The aim of this paper is the development of a theoretical and experimental study on the characterization of MV cables in the frequency range 25-200 kHz. Two transmission line configurations, line-ground and line-line were considered in order to evaluate the main parameters, as the characteristic impedance and the attenuation constant a. A simplified model of the line-ground configuration is proposed which allows one to evaluate the characteristic impedance and the attenuation constant by means of the geometrical dimensions. The model was verified by experimental measurements on commonly used MV cables, RG7H1R, with an aluminum core of different sections, 95 mm2 and 185 mm2. Moreover, the experimental tests were carried out for the line-line configuration.
