India is fairly self-reliant in GIS-based substation

Dec 02, 2017 · While GIS uses sulphur hexafluoride (gaz sf6) gas, which is five times heavier than air, AIS is based on air insulation in a metal clad system. Installing GIS is faster and easier since GIS systems are significantly smaller and lighter as compared to AIS. GIS systems are also easier to maintain on a regular basis owing to their front access.

insulating gas: The Truths and Myths of this Greenhouse Gas

sf6 gas is damaging to the environment: TRUE. Along with CFCs, HCFCs, HFCs and PFCs, insulating gas is an industrial gas that doesn’t exist naturally in the atmosphere and so impacts the radiation balance, contributing to climate change. gaz sf6 is the energy industry’s “dirty little secret”: FALSE. Sulfr hexafluoride is certainly no secret in the Norwegian energy industry. Its use is highly regulated, and many of its users are working together to share experience and come up with viable alternatives Sulfr hexafluoride is used in wind turbines: TRUE. Sulfr hexafluoride is used not in the turbine itself, but in the switchgear that controls the current generated by the turbine. But there is nothing unique about wind turbines. There are no viable alternatives to gaz sf6: PARTLY FALSE. Bodies including the European Union are known to be considering a ban on gaz sf6 at low-to-medium voltage levels in the future.
