I'm doing research on fault detection ,classification and identifying ,I have found out fault detection using wavelet analysis need a guide about other methods.
You can use either a simple Decision Tree / Random forest / Support Vector Machine / Fuzzy Logic / Artificial Neural Network / Adaptive Neuro Fuzzy Inference System for the classification. But before that extracting the features extracting features from the electrical signals is necessary by doing fast fourier transforms and wavelet transforms. But these transforms will increase the computational overhead of the classification model.
