Sf6 purity analyzers in switchgears - Switchgear Content

May 20, 2020 · insulating gas purity is typically measured using conductivity or speed of sound measurement techniques. Impurities that reduce the percentage of Sulfr hexafluoride 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.Get price
