  • Assessment of SF6 Gas Insulation | EA Technology

    Testing SF 6 gas for impurities will therefore indicate potential issues with the switchgear. Decomposition products arise during operation of SF 6 gas-insulated switchgear through arcing in moist or impure SF 6 gas. Testing the gas for impurities will therefore indicate potential issues with the switchgear. In addition, while SF 6 containers are designed to be gas-tight to ensure no environmentally hazardous SF 6 gas escapes, it is important to monitor SF 6Phone: 01513394181

  • Atmospheric SF6: Trends, Sources, and Prospects

    Sulfur hexafluoride (SF6) is the most potent greenhouse gas known. Its atmospheric concentration has increased by 2 orders of magnitude since industrial production started in 1953. Once released into the atmosphere, SF6 will only be removed exceedingly slowly due to its atmospheric lifetime of about 3200 yr. These features have brought SF6 into the climatic impact discussion aimed at reduction
