A 1500KVA, 8KV, three-phase wye-connected alternator has an effective resistance of 0.502 and a reactance of 62 per phase. It delivers full-load current at 0.8 lagging power factor at rated voltage. What will be the terminal voltage for the same excitation and load current, if the power factor is 0.8 leading?
