20. Repeat the solution of Prob. 19 21. A three-phase 1,000-kva 2,300-volt alternator is short-circuited and is operated at rated speed to produce rated current. With the short circuit removed and the same excitation, the voltage between stator terminals is 1,300. The effective (corrected) resistance between stator terminals is 2 ohms. Determine the per cent regulation of the alternator at a power factor of 0.8 lagging. 22. Repeat Prob. 21 for a power factor of 0.8 leading. 23. A 1,000-kva 4,600-volt three-phase alternator is short-circuited, and, operating
