Abstract :
One of the most frequently used fault detection methods for induction motor is the current signature analysis. This technique depends upon locating by finite element method and analysis of specific harmonic components in the line current produced by unique rotating flux components caused by faults such as broken rotor bars. The motor current signature analysis method can detect these problems at an early stage and thus avoid secondary damage and complete failure of the motor.
