In low voltage induction motors, the first indication of a stator fault is the appearance of an interturn 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 interturn short circuits is not a mature technique yet. This article presents and analyzes the online interturn short circuit diagnostic techniques developed so far for line-connected induction motors. By means of a comparative study, their advantages and drawbacks are highlighted.
