Abstract :
This article introduces the principle of fast wavelet transformation (FWT) based on multi-resolution 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.
