A straight-line law connects terminal voltage and load of a 3-phase star connected alternator delivering current at 0.8 power factor lagging. At no-load, the terminal voltage is 3,500 V and at full-load of 2,280 kW, it is 3,300 V. Calculate the terminal voltage when delivering current to a 3-phase, star-connected load having a resistance of 8 o and a reactance of 6 ohm per phase. Assume constant speed and field excitation.
