Scope of Application This 100-1200 kV gas-filled, no-partial discharge combined electrical test device is suitable for dielectric withstand voltage testing, partial discharge testing, and GIS transformer accuracy testing of high-voltage, large-capacity GIS and GIL power equipment. It is an essential device for GIS substations, GIS and GIL power equipment manufacturers, and manufacturers of pot insulators and insulating structural components for preventive and factory testing. Adding a high-voltage bushing port to this device allows high voltage to be extracted, enabling various high-voltage tests on conventional high-voltage equipment. Key Features 1. High voltage is fully enclosed in a...
