A star-connected 440V, 50Hz alternators has per phase synchronous reactance of 100. It supplies a balanced capacitive load current of 20A, as shown in the per phase equivalent circuit of Fig. It is desirable to have zero voltage regulation. The load power factor should be moo J1022 Eph = 440 V √3 20A Load
