SF6 Decomposition quality for Ultra High Voltage

SF6 Decomposition quality for Ultra High Voltage

Abstract. Sulfur hexafluoride (sf6) is widely used as a tracer gas because of its detectability at low concentrations.This attribute of sf6-gas allows the quantification of both small-scale flows, such as leakage, and large-scale flows, such as atmospheric currents. sf6-gas 's high detection sensitivity also facilitates greater usage efficiency
