概述了局部放电超高频检测方法的发展及其在GIS和电力变压器中的应用现状,简要介绍了超高频局部放电检测系统的构成,着重对不同层次的超高频检测法的标定进行了阐述。同时,对近年来国内外关于超高频法标定的研究工作做了评述,并就进一步深入研究提出了建议。
This paper outlines the application status of partial discharge UHF detection for GIS and power transformers, and construction of the UHF PD-detection system mainly used now are simply introduced. Calibration methods for UHF signal detection system are expounded from different levels. And, recent research work about calibration for UHF method is evaluated, then, suggestion is proposed for next research.
