  • Sf6 purity analyzers in switchgears - Switchgear Content

    May 20, 2020Impurities that reduce the percentage of SF6 by volume are mainly handling the gas, the filling and emptying of compartments that may inadvertently incorporate air and water vapor due to erroneous operation, incomplete evacuation of pipes and vessels, leaks in connections, and seal surfaces. Systems are often used in field density meters.

  • Myth About SF6 Gas In Electrical Equipment

    May 25, 2020Pure SF6 is physiologically completely harmless for humans and animals. It’s even used in medical diagnostic. Due to its weight it might displace the oxygen in the air, if large quantities are concentrating in deeper and non ventilated places. Legislation for chemicals does not categorise SF6 as a hazardous material.

  • 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.
