  • "Hissing sound" in SF 6 Gas insulated HV Switch Gear

    After component replacement, installation of new SF6 gas and other repairs, re-run the Hi-Pot test to confirm that the switchgear is able to withstand voltages at least 50% greater than the name-plate rating. Of course all of this advice is worthless if the unit has already failed. Remember that a Hi-pot is actually a destructive test.

  • Influence of biogeochemical reactions on inert gas fluxes

    Plants are grown at the top of the column. An inert gas (SF6) is injected at the bottom and its flux is continuously monitored at the surface. A similar experimental setup is run without plants. Effects of watering, daytime/nighttime plant activity, cut out of leaves, plant destruction as well as of other solicitations are determined and discussed.

  • Myth About SF6 Gas In Electrical Equipment

    May 25, 2020 · In several cases SF6 switchgear is the only possible solution: for wind power plants (offshore), in caverns, for large generator circuit-breakers, and for extensions of existing installations. This often allows existing buildings use to be extended where switchgear replacement or extension to meet load growth is needed.

  • Have you Heard of the Most Powerful Greenhouse Gas we Know

    Meet SF6, CO2’s Larger CousinWhat Is This Crazy Gas Used for?Why Is SF6 Not Banned Yet?What’s The Effect on Humans?Are There Any Alternatives Out there?Among all the greenhouse gases that exist, CO2 gets the most attention. Today, we bring a different perspective. Think about everything that you know about CO2 and multiply it by roughly 24,000. This is how much a gas called SF6 (sulphur hexafluoride) is stronger than CO2 in terms of global warming potential.You read right: SF6 is the most potent greenhouse gas in existence with a global warming potential of 23,900 times the baseline of CO2. It means that one tonne of SF6 in the atmosphere eq...
