Abstract :
This paper presents a new model to represent multiphase 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 model is described for three-phase lines. The exact eigenvector of the non-transposed line is analyzed in the frequency domain for some earth resistivity and compared to Clarke components
