Extracted text: Instructions From the following test results, determine the voltage regulation of a 346 kVA, 2,000V, 3 phase Y alternator, at (a) unity pf . (b) 0.8 leading pf (c) 0.71 lagging pf Test results: Full load current at 100A is produced on short circuit by a field excitation of 2,5 A. An emf of 500 V is produced on open-circuit by the same excitation. The armature resistance is 0.8 Q.
