摘要
This paper presents a strategy for detecting stator inter-turn faults in induction motors (IM), by using a zero sequence high-frequency signal injection. The derivatives of the motor currents are analyzed. The subsequent signal processing allows us to study how these signals change its value as a consequence of stator inter-turn faults. A feature of the strategy is that the zero sequence high-frequency signal is generated by a standard space vector modulation of the IM drive. Experimental results are presented, validating the fault detection strategy.
