Sažetak
An electromagnetic model of the non-equipotential large earthing system at power frequency includes transversal and longitudinal mutual impedances between segments of earthing conductors. This paper describes a new algorithm for computing the mutual impedances. Because the integrand contains a singularity and involves a double integration, the integral expressions for mutual impedances are subdivided into two terms. The first term can be computed as the solution of an analytic expression. The second term is not singular and can be evaluated by a new numerical integration routine, which is based on seven-point numerical integration with Gauss-Legandre quadrature.
