Sulfur Hexafluoride SF6 - A-Gas allows simplified design of high and medium voltage switchgears because of size and weight reduction, quiet and reliable handling and maintenance. The emission of one kilogram of SF6 is in terms of share of the greenhouse effect is equal to 23.500 kg CO2 emissions. (=38 car emissions /yr.).
FLIR GF306 SF6 Optical Gas Imaging Camera | FLIR Systems FLIR GF306 optical gas imaging camera visualizes sulfur hexafluoride (SF6) and other gas emissions without the need to shut down operations. SF6 is used in the electric power industry as an insulator and quenching medium for gas-insulated substations and circuit breakers. The portable, non-contact GF306 allows you to quickly scan substations for leaks while maintaining a safe distance from ...
Myth About SF6 Gas In Electrical Equipment· 3. Is SF6 harmful for the environment? It has no ecotoxic potential, it does not deplete ozone. Due to its high global warming potential of 22.200 (*) it may contribute to the man made greenhouse-effect, if it is released into the atmosphere. However in electrical switchgear the SF6 gas is always used in gas-tight compartments, greatly minimising leakage.
