  • 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
