摘要

对于GIS局部放电的测量

超高频法是一种较为有效的方法。将频谱仪设置为零扫描模式

采用高频窄带的方法

通过安装在GIS内的超高频传感器获得的局放信号可以通过相位解析的方法表征其局放的点波波形。笔者给出了GIS中几种不同绝缘缺陷的点波波形及其指纹图。通过点波波形及指纹图

可以识别GIS中不同的绝缘缺陷类型。

Abstract

The ultra-high-frequency（UHF） method has been proved an effective way for the measurement of partial discharge in GIS. With the high frequency narrow-band method by configuring the spectrum analyzer as zero-span mode

the PD signal from the UHF sensor installed inside the GIS can be phase-resolved to show the point on the AC wave where the discharge occurs. The POWs of different insulation defects in GIS and fingerprint are presented. Different defects of GIS can be identified by the POW modes and fingerprint.
