  • Electron capture detector(ECD) method for sf6 gas switchgear

    Aug 30, 2019 · An electron capture detector (ECD) is used to detect SF6 with high sensitivity below 1 ppmv. This device makes use of the high electron attachment coefficient of SF6, i.e. the ability to capture electrons. The free electrons to be attached to the SF6 molecules are created by a radioactive source. The ECD uses a radioactive emitter, typically, a metallic membrane coated with the radionuclide nickel.

  • Study on field demonstration of high‐sensitivity SF6 leakage

    SF6 gas is widely used in power equipment such as gas insulated switchgear or gas circuit breaker. However, its global warming potential is 23,500 times higher than that of CO 2. In consideration of environmental protection, detection of SF6 gas leakage with high sensitivity is necessary. The authors proposed an algorithm to accurately estimate the average gas temperature from the tank surface temperature for establishing a high‐sensitive SF6 slow leak detection technology.
