sf6 gas Analysis for powergrid

Abstract. Sulfur hexafluoride (sf6 gas) 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. sf6 gas 's high detection sensitivity also facilitates greater usage efficiency
