Abstract

The purpose of this paper is to investigate the ionization and dispersion effects in combination with the inhomogeneity of soil simultaneously on the effective lengths of counterpoise wires.Design/methodology/approachImproved multi-conductor transmission line model is used for computing effective length of counterpoise wires considering all aspects of soils.FindingsThe simulation results show that the ionization and dispersion effects simultaneously results in placing the effective length between situations where only one effect is considered. Also, predicting formulae for effective length of counterpoise wires considering all effects are proposed.Originality/valueA sensitivity analysis on the effective lengths of counterpoise wires considering all aspects of soils is carried out.
