The signal generated by partial discharge is picked up by UHF antenna and spectral analyzer, and the data are transfered to the computer for analysis by GPIB. A commonly defect in GIS was constructed in order to examine this system.

• 用特高频天线和频谱分析仪采集局放信号,通过GPIB卡传送给计算机进行分析处理,并在GIS中构造了一种常见的故障类型,对该系统进行了验证。
