advantages of SF6 insulated leak testing

Sep 30, 2020Effective monitoring and detection of these gases is essential. SF6 has a very high Global Warming Potential (GWP), 22,200 times higher than CO2. Therefore, a small amount in the atmosphere can have a large effect on global temperatures. Although SF6 is not generally considered toxic, it has an short term exposure limit of 1000ppm.

  • Panel discussion: The pros and cons of using SF6

    10 mins readJul 14, 2015As SF 6 gas is heavier than air, it will be easy for the gas to leak quickly when the damage is on the bottom. In general, the leakage rate is slow and it also takes some appreciable time for the SF 6 to disperse from the source of the leak.

  • Safety by design: solid insulated technologies challenge

    As discussed previously, SF6 has excellent insulating properties far superior to air. So, using SF6 as the insulating medium versus air requires these assemblies to be sealed from the atmosphere, thus able to function at high altitudes without any de-rating factor. Some applications require switchgear to be installed at very high elevations.
