I need the answer as soon as possible
Four identical 3-phase altemators workin 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 2 perphase and the resistance is 42 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 altemator and the generated voltage of the first
machine.
