| Abstract: | The harm and classification of stray current are introduced. The generation mechanism and dynamic characteristics of dynamic direct-current stray current in track traffic are analyzed. Several commonly used measurement methods of stray current, including pipe to soil potential method, soil surface potential gradient method, current probe method and intelligent stray current tester, as well as the judgment criteria are compared. |
