Abstrakt EN: Impedance of long direct massive conductors carrying time-variablee currents is a complex function of time. Its evolution is affected not only by the skin effect but also by the temperature rise. This paper presents a numerical method that allows one to compute the resistance and internal inductance of a non-ferromagnetic conductor of any cross-section from values of the total Joule losses and magnetic energy whitin the conductor, and also illustrates the theoretical analysis based on the field approach on a typical example and discusses the results.
