Signal processing tools for monitoring induction drive

This paper consists of three parts. In the first, the faults under study are listed. The simulation models used to characterize the faults occurring in the electrical drive and to validate the fault detection and isolation methods are presented. In the second part, a spectral characterization is performed for each considered fault on the observable signals appropriate for each component of the drive (voltage, current or speed). Signal based detection methods are presented in the third part and are validated in simulation
