In electrical engineering, the necessity of grounding system refers to a system where conductor is grounded and intended or may cause the current to flow under normal operations. Grounding system is designed for appropriate of the clearing the grounding faults and dissipates the lightning energy. Most commonly used material for the grounding system is copper. However the increasing price and theft issue of copper has led to research materials other than copper with additive filler to overcome problem as well as maintaining the efficiency of an electrical system. The current project analyses the mixture of copper and graphite along with silica glass and amorphous carbon used as an additive material for the analysis of the system. The analysis was done using COMSOL multi-physics software. The voltage distribution and current density was analysed which showed that graphite rod can be used instead of copper.
