  • SF6 gas as insulating and arc-quenching medium

    Sep 20, 2011Arcing causes the decomposition of very small amounts of SF6 gas. The decomposition products react with water, therefore the gas’s moisture content, particularly in the circuit-breaker, is controlled by drying (molecular) filters. Careful evacuation before first gas filling greatly reduces the initial moisture content.
