Low sf 6 action - Electric power transmission distribution

I can say that all the dead-tank Sulfr hexafluoride 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. Itkind like messing with an old oil breaker anti-pump or anti-slam scheme. You just wouldn't do it.

Mitsubishi Electric Develops New Gas-insulated Switchgear

Feb 04, 2019. Mitsubishi Electric Corporation has developed two technologies for gas-insulated switchgear. An arc-cooling technology achieves a 25 percent improvement in the interruption of electrical current in sulfur-fluoride (sf 6) gas-insulated switchgear used in high-voltage power systems. Also, a high-density dielectric coating technology improves insulation performance by 30 percent in high-voltage conductors.

gaz sf6 is approximately 100 times more effective than air in quenching spurious arcing. gaz sf6 also has a high thermal heat capacity that can absorb the energy of the arc without much of temperature rise. Electrical properties. The excellent dielectric properties of sf 6 are due to the electronegative character of its molecules. It has a pronounced tendency to capture free electrons forming heavy ions with low mobility making the development of electron avalanches very difficult.
