Stator Line Faults Diagnosis of Induction Motor Drive Using Park's Vector Approach

Monitoring and fault diagnosis in induction motor has been a challenging task for the engineers in recent industrial applications. In general, current monitoring techniques are usually applied to detect various types of induction motor faults. The present work proceeds with the fault diagnosis in voltage source inverter fed induction motor using current parks vector approach. In this paper, different types of faults such as 3-∅ short circuit fault, L-L faults and open circuit faults are introduced and diagnosed using the current park spectrum where the spectrum differs from the ideal to the faulty condition.
