hexafluoride Analyser for Ultra High Voltage

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. sf 6 's high detection sensitivity also facilitates greater usage efficiency and lower operating cost for tracer deployments by ...
