  • Opening of 132kV Breaker with Very Low SF6 Pressure -

    Feb 14, 2012Opening a completely isolated SF6 breaker with very little or no SF6 gas (as if it were in a testing lab) would pose no threat to the health of the breaker. There is no auto-trip feature. I think auto-trip at such low gas pressure may not be desirable because arcing might start across the open contacts of breaker due tobid

  • Ultra-Trace Analysis Technique for SF6 Using Gas

    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 efficiencybid
