Assessment of electromagnetic forces resulting from arbitrary geometrical busbar configurations

Abstract

Computation of forces to which busbars are subjected, both in normal and transient situations, have always been an important issue in order to provide sufficient clamping mechanisms and/or suggest suitable inter-busbar spacing criteria. This paper presents an analytical approach using which forces and force densities acting on busbars may be computed. Details of the approach and sample numerical simulations are given in the paper.
