There have been ways since time immemorial to minimize or mitigate excessive hazardous voltages in the case of lightning surges or system faults due to some rise in ground potential. Grounding Electrodes plays an important part in energy systems. It contributes to energy transmission and distribution. In this case I am going to model a grounding electrode using COMSOL Multiphysics in order to compare the resistance of the soil and solve using different analytical equations to determine ways to improve the model when applied. It is important to note that as the energy system in Zimbabwe improves, there has been growing need to improve its underground protection from lightning.Because of Zimbabwe’s soil, climate and power infrastructure requirements, underground (earthing/grounding) electrodes are both technically and safety-critically important. This study will focus on grounding electrodes, the modelling using COMSOL and how to improve the underground electrodes for the safety of high voltage equipment such as transformers in relation to the types of local soils.
