sf6 circuit breaker Indicator National Field Services in Denmark

I'm used to the breaker tripping itself out for low-low SF6. What type of breaker are you using? I'm thinking all of your discussions have been moot as the breaker will not wait for a trip signal on low-low SF6. I suggest you really go through the breaker control circuit to see how it behaves on its own. It will trip itself.
