Low SF6 action - Electric power & transmission

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.
