A One-Step Finite Element Method for Multiconductor Skin Effect Problems

A one-step procedure is developed to solve the skin effect problem in multiconductor busbars. The procedure differs from previous solutions in that it treats the source (or quasi-static) current density in each conductor as an unknown. It couples the solution of the diffusion equation to Ampere's law, and allows for the finite element solution of skin effect problems to be obtained directly in one step from the currents imposed by the power system in each conductor.
