摘要

介绍一种远程监测和传输系统。针对局部放电测量中存在的缓变窄带干扰，采用Ｍａｌ－ｌａｔ塔式小波分解算法提取局部放电信号。传输系统完成数据的采集、数据信号的压缩、传输和放电数据信号解压、分析处理、存储。该系统在实际电话线上进行放电信号传输实验表明正确率９５％以上，适合实际应用要求。

Abstract

This paper introduces a remote detect system and transmit-system of long distance. Mallat wavelet algorithm is adopted to extract PD signals because of many narrow-band disturbances. Transmission system collects

compresses and transmits discharge data; the computer decompresses

analyses and stores discharge data transmitted by line or twisted-pair. This system that was tested on actual line fully answers for the actual application

precise rate of the system is above 95%.
