A 3Ø, 2000KW, 480V A-connected alternator is short-circuited and is operated at rated speed to produce rated current at 4A excitation. With the short-circuit remove and with the excitation adjusted to 5A, the voltage between stator terminal is 330V. The effective resistance between terminal as measured with dc is 20. Determine the %V.R. of the alternator at half-load and pf of 0.8 leading without changing any given values.
