The output of a station with two alternators in parallel is 30,000 kW at a lagging power factor (pf) of 0.707. One of the machines is loaded to 15,000 kW at a pf of 0.80 lagging. Calculate the MVA loading and pf of the other machine.
A 3-phase, 16-pole alternator has a wye-connected armature winding with 144 slots, 10 conductors per slot, and runs at 450 rpm. The flux per pole is 40 mWb, and the distribution factor is 0.966. What is the value of the line-to-line voltage?
A 3-phase, 4-pole alternator has a single-layer full-pitch winding with 8 conductors per slot. The armature has a total of 36 slots. Determine the voltage between lines when the alternator is driven at 1800 rpm with a flux of 0.05 Wb per pole.
