    Abstract: Overhead transmission lines often trip due to the excessive growth of trees, which affects the power supply stability of the transmission lines. The ultra-high growth of trees in overhead transmission lines lead to three progressive processes: corona discharge, hazard discharge and flashover discharge. Based on the discharge process during the ultra-high growth of trees, this paper builds an Ansys simulation model to study the clearance distance of the ultra-high discharge process of trees at different voltage levels, meanwhile the tree ultra-high growth experiment is carried out, then the traveling wave data of tree discharge characteristics are analyzed during the experiment, thus obtaining traveling wave characteristics at different clearance distances to formulate the tree ultra-high growth early warning method, which provided a scientific and reasonable early warning method for hidden discharge of overhead lines and ensured the stability of power supply of overhead transmission lines.
    Key words: overhead transmission line; Ansys simulation; tree discharge; traveling wave
