Abstract:

Under normal conditions, electrical power systems will satisfactorily deliver power with the need of proper grounding. Grounding is very important for the generation, transmission and distribution systems of electrical power. Grounding creates stability for the electrical networks; the neutral grounding is useful in discharging over-voltages due to lightning to the earth, grounding is used in simplified design of earth fault protection, the grounded systems require relatively lower insulation levels as compared with underground and finally the most important reason is to protect people. Grounding system may be steel, copper or other materials, these materials prone to corrode. This study is specifically concerned with the effect of corrosion on steel grounding grid and methods to compensate the gird and surrounding metallic rods which are subjected to corrosion. Also this paper introduces the design of a cathodic protection of electrical substation grounding system in which a steel ground grid and rods are used instead of copper.
