Fault Diagnosis Of VSI-FED Three-Phase Induction Motor
This paper aims at developing an efficient tool for the fault diagnosis of VSI-fed 3-phase Induction motor. The
considered faults include stator winding faults of the induction motor and open power switch faults in the voltage source
inverter. Any single phasing situation creates the stator fault that may result in opening of one or more phase windings. In this
work, the induction motor model is modified for analyzing the open circuit fault of the stator phase winding and the current
patterns obtained using Park’s Vector Approach are compared. The power switch faults in the converter are analyzed using
Normalized Currents Average Values method.
