Abstract

The paper focuses on experimental investigation for stator faults detection and fault detection methods of electrical drive systems using voltage source inverter (VSI) fed cage rotor induction machines (CRIM). Two experimental investigations (one stator phase unbalance and one stator phase open) have been performed to study the behaviour of the electrical machine. A description of the measurement system including acquisition and processing of the data is presented and stator current signature, current Park´s vector and instantaneous power as diagnostic techniques are considered.
