Abstract
Induction motors are affected by many electrical faults that are caused by work stress. These faults need to be detected and treated during the first moments of its occurrence to avoid damage of these motors. In this work, an algorithm that based on wavelet packet transforms (WPT) and wavelet energy approach (WE) is proposed. The algorithm is developed depending on moving frame strategy to check the current motor signal with each digital sample. This algorithm is applied on two induction motors, the first represents modeling of induction motor in Matlab2019a while the second is an implementation of real 3-Ph induction motor. The results show accurate detection and diagnosis of the faults with high speed in isolating the power supply from the motor.
