Current signature analysis is used successfully for induction motor fault detection. A common mathematical tool for assessing fault signals is the wavelet transform. However, choosing the right mother wavelet is the main challenge with wavelet analysis. Additionally, selecting the best level of disintegration is crucial since as the level of disintegration rises, so do the complexity and computation time. In order to get a result that is noticeably accurate while maintaining a minimal degree of complexity, we have developed a system for appropriate mother wavelet selection and level of disintegration for current based fault analysis of 3 phase induction motor. Here, we have used mother wavelets from the symlets (Sym), coiflets (Coif), and daubechies (db) groups to assess the data and deconstruct 3-phase induction motor fault current signals up to 5 levels. The loading of motor has also been varied in 3 distinct steps. We have also examined the four main quality metrics-signal to noise ratio (SNR), correlation coefficient (CC), peak signal to noise ratio (PSNR) and root mean square error (RMSE)-and came to the conclusion that Symlet5 (Sym5) mother wavelet at 4th level of disintegration was the best option.
