Abstract

This paper presents a systematic investigation of equivalent homogeneous earth method (EHEM) for calculation of earth-return impedance of overhead conductors above a multi-layer earth. The recently developed EHEM is based on the concept of equivalent propagation constant of earth. The characteristics of equivalent propagation constant of earth and integrand convergences of EHEM are further studied. The parametric studies of accuracy on earth-return impedance between exact formula (EF) and EHEM are also presented in this paper.
