摘　　要：带有局部放电测量的感应电压试验为GB/T 1094.3—2017《电力变压器第3部分:绝缘水平、绝缘试验和外绝缘空气间隙》标准中规定的检验项目。近年来笔者所在试验站检验的出口国外的电力变压器较多,遂根据业务发展形式,对此项目的试验方法即脉冲电流法,以及方法中涉及的参数选择、连接线、抗干扰措施和校正等方面进行了解析,希望能使相关工作人员对检验方法有更清晰的了解,同时能为企业和检验检测站对此项目进行研究提供一定的帮助。The induced voltage test with partial discharge measurement is the inspection item specified in GB/T 1094.3-2017“Power transformers-Part 3:insulation levels,dielectric tests and external clearances in air”.In recent years,the testing station where the author is located has inspected a large number of power transformers exported abroad.Therefore,based on the development of the business,the testing method for this project,namely the pulse current method,as well as the parameter selection,connection lines,anti-interference measures,cali⁃bration and other aspects involved in the method,are analyzed and understood.It is hoped that this will enable rel⁃evant personnel to have a more straightforward understanding of the testing method and provide some assistance for enterprises and inspection and testing stations to study this project.
