Accurate diagnosis of slight inter-turn short circuit fault (ISCF) of permanent magnet synchronous motor (PMSM) has always been a difficult problem in the field of electrical engineering. Aiming at the problem of ineffective ISCF diagnosis, a method on Phase angle diagnosis of zero-sequence components is proposed.

Zero-sequence components in unit-connected generator with ungrounded neutral during ground-faults
PowerCon 2000. 2000 International Conference on Power System Technology. Proceedings (Cat. No.00EX409), 2002An analysis of voltage zero-sequence components in a generator during normal operation (pre-fault conditions) and during ground-faults in stator winding of generator with ungrounded neutral is presented. The changes in voltage zero-sequence components of fundamental frequency and 3rd harmonic during generator pre-fault conditions, ground-faults in ...

Transformers neutral grounding accessing small reactance is an effective measure to restrain short circuit current in 500kV power grid. But accessing small reactance will bring changes to the zero-sequence parameters of system. The relay protection, especially the main transformer protection and transmission line protection nearby will be affected and ...
