  • SF6 Gas Detection For HV GIS Switchgear - Crowcon F-Gas Detector

    Sep 30, 2020 · SF6 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 SF6 being an inert gas during normal use, when electrical discharges occur through the operation of high voltage equipment insulated with SF6, highly toxic by-products are produced that pose a serious health threat to workers.

  • Sulfur hexafluoride circuit breaker - Wikipedia

    Compared with air-blast breakers, operation with SF 6 is quieter and no hot gases are discharged in normal operation. No compressed-air plant is required to maintain blast air pressure. The higher dielectric strength of the gas allows more compact design or a larger interrupting rating for the same relative size as air-blast circuit breakers. This also has the desirable effect of minimizing size and weight of the circuit breakers, making foundations and installation less costly.
