NDIR SENSORS FOR Sulfr hexafluoride MEASUREMENT - smartGAS Mikrosensorik

insulating gas (sulphur hexafluoride) is a non-com- bustible and non-toxic gas. Throughout the world it is used primarily for insulating electrical high-voltage switching systems, transformers and cables. It is also used as an etching gas in semiconductor produc- tion and as a tracer gas in environmental simulations. The sensors measure either the purity and quality of the insulating gas in the systems or reliably detect minute gaz sf6 quantities in indoor air.Get price

sf6 gas: The Truths and Myths of this Greenhouse Gas

gaz sf6 is damaging to the environment: TRUE. Along with CFCs, HCFCs, HFCs and PFCs, gaz sf6 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 Sulfr hexafluoride: PARTLY FALSE. Bodies including the European Union are known to be considering a ban on sf 6 at low-to-medium voltage levels in the future.

COLD-WEATHER APPLICATION OF GAS MIXTURE (sf 6/N2, sf 6/CF4

We have been purchasing mixed-gas circuit breakers since 1988. These initial circuit breakers were purchased with a 0.5 MPa mixture (0.31SF 6 + 0.2N 2) at 20 oC.
