抄録
To check and protect the water-wheel generators with a much faster and simpler method during the operation, an insulation diagnostic method using an AE (Acoustic Emission) sensor has been proposed. The insulation diagnostic technique needs to separate the AE signal generated by the partial discharge from the AE signal including the machine noise. Therefore, the AE signal during the normal operation was compared to the AE signal when the rotor revolved at the non-excitation condition. Moreover, we measured the AE signal while the generator was operated normally for a long time. The AE signal were analyzed using the FFT and Wavelet processing techniques. As a result, the AE signal could be separated in to the machine noise level and the AE signal level produced by the partial discharge, and the temperature of stator winding was related to the partial discharge from the measured AE signal.
