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.?
A domestic load of 2300 kW at 0.88 p.f lagging and a motors load of 3400 kW at 0.85 p.f lagging are
supplied by two alternators operating in parallel. If one alternator is delivering a load of 3300 kW at 0.9 p.f
lagging, what will be the output power and p.f of the other alternator?
