25/05/2021Significantly better interruption performance in SF₆ alternatives is achieved by creating a so-called stagnation-point flow pattern of gas around the arcing zone. Further, because weak dielectric strength in both cold and hot zones in the LBS may cause restrikes, innovative solutions have been implemented to tailor the flow pattern of the hot gas to prevent arc re-ignition.[email protected]

22/05/2018However, SF6 is a greenhouse gas necessitating SF6 filled equipment being closely monitored for leaks. For this reason, GIS buses have built-in monitors and alarms to alert operators when leaks occur. It is also common to use thermal imaging, i.e. infra-red cameras, to detect leaks. In addition to switchgear,transformers are now using SF6 as well.

The high sensitivity and very small lower detection limit enable the 50 ppm sensor to detect even minimal sulphur hexafluoride leaks with absolute reliability. Another typical application for the highly sensitive FLOW EVO SF 6 sensor (50 ppm) is detection of SF 6 in environmental simulations. Since sulphur hexafluoride is not present in the
In this paper, a highly sensitive SF 6 decomposition based on fiber-enhanced Raman spectroscopy is built up. The Raman spectroscopy of COS and CF 4 was acquired. The characteristic peak of COS at 859 cm -1 and that of CF 4 at 909 cm -1 were observed respectively.

First time on market! An all new intuitive and interactive calculation tool supporting : - SF6 gas Density calculation - SF6 gas Humidity calculation
For many years, SF6 has been the preferred dielectric medium in electrical power applications, particularly in high voltage gas-insulated equipment. However, with the recognition that SF6 has an extremely long atmospheric lifetime and very high global warming potential, governments have pursued emission reductions from gas-filled equipment. The electrical power industry has responded to this

In Norway, however, BKK Nett, the country's second largest power grid owner with 245,000 customers is spearheading a shift to eliminate the gas from their substations. The company became the first to commission a Siemens Energy SF 6 -free gas-insulated switchgear (GIS) that replaces the greenhouse gas with treated air, called "clean air", a pure mixture of nitrogen and oxygen with zero potential for global warming.

The SF 6-free GIS, with zero global-warming potential, is a development based on upgraded switching and insulation technology that has long been proven in practice. And thanks to digital technology and the use of more flexible low-power instrument transformers (LPIT) rebuilds like the one in Bergen can be made in the same space as the old equipment.
odm sf6 process in Abkhazia. odm sf6 process in AbkhaziaSF6 application in high voltage switchgear manufacturers. Manufacturers of SF6 gas insulated equipment need to conduct a large number of tests during the development process, including tests in extreme environments, thus large amounts of SF6 gas have to be used.
ABB is writing the future of sustainable energy distribution by extending its SF6-free medium-voltage (MV) switchgear portfolio. Having developed a new load break switch, ABB is partnering with multinational energy company Enel to bring technology to the market that is considerably better for the environment.
12/11/2021A recent study suggests that the UK's use of SF6 has risen in recent years, and leakage levels are over 1%. It is estimated that, by 2100, appropriate controls could limit the contribution of SF6 to global warming to 0.2%. In the UK, the gas already contributes this much to its annual global warming potential.
