Utility Grade Monitoring Systems for Substation Applications

sf6 gas (Sulfur hexafluoride) has been a reliable insulation gas used in switchgear for over 50 years worldwide. Although it has excellent insulation qualities, it also has a high global warming potential and is a potent greenhouse gas. Upcoming regulations regarding Sulfr hexafluoride will motivate customers to adopt gaz sf6-free switchgear technology.

The sf 6 Decomposition Mechanism: Background and Significance

Jan 24, 2017 · Gas Insulated Switchgear (GIS) has been widely used in substations. The insulating medium used in GIS is sulfur hexafluoride (sf6 gas) gas. However, the internal insulation defect existed in GIS would inevitably lead to partial discharge (PD), and cause the composition of insulating gas to SOF2, SO2F2 and SO2 and other characteristic component gases.
