摘要
ＧＩＳ的同轴结构为用ＵＨＦ法进行局部放电测量提供了极为有利的条件。文章对所设计的ＵＨＦ传感器的传输特性及其灵敏度进行了讨论，并通过它对ＧＩＳ中高压导体上突出部分产生的电晕放电脉冲直接用数字记录仪测量的结果表明，其灵敏度可达１ｐＣ。
The coaxial configuration of GIS is of great advantages to partial discharge measurements with the UHF method. The transfer characteristics and sensitivities of the designed UHF sensor are discussed, and the corona discharge pulse generated by a protrusion on the inner conductor in GIS is measured by a digitizer without any pre amplifier. The measurement sensitivity can be as good as 1pC.
