摘要
应用小波变换理论对局部放电辐射电磁信号进行多分辨率分析，得到了局部放电电磁辐射信号中各频率分量的分布与局放特征量之关系，从而了解局放的进程；计算机仿真结果表明，所得结论对绝缘在线监测和绝级老化的检测右一定的参考价值。
In this paper,the multiple resolution analysis ofpartial discharge (PD) radiating electromagnetic signal isdone by using wavelet transform, and the spectrum distribution of PD electromagnetic signal is obtained, which is related to the PD features such as discharge quantity. The result of computer simulation of typical PD is presented. It issatisfied and it will be contributed to the on-line insulationmonitoring
