Concerns the re-use of sulfur hexafluoride (SF6) after removal from electrical equipment (for maintenance, or at the end of life). This standard recommends procedures for reclaiming used SF6 and for restoring its quality to an acceptable level, which would allow the filling of new or existing electrical equipment.
Microsense IR SF6 Service for gas measurementSF6 gas measuring devices are used to measure the volume percentage of gas concentration in air, nitrogen, and gas mixtures. In order to do so, these devices measure gas purity that is important to maintain the dielectric property for arc quenching in circuit breakers.
Gas-insulated switchgear. The Siemens Energy range of gas-insulated switchgear (GIS), for rated voltages from 72.5 kV up to 550 kV, is an extremely successful product concept. Since its introduction back in 1968, Siemens Energy has installed switch fields in all climatic zones of the earth, recording over 420,000 years of operation since.
Sulfur hexafluoride - Wikipedia 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
