TLDR
There are several methods for detecting shorted turns in the stators of induction motors and some of them are simple, straightforward and efficient.Abstract:
Stator-related failures in induction machines are often encountered in industrial applications due to the unforeseen insulation damage This paper addresses the fast prognosis of inter-turn faults It presents simulation and measurement of the stator winding short circuit faults of a three-phase induction motor A 50 Hz four-pole 2 hp induction motor was operated under healthy and faulty conditions and the increase in backward sequence current component assessed It was found that the negative sequence component is a powerful component for the detection of inter-turn faults and simple algorithms allow it to be monitored and faults detectedread more
