  • A highly accurate algorithm for SF6 leakage detection

    Sulfur hexafluoride (SF 6) is widely used in high‐voltage applications such as gas‐insulated switchgear (GIS) because of its excellent arc‐quenching properties.The main drawback of SF 6 is that it is a strong greenhouse gas. Detecting small SF 6 leakages in GIS is very important to protect the environment and to prevent the failure of aged GIS. To detect SF 6 leakage…Cited by: 1
