  • Sulfur Hexafluride (SF6) Replacement or Reduction in High

    Research Institution. N/A. Abstract. Sulfur hexafluoride (SF6) is currently used in high voltage switchgear and airborne radar systems to prevent arcing between electrical contacts. SF6 is potentially damaging to the environment; solutions to the challenge of SF6 replacement in airborne radar systems are proposed with a high probability of success. Permanent gases with the desirable electron attachment properties will be evaluated and are predicted to be more effective than SF6 used at lower

  • Leak Testing High Voltage Switchgear - LACO Technologies

    May 14, 2015 · LACO Technologies. In this article we will cover production leak testing of gas insulated high voltage switchgear and associated subassemblies. Gas-insulated high voltage switchgear typically use a sulfur hexafluoride (SF6) gas to minimize arcing when the circuit breaker is activated. Leak testing of the subassemblies and finished product provide confidence that the sufficient pressurized SF6 gas will be contained inside the unit to prolong its functional life.
