sf6 circuit breaker determination concordegas in Canada

I can say that all the dead-tank SF6 breakers I've worked with (mitsubishi, siemens, abb) at the 115kV or higher level all trip themselves out on low-low gas. Avoiding this would require modifying the manufacturers wiring from what I've seen. It's kind like messing with an old oil breaker anti-pump or anti-slam scheme. You just wouldn't do it.
