In this paper, Discrete Wavelet Transform is used to detect the inter-turn fault in the stator winding of aninduction motor and a detailed interpretation of the signals resulting from DWT is provided for each case underhealthy as well as stator inter-turn faulty operating condition, using wavelet technique has been proposed. The testswere carried out in the laboratory using a three phase squirrel cage induction motor having four poles, 550 turns perphase winding on the stator, and rated 1.5 kW, 415 V, 50 Hz. The phase currents were used as the diagnostic signalusing filtering techniques have been also proposed. The results obtained for both healthy and faulty condition for theproper diagnosis of the faulty condition
