    DISCRETE WAVELET ANALYSIS FOR STATOR FAULTS DETECTION IN INDUCTION MACHINE
    (university of eloued جامعة الوادي, 2020-01-01) R., Kechida1,; , . Menacer 2 A.
    The induction motors are not always operating under complete steady state conditions, therefore prompting the development of non-stationary techniques for fault detection. In this paper an inter-turn short circuit fault is considered in the stator winding. The technique for diagnosis in transient state, especially in startup state is based from using the DWT. The signal used for the fault detection is the stator current. The experimental results show that using DWT can effectively be used to diagnose this type of the fault in the motor.
