常规的PD电气测量是用连接到工厂的检测器进行的。本文介绍了与国家电网公司和无线电通信机构合作进行的研究，通过一种新的非接触式数字方法对局部放电源进行辐射检测。该设备使用天线传感器和参考电压输入，直接在2.5 GHz采样。高压实验室测试，包括空气，SF6和油排放的结果。结果包括波形、平均频谱和脉冲数分布。一个建议是从这些不同的击穿效应的基础上分析的频谱和脉冲计数分布的记录脉冲的特性。
Conventional electrical measurements of PD are performed with detectors connected to the plant. This paper describes research conducted in conjunction with the National Grid Company and the radiocommunications agency for the radiometric detection of partial discharge sources via a novel noncontact digital method. The equipment uses an antenna sensor and reference voltage inputs which are directly sampled at 2.5 GHz. Results for hv laboratory tests involving air, SF6 and oil discharges are presented. The results include the waveform, average frequency spectrum and pulse count distribution. A proposal is made for the characterisation of the recorded impulses from these different breakdown effects based on analysis of the spectra and pulse count distributions.
