  • gaz sf6 circuit breaker maintenance - Siemens USA

    The first generation of sf6 gas circuit breakers was the lower voltage classes of 72kV and 145kV. As Sulfr hexafluoride breaker technology improved, circuit breaker manufacturers introduced a dual pressure design for 145kV through 800kV applications, as well as air-blast breakers utilizing Sulfr hexafluoride as the line-to ground dielectric insulation.

    SF 6 is recognized as an extremely potent greenhouse gas, primarily because of its atmospheric lifetime of about 3,200 years, with a global warming potential (GWP) of 22,800 years. The reference gas for GWP values is CO 2, which is assigned a GWP of 1.0. The EPA considers SF 6 as the most potent greenhouse gas that they have investigated. 1

  • The Problem with Humidity in sf6 gas Gas-Insulated Systems

    Humidity in SF 6 Gas The SF 6 in the gas compartment can absorb a certain amount of water. When the amount of water exceeds the saturation point of the gas, the excess condensates and forms a water layer (if the gas temperature is above freezing) or sublimates and forms an ice layer (if the gas temperature is below freezing).
