  • SF6 Gas Measurement Theory - MBW Calibration AG

    Daniel Mutter, MBW Calibration, Wettingen, Switzerland Sulphur hexafluoride, SF 6 , is a non-toxic, inert, insulating and cooling gas of high dielectric strength and thermal stability. Due to its high dielectric strength, it is particularly suited for application in high power circuit breakers as well as in high-voltage cables, transformers, and switchgears.

  • Sf6 purity analyzers in switchgears - Switchgear Content

    May 20, 2020 · SF6 purity is typically measured using conductivity or speed of sound measurement techniques. Impurities 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.

    IntroductionHistorySolution and SuccessApplicationsHow The Veu TravelsDetermining the location of a leak in an underground gas line has long posed difficult problems for gas line repair crews. Although the gas line itself is easily located, the soil is often saturated, which makes it difficult to pinpoint the actual location of the leak. As a result, it has not been uncommon for large stretches of a surface, including paved roadways, to be excavated in a somewhat random fashion. This, of course, is costly and time-consuming. In addition, the continuous leaking gas creates a greater hazard the longer the leak continues.

    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).
