Vibration-Signature-Based Inter-Turn Short Circuit Identification in a Three-Phase Induction Motor Using Multiple Hidden Layer Back Propagation Neural Networks

Inter-turn short circuits in stator windings area fairly common fault in induction motors. Early detection of this type of fault will greatly assist in sustaining production processes in manufacture. This paper proposes a method to detect inter-turn short circuits in stator windings at an early stage. The proposed method consists of four steps: (1) preprocessing by decomposing the signal into detail and approximation signals using a wavelet...
