From the following test results, determine the voltage regulation of a 2000-V 1-phase alternator delivering a current of 100 A at (i) unity p.f. (ii) 0.8 leading p.f. and (iii) 0.71 lagging p.f. Test results: Full-load current of 100 A is produced on short-circuit by a field excitation of 2.5A. An e.m.f. of 500 V is produced on open-circuit by the same excitation. The armature resistance is 0.852 From the following test results, determine the voltage regulation of a 2000-V 1-phase alternator delivering a current of 100 A at (i) unity p.f.
