A 1000 KVA, 3000 v, 50 Hz, three-phase delta-connected alternator has an effective armature resistance of 0.2 Ω. A field current of 40 A produces a short- circuit current of 200 A, and an open-circuit voltage of 1040 V (line-to-line). Calculate the full load percentage voltage regulation at a power factor of 0.8 lagging. How will the regulation be affected if the alternator delivers its full load output at a power factor of 0.8 leading?
