    The use of sulphur hexafluoride in place of solid and liquid insulators offers a number of important advantages: High dielectric strength at lower cost When pressurized, sulphur hexafluoride can exhibit the same dielectric strength as liquid insulators. However, the per-unit-volume cost of SF 6 is only a fraction of that of liquid dielectrics.

    Abstract. Sulfur hexafluoride (SF 6) is widely used as a tracer gas because of its detectability at low concentrations.This attribute of SF 6 allows the quantification of both small-scale flows, such as leakage, and large-scale flows, such as atmospheric currents. SF 6 s high detection sensitivity also facilitates greater usage efficiency and lower operating cost for tracer deployments by
