dc.description.abstract | This paper analyzes the skin and proximity effects in different conductive nonmagnetic straight conductors’ configurations subjected to applied alternating currents and voltages. These effects have important consequences, including a rise of the ac resistance, which in turn increases power loss, thus limiting the rating for the conductor. The alternating current (ac) resistance is important in power conductors and bus bars for line frequency applications as well as in smaller conductors for high frequency applications. Despite the importance of this topic, it is usually not analyzed in detail in undergraduate and even in graduate studies. For this purpose, this paper compares the results provided by available exact formulas for simple geometries with those obtained by means of two-dimensional finite element method (FEM) simulations and experimental results. The paper also shows that FEM results are very accurate and more general than those provided by the formulas, since FEM models can be applied in a wide range of electrical frequencies and configurations |
