Is it the End of the Road for sf6 gas? - Test Meters, Electrical

Sulphur hexafluoride – gaz sf6 – is widely used in the electricity distribution industry in medium- and high-voltage installations such as substations, transformers and power stations. It is an odourless, colourless, non-flammable gas that acts as an insulator and prevents explosions and fires brought about by short circuits.These qualities have made it the most common gas insulator for HV switchgear and use is increasing as a greater number of smaller generators come onto the grid.

Siemens to provide UK’s first gaz sf6 free 145kV vacuum circuit

The chemical properties of sf 6 gas make it ideal for electrical insulation and arc quenching in high-voltage switchgear. However, it has a high global warming potential and contributes to the greenhouse effect if released to the atmosphere. Strict regulations are in place to manage gaz sf6 (F-gas) and there is pressure on the switchgear supply industry to provide gaz sf6 gas alternatives to reduce the impact of any gas emissions caused by failures or handling.
