THE PULSE AND THE FREQUENCY ANALYSIS METHODS FOR MONITORING THE WINDINGS CONDITION OF THE ELECTRICAL MACHINES

The article describes the main causes of internal damage to the electrical machine windings. Two fault diagnosis method windings: pulse method and frequency analysis method are reviewed. Method for converting signals from the time domain to the frequency domain using a discrete Fourier transform is shown. The results of experiments using these methods are presented. The main advantages and disadvantages of these diagnosis methods are identified.
