SF6 Gas reducing system

SF6 Gas reducing system

SF6 is widely used as an insulating and arc quenching gas in medium and high voltage transformers. As equipment ages, it is being repaired or replaced with more efficient equipment which typically uses 1/3 the quantity of SF6. This creates a need to recover the SF6 for recycling or disposal.

  • What is SF6 Circuit Breaker? Construction, Working

    The SF 6 gas absorbs the free electrons in the arc path and forms ions which do not act as a charge carrier. These ions increase the dielectric strength of the gas and hence the arc is extinguished. This process reduces the pressure of the SF 6 gas up to 3kg/cm^2 thus; it is stored in the low-pressure reservoir. This low-pressure gas is pulled back to the high-pressure reservoir for re-use.
