People who carry out work in connection with sulphur hexafluoride (SF 6) gas must now be specifically trained and certified. Among the relevant activities, in particular, are: Installation, service, maintenance, repair or shutdown of gas-insulated electrical switchgear Performing leak testing on plants that fall under the F-gas regulation

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 (SF6 has an estimated lifetime in the atmosphere of between 800 and 3,000 years).

Sulfur hexafluoride (SF 6) or sulphur hexafluoride (British spelling), is an inorganic, colorless, odorless, non-flammable, non-toxic but extremely potent greenhouse gas, and an excellent electrical insulator. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. It is a hypervalent molecule.Typical for a nonpolar gas, it is poorly soluble in

and sustainable management of sulfur hexafluoride (SF 6) at DOE sites. SF 6 is an extremely potent greenhouse gas. BACKGROUND Sulfur hexafluoride is a colorless, odorless, non-toxic synthetic gas commonly used to insulate electrical equipment. Equipment such as circuit breakers, current-interruption equipment, transmission lines, transformers,

Working of SF6 Circuit Breaker. The working of an SF6 circuit breaker is similar to the working of a normal circuit breaker we discussed in previous articles. In the closed position of the breaker, the contacts remain surrounded by sulphur hexafluoride gas (SF6) gas at a pressure of about 2.8 kg/cm 2.

A circuit breaker in which SF6 under pressure gas is used to extinguish the arc is called SF6 circuit breaker. SF6 (sulphur hexafluoride) gas has excellent dielectric, arc quenching, chemical and other physical properties and has proved its superiority over other arc quenching mediums such as oil or air. The SF6 circuit breaker is mainly divided into three types

History of SF6

The cumulative exposure for an 8-hour work shift shall be computed as follows: E = (C a T a +C b T b +...C n T n) ÷ 8 Where: E is the equivalent exposure for the working shift. C is the concentration during any period of time T where the concentration remains constant. T is the duration in hours of the exposure at the concentration C.

Operating principle. Current interruption in a high-voltage circuit breaker is obtained by separating two contacts in a medium, such as sulfur hexafluoride (SF 6), having excellent dielectric and arc-quenching properties. After contact separation, current is carried through an arc and is interrupted when this arc is cooled by a gas blast of sufficient intensity.

Equipped with non-dispersive infrared technology (NDIR), the SF6 transmitter detects sulfur hexafluoride quickly and reliably even in the ppm range in ambient air. The optical measuring technology works according to a physical measuring principle – without chemical reactions or wearing parts.
