Techniques for On-Line Diagnosis of Stator Shorted Turns in Induction Motors

In low voltage induction motors, the first indication of a stator fault is the appearance of an inter-turn short circuit. For this reason, several attempts to diagnose reliably these short circuits have been made. Although considerable research has been carried out, the diagnosis of inter-turn short...

Sumario:In low voltage induction motors, the first indication of a stator fault is the appearance of an inter-turn short circuit. For this reason, several attempts to diagnose reliably these short circuits have been made. Although considerable research has been carried out, the diagnosis of inter-turn short circuits is not a mature technique yet. This paper presents and analyzes the on-line inter-turn short circuit diagnostic techniques developed so far for line-connected induction motors. By means of a comparative study, their advantages and drawbacks are highlighted.
