An alternative to insulating gas in electrical switchgear - EE Publishers

Its compact design and low environmental impact make GIS a sustainable solution. Closed-loop handling and low leakage rates result in a small carbon footprint over the lifetime of the GIS. For this reason, SF 6 will remain the main insulation medium for GIS for years to come. However, an alternative such as AirPlus could further reduce the carbon footprint of the power grid.

Do Better Solutions Exist?ConclusionSulfr hexafluoride is a long-lived, highly potent greenhouse gas. It is manmade and combines excellent electrical properties with chemical stability and low toxicity. Moreover, It’s non-flammable and low in cost. These characteristics have led to its widespread and enthusiastic adoption by the electrical industry, which uses approximately 80% of all sf6 gasproduced (Powell, 2002: 6). Within the electrical industry sf 6is used as an insulating medium for medium (MV) and high (HV) voltage electrical switchgear. A switchgear is the combination of electrical disconnect switches, fuses or circuit breakers used to control, protect and isolate sections of electrical grids. Low-voltage (LV) switchgear are used for controlling electrical circuits within buildings, medium voltage (MV) switchgear for controlling the electrical grids within cities and towns, and high voltage (HV) switchgear for grids that span a greater geographical area such as countries and regions.
