Field ionization is adopted as a streamer initiation mechanism in highly pressurized CO 2 , using a 3D particle model. The field ionization is implemented into the 3D model through Zener’s model. Streamer evolution is classified into three stages;

SF 6 is a strong electronegative gas and used as insulating material in gas-insulated switchgear (GIS). For the efficient and reliable operation of GIS, it is necessary to investigate non-uniform field breakdown in SF 6 . Generation of free electrons
