Abstract

This research presents a mathematical model of the electric field of a single-arm pantograph for an electric train.  Which is expressed in the form of a second-order partial differential equation. The simulation applied the 3D finite element method developed so that graphical results analyzed the propagation of the electric field around the pantograph system and the contact strip at a voltage of 25 kV and a frequency of 50 Hz. To simulate the single-arm pantograph structure with one upper arm and two upper arms, we can simulate the contact strip being made of graphite material, and the contact strip being made of brass material. It was found that the pantograph in the form of two upper arms had a better electric field dispersion effect than the pantograph in the form of one upper arm. And graphite contact strips have a better electric field dispersion effect than brass contact strips.
