Electric Field Analysis and Design of Direct current Arresters for electric Traction Vehicles

This paper describes electric field analysis and design of direct current arresters for electric traction vehicles. Generally, DC arresters are used to protect the electric traction to limit the overvoltage invading into its inner electrical circuits. We could proposed operating voltage(Uc), the rated voltage(Ur). Finally maxwell 2D simulator based on the boundary element method was also introduced in order to verify the reliability of the DC arresters.
