In this paper, the three-dimensional finite element model of a low voltage and heavy current three-phase busbar bridge system is established. The edge element is used to discretize the finite element equations of the electromagnetic field. The main characteristics of magnetic flux density and electromagnetic force in the system are obtained. Through the comparison between calculation results and measured ones, the reliability of the calculation is validated. The influence of the operating current, different arrangements of three-phase busbars, space between each phase busbar and frequency on electro-magnetic parameters, especially magnetic flux density and electromagnetic force, are also studied.
