11 kV at a power factor of 0.867lagging. Each machine supplies half the total power. The synchronous reactance of each is 500 perphase and the resistance is 40 per phase. The field excitation of the first machine is so adjusted that its armature current is 35 A lagging. Determine the amature current of the second alternator and the generated voltage of the fir machine.

Three identical 3-phase altemators work in parallel and supply a total load of 1493.3kW at 11 kV at a power factor of 0.867 lagging. Each machine supplies halfthe total power. The synchronous reactance of each is 50 0 perphase and the resistance is 40 per phase. The field excitation of the first machine is so adjusted that its amature current is 35 A lagging. Determine the armature current of the second altemator and the generated voltage of the first machine.
