A 3Ø, Y-connected alternator is rated at 1,600KVA, 13.5KV. The
armature effective AC resistance per phase is 1.5Ω. The percentage
regulation for a load of 1,280kW at unity power factor is 3.5%.
Determine: (a) synchronous reactance of the alternator (b) %VR at
full-load 0.8pf leading (c) What is the effect on %VR value if
taken at half-load lagging pf? Justify and explain briefly your
answer on one(1) sentence.
