8 Ω. The full load current of the generator is 60 A at 0.8 back power factor. Friction and wind losses are 1.5 kW, core losses are 1 kW. With 5 ampere excitation current when the generator is unloaded the terminal voltage is 480 V. Excitation circuit voltage is 200 V. According to this; a-) total power to be given to the generator, b-) terminal voltage of the generator under load
