Abstract :
This paper presents frequency-dependent series impedance models of three phase overhead transmission lines, taking into account the influence of bundled conductors using, the skin effect of the conductor, ground-return path with earth resistivity which is as a frequency-dependent complex function. Analysis results are included.
