In this paper the influence of earth's conductivity and permittivity frequency dependence are evaluated when calculating transversal and longitudinal transmission lines' parameters. The aim is to compare results calculated from the complex plane method and Carson's modified expressions on longitudinal parameters and also between Carson's modified potential-coefficient correction factors and results from approximations methods for transversal admittance parameters. The importance of properly considering the frequency-dependent soil model is presented for oneconductor case, in order to compare the longitudinal and transversal parameters considering the earth's conductivity and permittivity frequency dependence soil model in relation to the common soil representation with a constant conductivity and a permittivity that can be neglected assuming a low frequency approximation.225506522Arismunandar, A., Capacitive correction factors for transmission lines to include finite conductivity and dielectric of the earth (1963) Proceedings of the AIEE Summer General Meeting and Nuclear Radiation Effects Conference, pp. 436-455. , Toronto, Ont., Canadá, June 16-21, 1963Carson, J.R., Wave propagation in overhead wires (1926) Bell System Technical Journal, 5, p. 539554. , 1926Deri, A., Tevan, G., Semlyen, A., Castanheira, A., The complex ground return plane, a simplified model for homogeneous and multi-layer earth return (1981) IEEE Trans.
