Abstract :
This paper presents a new model to represent three-phase transmission lines in transient studies, including the frequency dependence of longitudinal parameters. The frequency dependence is represented with synthetic circuits, with a cascade of π-circuits for each mode. The transformation matrix used for the entire frequency range is the Clarke one. The exact eigenvectors of the nontransposed line are analyzed in the frequency domain for some earth resistivity and compared to Clarke components
