Calculation of grounding system by finite element method

Abstract

A numerical calculation of the three-dimensional current field of a ground electrode in inhomogeneous soil is given. The finite element method based on the variational principle is used. The space elements created by dividing the cylindrical coordinate system by an isoparametric coordinate transformation are mapped into a rectangular coordinate system. From the given potential of the ground electrode, the potential at selected points in space is calculated, and then the current that the ground electrode takes from the network.
