Abstract

PURPOSE:To improve performance by discriminating a defective state by comparing the ratio of the AC output voltage to the excitation current of an AC exciter with the predetermined set value, thereby continuing the operation as long as possible. CONSTITUTION:A divider 14 calculates the ratio alphaX of an output voltage V0 to the exciting current I1. Comparators 14A-14D compare the ratio alphaX calculated by the divider 14 with the set values alphaX1, alphaX2, alphaX3, alphaX4 determined in response to the defect mode to discriminate which mode is defective, and output to light emitting diodes 17A-17D and relays 18A-18D. Thus, the operation is stopped when the specific mode is defecive. Thus, the operation is continued as long as possible.
