Concept for insulating gas-free transmission and distribution of

In electrical energy technologies, the gas sulphur hexafluoride (SF 6) currently plays a key role as an insulating and arc-quenching medium, particularly in switchgear. In addition to its many advantages in terms of technical properties, SF 6 has the disadvantage of having a very high global warming potential (GWP). It is the most potent greenhouse gasGet price

NDIR SENSORS FOR sf 6 MEASUREMENT

sf6 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 sf 6 quantities in indoor air.Get price
