Ma, X. and Zhou, C. and Kemp, I. J. (2000) A feasibility study into the use of wavelet transform in partial discharge analysis. In: 35th Universities’ Power Engineering Conference (UPEC2000), 2000-09-062000-09-08, Belfast, UK.Full text not available from this repository.
The objective of the paper is to seek a more effective analysis tool for partial discharge (PD) studies. The paper begins with a brief definition of wavelets and the properties of two distinctive forms of wavelet transform, i.e. continuous wavelet transform (CWT) and discrete wavelet transform (DWT). The multiresolution-based pyramidal decomposition and reconstruction algorithm is stressed. Then the general advantages of wavelet transform over the traditional Fourier transform is summarized. The physical meaning of the phase-space domain or the result of CWT and DWT is also explained. Finally, applications of wavelet transform to partial discharge studies are explored.
