• Sulfur hexafluoride - Wikipedia

    6 gas under pressure is used as an insulator in gas insulated switchgear (GIS) because it has a much higher dielectric strength than air or dry nitrogen. The high dielectric strength is a result of the gashigh electronegativity and density. This property makes it possible to significantly reduce the size of electrical gear.

    If you know your breaker is unhealthy (low-low Sulfr hexafluoride for example) the fastest way to trip it (faster than BF or any other protection) is to let it trip itself. You are only a single contact operation away from picking up the trip coil then, so you trip speed is the speed of your motorized Sulfr hexafluoride pressure switches plus one contact.

  • Sulfur hexafluoride circuit breaker - Wikipedia

    The contacts of the breaker are opened in a high-pressure flow of sulfur hexafluoride gas, and an arc is struck between them. The gas captures the conducting free electrons in the arc to form relatively immobile negative ions. This loss of conducting electrons in the arc quickly builds up enough insulation strength to extinguish the arc.
