dc.description.abstractEquipment grounding is a necessary and conclusive part of an installation process in electrical power system networks particularly in power substations. Over years, grounding or earthing of substations has been carried out primarily through the preparation of an earth mat which is simply interconnected with several Earth rods buried around the substation or any other equipment under installation. Apart from the fact that this approach is old, it is in addition requires several efforts to have acceptable and reliable results. Thus, a more sophisticated, reliable, and results-oriented is required to be in place. This paper presents a modern approach to earthing of transformer substations and other allied equipment. The approach negates the constraints that are obtained in the old approach. A 15MVA, 33/11kV power transformer substation as well as a 500kVA, 11/0.415kV distribution transformer substation’s installations were selected as the case study. A flow chart that describes the procedures of carrying out the proposed modern method of earthing is developed and applied to the two case studies. The various earth resistances measured in both cases are presented and discussed. The results from the case study indicate that the earth resistance values obtained from this new approach are reliable and in compliance with IEEE Standards 80,142, 81, and 1100.
