摘要
采用特高频(UHF)电磁波测量、常规局部放电测试以及相位测试等方法分析模型 GIS中电晕放电特征,为判断电晕放电的强度提供了一种新的方法。通过常规局部放电测试与 UHF特高频局部放电测量结果对比,可估计UHF信号所对应的放电量。
The measurement includes the UHF detection, conventional partial discharges (PD) measurement and the power phase analysis. The corona discharge characteristic of model GIS is researched. A new method for estimating degree of the corona discharges is put forward. Then discharge level of UHF signal is estimated based on comparison of UHF detection and the conventional PD measurement.
