A 3Ø, 1000KW, 2500V alternator is open-circuited and is operated at rated speed to produce rated current at 4A excitation. Maintaining the open-circuit and with the excitation adjusted to 4A, the voltage between stator terminal is 1300V. The effective resistance between terminal as measured with dc is 2Ω. Determine the %V.R. of the alternator at half-load and pf of 0.8 lagging. Note: Please read and analyze carefully the problem question.

Question

A 3Ø, 1000KW, 2500V alternator is open-circuited and is operated at rated speed to
produce rated current at 4A excitation. Maintaining the open-circuit and with the
excitation adjusted to 4A, the voltage between stator terminal is 1300V. The effective
resistance between terminal as measured with dc is 2Ω. Determine the %V.R. of the
alternator at half-load and pf of 0.8 lagging.
Note: Please read and analyze carefully the problem question.
