“…It is worth noting that formulas (19) and (25) can only deal with conductors carrying AC currents with opposite polarity, whereas FEM simulations can deal with both, currents of the same and opposite polarity. This section compares the results for two parallel conductors carrying opposite AC currents provided by the approximated formulas (19) and (25) with those outputted by the FEM model and experimental measurements from [18]. Table 5 summarizes the results of such formulas for two AWG-0000 parallel solid round conductors with diameter 11.68 mm diameter carrying currents of opposite polarity.…”

Abstract-Skin and proximity effects in single-or multi-conductor systems can notoriously affect the AC resistance in conductors intended for electrical power transmission and distribution systems and for electronic devices. This increase of the AC resistance raises power loss and limits the conductors' currentcarrying capacity, being an important design parameter. There are some internationally recognized exact and approximated formulas to calculate the AC resistance of conductors, whose accuracy and applicability is evaluated in this paper. However, since these formulas can be applied under a wide range of configurations and operating conditions, it is necessary to evaluate the applicability of these models. This is done by comparing the results that they provide with experimental data and finite element method (FEM) simulation results. The results provided show that FEM results are very accurate and more general than those provided by the formulas, since FEM models can be applied to a wide range of conductors' configurations and electrical frequencies.
