sulphur hexafluoride DETERMINATION for Transformers

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 sf6 gas gas-insulated switchgear through arcing in moist or impure sf6-gas gas. Testing the gas for impurities will therefore indicate potential issues with the switchgear.
