M. Adesina1,* and T. O. Akinbulire2 1, ENGINEERING & STANDARDIZATION, EKO ELECTRICITY DISTRIBUTION CO., LAGOS, LAGOS STATE, NIGERIA. 2, DEPT. OF ELECTRICAL & ELECTRONIC ENGINEERING, UNIVERSITY OF LAGOS, AKOKA, LAGOS STATE, NIGERIA E-mail addresses: 1 [email protected], 2 [email protected] ABSTRACT Engineers and planners have realized that equipment grounding is a necessary part of installation process in Electrical power substations. Over years, grounding or earthing has been carried out primarily through preparation of Earth Mat which is interconnected with several Earth-rods buried around the equipment under consideration. This approach takes several efforts to have an acceptable and reliable result. However, this paper presents a more flexible, economical and results oriented approach. A flow chart which describes the procedures of carrying out the proposed method of earthing is developed. This was applied to two case studies: a proposed Power transformer substation and distribution Transformer substation located within the same geographical domain. On the two cases, the measured earth resistances are presented and discussed. The results from the case study indicates that the earth resistance values obtained from this new approach are reliable and in compliance with IEEE Standards 80,142, 81 and 1100. Keywords: Equipment, Grounding, Earthing, Earth-rod, Flowchart, Earth Mat, Flow Process, Injection Substation, Distribution Substation, Earth Resistance, IEEE Standard.

  • Earthing and Protection
    Earthing and EARTHING AND PROTECTION System Protection While the use of electricity is a boon to us, its misuse, any fault in the system can be a curse, indeed, it could lead to complete damage of the equipment and subsequently can damage the entire system and can also cause major accidents, including fatal ones. Hence, we have to cautions. In practical sense, we need to provide for safe use of electricity. As we shall learn, earthing is the most important factor in this regard. Of course, earthing may also serve other purposes in the electrical system. Protection of the electrical equipment and the network is another safety measure, as it helps save not only our investment in the electrical system, but also, it may help prevent accidents related to electricity. You shall be introduced to ‘Earthing and System Protection’ in this second part (Block 2) of this Course 1 : Electricity and Safety Measures as most useful and necessary and critical component of power system. The first part introduces you to electrical Earthing. In this part, you will be acquainted with importance of earthing, earthing classification, line and pole earthing, measurement of earth resistance. It also touches upon the treatment for minimizing the earth resistance values, maintenance of earthing system, definitions of general earthing terms. Thereafter, in the second part you will be introduced to the Electrical System Protection. In this part, you will learn about the objectives of protection, equipment for system protection, protective relays, functional requirements of relays, distribution system protection, substation protection where you will be introduced to principle of differential relay operation, transformer protection, bus protection.
