- What is a GIS partial discharge?
GIS (gas-insulated switchgear) may produce discharge phenomenon in the local area during operation, which is affected by factors such as insulation aging, manufacturing defects, installation errors or metallic foreign objects. Although localized discharge may not cause immediate failure, it will continue to damage the insulation structure and is an important precursor of GIS insulation accidents. - Why do you need GIS partial discharge online monitoring system?
