2012/2/14At first thinking, it seems possible to open the breaker with very low or zero SF6 pressure, after it is completely isolated from the line and busbar sides, and grounding also provided at both ends (remote end breaker would be opened first). It is because after isolation, there would be no need of insulation and arc quenching, provided by SF6.
