Journal ArticleDOI
Diagnosis and classification of stator winding insulation faults on a three-phase induction motor using wavelet and MNN
TL;DR: In this article, the authors proposed a robust technique to detect, classify various stator winding insulation faults and severity of stator inter-turn faults when an induction motor works under various operating conditions.
Proceedings ArticleDOI
Wavelet ANN based stator internal faults protection scheme for 3-phase induction motor
TL;DR: In this article, the wavelet decomposition of three-phase stator currents is carried out with Bior5.5 and the normalized peak d1 coefficients of these currents are fed to a feedforward neural network to classify various faults.
Proceedings ArticleDOI
A transient current based bus zone protection scheme using wavelet transform
TL;DR: In this paper, the authors deal with the application of wavelet transform for the detection of busbar faults and providing backup for external faults in the event of internal faults, the transient behavior of feeder and zone-2 currents is opposite to that of zone-1 source current and the corresponding currents exhibit similar transient behavior as that of source current.
Proceedings ArticleDOI
Wavelet — ANN based fault diagnosis in three phase induction motor
TL;DR: In this paper, the authors proposed a protection scheme based on Wavelet Multi Resolution Analysis and Artificial Neural Networks which detects and classifies various faults like Single phasing, Under voltage, Unbalanced supply, Stator Turn fault, Stators Line to Ground fault, STator Line to Line fault, Broken bars and Locked rotor of a three-phase induction motor.
Proceedings ArticleDOI
Detection and identification of stator inter-turn faults in three-phase induction motor in presence of supply unbalance condition
TL;DR: In this article, a wavelet multi-resolution analysis based approach was proposed for detecting and identifying the stator inter-turn faults in the presence of supply unbalance, where the flag count reached 6 over a moving window of 10 samples.
