sf6 circuit breaker Charging for sale

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.
