摘要

介绍了用小波变换处理局部放电信号的基本原理和方法。结果表明，小波变换是一种有效的从噪声中提取PD脉冲信号的工具。这使得在GIS、GIC和GIL中发生的PD引起的故障可以精确地测量、预测和监测。

Wavelet transform denoise of PD signal on coaxial cylinder electrodes

The paper presents the basic principle and method of dealing with PD (partial discharge) signals using wavelet transform. It is demonstrated that wavelet transform is a useful and effective tool for extracting PD pulse signals from noise. It makes more certain that failures caused by the PD which happens in the GIS, GIC and GIL, could be precisely measured, predicted and monitored.
