| Abstract: | This article introduces the principle of fast wavelet transformation （FWT） based on multiresolution analysis and discusses how to use its principle to deal with the data of dielectric loss angle measured by the on-line power monitoring device. On these bases, a comparison between wavelet transformation and FFT was made. The results of simulation show that the wavelet transformation has a better filtering effect on the instantaneous disturbance and white noise. Besides, the error is also comparatively smooth. |
