Most high voltage breakers already are SF6. They rely on the 0-point crossing to quench the arc.

- Faaak 3y agoBut is there not 0-point crossing in DC currents ?
- eternityforest 3y agoThe current is always positive except when it's turned off. It never reversed so it never passes through 0v to get to negative volts. Which is also the big advantage, since you're not spending part of the time at lower voltage.
