Assessment of SF6 monitoring

Assessment of SF6 monitoring

The global warming potential of SF6 is two to four times greater than that of NF3 (SF6 is being outlawed in Europe). NF3 may require a shorter recovery step, thus reducing the amount of material consumed as well as reducing the overall time to condition the chamber.

    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
