  • Assessment of SF6 Gas Insulation | EA Technology

    Assessment of Sulphur Hexafluoride (SF6) gas insulation. 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.
