  • Why SF6 Gas used in HV/EHV Circuit Breaker? | Electrical

    Apr 28, 2018Arc Extinction in SF 6 Circuit Breakers:. 1) During the arcing period, SF 6 gas is blown axially along the arc. The gas removes the heat from the arc by axial convection and radial dissipation. 2) Due to its electronegativity, and low arc-time constant, the SF 6 gas regains its dielectric strength rapidly after the final current zero; the rate of rise of dielectric strength is very high.
