The excitation of a three-phase synchronous motor connected in parallel with a load of 500 kW
operating at 0-85 p.f. lagging is adjusted to improve the overall p.f. of the system to 0.95 lagging. If the
mechanical load on the motor is 120 kW, calculate the kVA input to the synchronous motor and its p.f.?
