Abstract :
An accurate model and reliable detection system of an induction motor is a very important tool for diagnostic and fault detection. This paper deals with modelling of an inter-turn short circuit in stator and rotor windings of an induction machine and the fault detection at start-up. Winding function approach is chosen for the fault modeling and time-frequency analysis is proposed for the detection of fault. The detection method is based on detection of sidebands at certain frequencies using Wigner-Ville Distribution.
