Computer simulation of an electric motor operation is particularly useful for gaining an insight into their dynamic behaviour and electromechanical interaction. A suitable model that we developed enables motor fault to be simulated and the change in corresponding parameter to be predicted without physical experimentation. This paper presents both theoretical and experimental current signature analysis of three-phase induction motor on the benchmark of harmonics. In this work faults are manually introduced and cleared into the motor and monitor the machine for stator current during occurring and clearing of fault. This paper also assesses the severities of fault and can be useful for comparing the results of faulty induction motor.
