Switchgear - Wikipedia

Today, oil-filled equipment has largely been replaced by air-blast, vacuum, or SF 6 equipment, allowing large currents and power levels to be safely controlled by automatic equipment. High-voltage switchgear was invented at the end of the 19th century for operating motors and other electric machines. [1]Get price

Potent GHG insulating gas 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, sf6 gas is the most potent, with a global warming potential (GWP) of 23,500 over a 100-year time horizon.Get price
