The invention belongs to the technical field of GIS partial discharge, and particularly relates to a field inspection method for GIS ultra-high frequency partial discharge sensor. The method includesthe following steps of appearance inspection, insulation performance inspection, and sensitivity inspection, has high safety and reliability, a wide application range, and can effectively inspect a situation where only one UHF partial discharge sensor is installed in the GIS or an analog signal cannot be injected through a built-in UHF partial discharge sensor. The inspection device in the invention is convenient to install and maintain, and avoids installing a large number of built-in UHF partial discharge sensors, can reduce a large amount of material resources, financial resources and manpower for power units, improve economic efficiency, and ensure the operation safety of the power equipment. The required inspection equipment is simple and convenient to arrange, and can effectively test the performance and sen
