Assessment of Sulphur Hexafluoride (SF6) gas insulation
Testing SF6 gas for impurities will therefore indicate potential issues with the switchgearDecomposition products arise during operation of SF6 gas-insulated switchgear through arcing in moist or impure SF6 gas. Testing the gas for impurities will therefore indicate potential issues with the switchgear. In addition, while SF6 containers are designed to be gas-tight to ensure no environmentally hazardous SF6 gas escapes, it is important to monitor SF6 gas pressure both to ensure no leaks are present and also to ensure the switchgear is adequately insulated
