This paper has proposed a methodology to obtain a frequency dependent distributed‐parameter model for a buried bare conductor employing a time‐domain fitting from measured transient voltages and injected currents. The transient characteristic impedance and propagation function are expressed by a rational function in a z‐plane and a genetic algorithm (GA) has been used as an optimization tool. Frequency dependence of the per unit line parameters ( RLGC ) is derived from the obtained propagation parameters. Simulation results by the proposed model agree well with that from the measured results. © 2006 Institute of Electrical Engineers of Japan. Published by John Wiley & Sons, Inc.
