  • SF6-free Innovative technology for greater sustainability

    Air has no global warming potential (GWP), no sole-source supply, and is sustainable by nature. Air-based technology is reliable and future-ready, free from regulatory considerations. To enable the change from SF6, Schneider Electric has combined air for insulation and vacuum technology for arc interruption.

  • Ventilation Measurements Using Sulfur Hexafluoride (SF6

    Mar 20, 2019Another use of SF6 is as a leak detector in closed air systems—and even leaks in an open duct system. It is important to note that a Photo-Ionization Detector (PID) cannot be used to detect SF6 since the ionization potential of SF6 is above the detection range of the standard detector and even the expanded range detector of the PID.
