摘要

现有的局部放电测量技术主要有窄带测量和超宽带测量两种。超宽带测量可以获得更多更真实的有用信息并能提高测量的信噪比 ;而窄带测量因其应用和研究的广泛性已积累了丰富的经验

提出了许多诊断和分析的方法

因此同时进行窄带和超宽带测量有助于获得更多的信息

更好地利用已有研究成果。而消除和抑制测量现场的干扰是有效测量的前提

本文总结了试验中采取的回路抗干扰的措施

Abstract

Two main measuring techniques

narrow band detection and ultrawide band（UWB）detection

are generally applied in partial discharge （PD） measurement.It will help to achieve more reliable and useful information and higher signal to noise ratio with UWB detection than narrow band detection.Whereas

it has been abundant experience with narrow band detection

so it is a good idea to detect PD simultaneously with narrow and ultrawide band method. Moreover

based on the relations between the detected results of the two techniques

it will help to use the research results effectively that already existed. Rejecting and suppressing on site interference is the precondition of PD measurement. Some measures of interference rejection are given in this paper.
