Get PriceAs for the tripping at low-low - I would not consider low-low to be near a point where there is "low or no SF6". Especially the NO SF6 part. I agree, at low-low they will still trip adequately; if they didn't then the low-low point would be too, well, low. There were some comments above about a breaker being operated at near atmospheric pressure -We alarm on low pressure and block action on low low pressure.1As is standard, but once in low or low low pressure do you have relaying do an automatic buss trip or have SCADA take the breaker out of service?
