Abstract :
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.
