Transmission Tower Grounding Design with Horizontal 2-Layer Soil Model

Grounding resistance is the basic performance indicator of grounding electrodes and the resistance has been calculated by simple equations, which is based on the assumption of uniform soil model. In this paper, tower grounding resistance is calculated assuming horizontally 2 layered soil model using finite element analysis method. A simple grouding design graph has been resulted from the calculation results.
