IEEJ Transactions on Industry Applications, 1993 The induction of zero-phase-sequence voltage by negative-phase-sequence current in a salient pole synchronous generator is proved experimentally and theoretically. In the method of symmetrical coordinates, it has been believed that positive-, negative- and zero-phase-sequence components are independent. But an experiment driving a synchronous generator
