A three-phase star-connected alternator working at 1400 KVA,50 Hz,2300 V, has an armature dc resistance of 0.15 N. Assume the ac resistance is 13 times the dc resistance. A field current of 65 A produces a short circuit current of 380 A and for the same field current the open circuit voltage is 800 V. Determine a) Synchronous reactance of the machine b) Full load regulation at 0.9 lagging <) Power angle a)
