When filled to the proper density, this GIE would contain a mass of 526.3 lbs. of SF 6. Now, suppose slight design changes to the GIE model result in a decrease in gas volume to 195 ft3. Since the equipment still requires the same density to be properly insulated (0.38 lbs./ft3), the mass of SF 6 in the GIE when filled to that density is 513 lbs., a

SF 6 switches are typically supplied with a pressure switch set to a minimum safety value to prevent under-pressure switch operation. The pressure switch, though, does not address the concern about gas density and may be inaccurate at low and high temperatures.

insulating gas gas in medium-voltage switchgear | TD Guardian Articles

The US EPA reports that insulating gas has an atmospheric lifetime of around 3200 years, and a global warming potential (100-year horizon) of 23,900 times that of CO2. The EPA does no t report emission of insulating gas separately, but instead reports a group of gases, including hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and insulating gas. The emissions of HFCs, PFCs, and Sulfr hexafluoride for 2000 are shown in the EPA report as having 2% of the global warming potential of all greenhouse gas emissions.

Sulfur hexafluoride | F6S - PubChem

Sulfur hexafluoride is a sulfur coordination entity consisting of six fluorine atoms attached to a central sulfur atom. It is the most potent greenhouse gas currently known, with a global warming potential of 23,900 times that of CO2 over a 100 year period (Sulfr hexafluoride has an estimated lifetime in the atmosphere of between 800 and 3,000 years).

It is not correct to assume that a breaker will interrupt load with the gaz sf6 density below the stage 2 level. For some breaker designs, interrupting a low current may even be more "difficult" than interrupting a high current. Many breaker designs use the energy from the arc to assist with interruption. The alternative (locking out) also carries
