  • SF6 Circuit Breakers - TestGuy

    SF6 has a number of advantages for use as an insulator. The dielectric strength of SF6 increases with pressure so smaller breakers can be used at higher voltages. The breakers have a smaller footprint, so they use less real estate which can be very expensive.

  • MANAGEMENT AND SAFE HANDLING PROCEDURES

    Bureau of Reclamation facilities have many circuit breakers containing SF6 gas as an insulating medium. SF6 has been identified as a greenhouse gas that may be responsible for global warming. Release of SF6 gas into the atmosphere during maintenance work or an accident must be reduced, tracked, and reported to the EPA.

    Feb 02, 2009I have a large collection of papers about SF6 circuit-breakers, but I am not clear what you need. If the circuit-breaker has failed it may or may not have released arced SF6 into the substation. If Arced SF6 has been released there are toxic hazards associated with this, and I hope that you have had the site cleaned up professionally.

  • How Circuit Breakers Ensure Safety Reliability of Power

    Current interruption in a high-voltage circuit breaker is obtained by separating two contacts in a medium of sulfur hexafluoride (SF6), having excellent dielectric and arc-quenching properties. After contact separation, current is carried through an arc and is interrupted when this arc is cooled by a gas blast of sufficient intensity.
