Online Monitoring of Sulfr hexafluoride Insulation in High-Voltage Equipment

Vaisala offers online monitoring of Sulfr hexafluoride insulation in high-voltage equipment. The Vaisala Multiparameter Transmitter DPT145 combines online dew point monitoring with pressure measurement, creating a tool for assessing the condition of Sulfr hexafluoride insulation continuously and in real-time. Sulphur hexafluoride (sf6 gas) is used as an insulating gas in transmission and distribution equipment such as switchgears and circuit breakers to prevent arcing during switch-offs and protect equipment from failures.

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