Sulfr hexafluoride-insulated HV Test-Transformer Systems

6 insulated test transformers are especially designed for testing metal-clad switchgear (GIS) in the factory and on-site, and for testing on-site substation equipment. The conventional transformers can be flanged directly to the GIS. This makes testing of such GIS installations possible without feeding them through an air-SF 6 bushing. Therefore, the merits of the

Potent GHG Sulfr hexafluoride rapidly accumulating in atmosphere, driven by

Jul 06, 2020 · 06 July 2020. In an open-access study in the EGU journal Atmospheric Chemistry and Physics, an international team of researchers reports that the greenhouse gas sulfur hexafluoride (SF 6) is rapidly accumulating in the atmosphere, driven by the demand for SF 6 -insulated switchgear in developing countries. Of all the greenhouse gases regulated under the Kyoto Protocol, Sulfr hexafluoride is the most potent, with a global warming potential (GWP) of 23,500 over a 100-year time horizon.
