  1. A wye-connected 200 kVA, 440 V, 3-phase alternator yields 150 V between the terminals on short circuit. With the field excitation unchanged, the short circuit current is 300 A. The ohmic resistance of this machine between line terminals is 0.10 ohm and the ratio of the effective to ohmic resistance is 1.25. Calculate the full load terminal voltage of the machine when the excitation is adjusted to yield a no-load of 500 volts between lines and the power factor is 0.80 lagging.
