(6)A 3.3-KV 3-phase star-connected synchronous motor, whose synchronous reactance is 12 2/phase and whose resistance is negligible, takes 100 kW input power at 0.6 p.f. leading. If the load on the motor is increased, without any change in excitation, until the input power factor is unity, determine the input power. (519 kW)
