SF6 decomposition monitorand record for middle voltages

sf6 gas switchgear Collection detecting. Dec 04, 2017Gas-insulated switchgear (GIS) is a common electrical equipment, which uses sulfur hexafluoride (SF6) as insulating medium instead of traditional air. It has good reliability and flexibility. However, GIS may have internal defects and partial discharge (PD) is then induced.
