In order to improve the precision of electrical grounding system simulations, we have developed a new application based on the 1D Galerkin boundary element method using linear basis functions. The calculations described here can be used to simulate and analyze complex structures located anywhere within a multi‐layer earth model. We introduce a quasi‐static complex image method implemented by the matrix pencil approach, which results in a closed‐form for Green's function. The resulting application is very efficient, requiring only a few minutes on a Pentium 4 computer to simulate realistic systems. Copyright © 2009 John Wiley & Sons, Ltd.
