A 762 KVA. 2200V. 50Hz.three-phase.star- connected alternator has an effective resisance of 0.6 ohm per phase. A field current of 30A produces a full-load current on short circuit and a line to line emf of 1039V on open circuit. Detrmine the power angle of the alternator when it delivers full load at 0.8p.f lagging. Also determine SCR of the alternator
