Abstract

The design of safe grounding systems requires computing the potential level distribution on the earth surface for reasons of human security, as well as the equivalent resistance of the earthing installation for reasons of equipment protection (Sverak et o/.[l], ANSI/IEEE[2]). In the last three decades several methods for grounding analysis have been proposed, most of them based on practice and intuitive ideas. Al- though these techniques represented an important improvement in this area, some problems such as large computational requirements, unrealistic results when segmentation of conductors
