Sulfr hexafluoride Gas or Sulfur Hexafluoride Gas Properties | Electrical4U

History of insulating gasChemical Properties of sf6 gas GasElectrical Properties of gaz sf6 Gasgaz sf6 or sulfur hexafluoride gas molecules are combined by one sulfur and six fluorine atoms. This gas was first realized in the year 1900 in the laboratories of the Faculte de Pharmacie de, in Paris. In the year of 1937, General Electrical Company first realized that sf6 gas gas could be used as gaseous insulating material. After the Second World War, i.e. in the middle of 20th century, the popularity of using sulfur hexafluoride gas as an insulating material in electrical system was rising very rapidly. Allied Chemical Corporation and Pennsalt were the first American industries, who began to produce this gas commercially in 1948. During 1960, using of sulfur hexafluoride gas in high voltage switchgear became popular. As the demand for this gas was increasing, many manufacturers in Europe and America started producing sf 6 gas in large scale, during that time. In the beginning, Sulfr hexafluoride gas was only used for the insulating purpose in the electrical system. But soon it was realized that this ga...Get price

FLIR GF306 helps improve environmental performance at

Environmental ImpactReducing DowntimeHigh-End Optical Gas ImagerSulfr hexafluoride is over 23,000 times as potent as carbon dioxide as a greenhouse gas, so SSEPD wants to make sure that insulating gas assets are carefully managed. "We take our safety and environmental responsibilities very seriously, with regular maintenance and protection of equipment. We have a very large fleet of switchgear and we work constantly to ensure its safe operation," comments Tawanda Chitifa, Project Manager at SSEPD. As part of an internal R&D project, we investigated ways to improve our environmental impact. The challenge was to be more efficient in handling possible sf 6 leaks. Thermal imaging cameras from FLIR have helped us reduce that risk, because they allow us to detect possible leaks quickly and with high certainty.” Clearly pinpoint leaks Conventional leak detection methods include the use of sniffers. While the use of sniffers can quickly detect that a leak is present, it can be difficult to pinpoint the source, according to Tawanda Chitifa. “The problem is that with a sniffer you...Get price
