Abstract
In this work induction motor faults detection using electrical signature analysis techniques are introduced, and the advantages and disadvantages of these techniques are explained. Stator phase current signature, stator current locus diagram, stator current vector signature, partial power signature, and total power signature are selected for the simulation study applied for 4Kw squirrel cage induction motor. Simulation results are shown to explain how these signatures can be used to detect rotor/stator faults. And finally the performance of each technique based on the sensitivity to fault severity, the effect of motor loading, and cost required for the practical implementation is discussed.
