  • Health and environmental dangers of SF6-filled switchgear

    SF6 gas, used as a dielectric medium in circuit breakers and switchgear, has a global warming potential 24 000 times greater than CO2 and some of its by-products were used as chemical weapons in World War I. In life, in business, in the ordinary course of doing things, there is a certain level of risk that comes with just existing.

  • Three abnormal situations leading to an uncontrolled release

    Jun 18, 2019 · This applies to any type of switchgear, SF6 filled or otherwise. If, for example during a busbar fault, only 10 grammes of copper were evapourated into the example medium voltage switchroom atmosphere, the concentration (neglecting the effects of oxidation) would be (mass of Cu / room volume) = 83 mg/m 3. The TLV for copper vapour is 0.2 mg/m 3.

  • SF6 Gas Analysis - Qrometric

    For SF6 filled gas compartments, SF6 in accordance with either IEC 60376 or IEC 60480 is used. In order to prevent condensation, the maximum allowable water content is defined by a dew-point no higher than – 5 °C. Gas compartment fill specifications typically define much lower dew points (manufacturer dependent).
