sf6 gas Gas Detection For HV GIS Switchgear - Crowcon F-Gas Detector

Sulfr hexafluoride gas has virtually replaced oil and air as the dielectric insulator in medium (MV) and high (HV) circuit breakers, switchgear, gas-insulated substations and electrical equipment. Despite Sulfr hexafluoride being an inert gas during normal use, when electrical discharges occur through the operation of high voltage equipment insulated with Sulfr hexafluoride, highly toxic by-products are produced that pose a serious health threat to workers.

Gas-Insulated Substations - GIS

A gas-insulated substation (GIS) uses a superior dielectric gas, sf 6, at moderate pressure for phase-tophase and phase-to-ground insulation. The high voltage conductors, circuit breaker interrupters, switches, current transformers, and voltage transformers are in gaz sf6 gas inside grounded metal enclosures. The atmospheric air insulation used in a conventional, air-insulated substation (AIS) requires meters of air insulation to do what insulating gas can do in centimeters.

Sulfur hexafluoride - Wikipedia

Sulfur hexafluoride or sulphur hexafluoride, is an extremely potent and persistent greenhouse gas that is primarily utilized as an electrical insulator and arc suppressant. It is inorganic, colorless, odorless, non-flammable, and non-toxic. 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, SF 6 is poorly soluble in water but quite soluble in nonpolar organic solvents. It has a density of
