MLP neural network-based decision for power transformers fault diagnosis using an improved combination of Rogers and Doernenburg ratios DGA
TL;DR: The test results indicate that the developed preprocessing approach can significantly improve the diagnosis accuracies for power transformer fault classification and the proposed combination of Rogers and Doernenburg ratios DGA methods can generalize better than other MLPNN models.
Journal ArticleDOI
Brushless Three-Phase Synchronous Generator Under Rotating Diode Failure Conditions
TL;DR: In this article, the spectral response faced with each fault condition, and an original algorithm for state monitoring of rotating diodes was proposed, given experimental observations of the spectral behavior of stray flux.
Journal ArticleDOI
Support vector machine based decision for mechanical fault condition monitoring in induction motor using an advanced Hilbert-Park transform.
TL;DR: An original fault signature based on an improved combination of Hilbert and Park transforms is suggested, which can create two fault signatures: Hilbert modulus current space vector (HMCSV) and Hilbert phase current spacevector (HPCSV).
Journal ArticleDOI
An improved combination of Hilbert and Park transforms for fault detection and identification in three-phase induction motors
TL;DR: In this article, the authors proposed an improved combination of Hilbert and Park transforms to release two fault signatures: Hilbert modulus current space vector (HMCSV) and Hilbert phase current vector (HPCSV), which were subsequently analyzed using the classical fast Fourier transform (FFT).
Journal ArticleDOI
EEMD-based notch filter for induction machine bearing faults detection
TL;DR: The achieved simulation and experimental results clearly show that the proposed approach is well suited for bearing faults detection regardless the rank of the intrinsic mode function introduced by the fault.
