Abstract:

There are numerous transmission and distribution problems encountered in the development and operation of electrical power systems. A number of interference and protection problems arise due to unavoidable interaction of such systems with nature and each other. These interactions arise because the earth is involved as a return conductor for both types of systems, either during normal or abnormal operation typified by system faults. It is essential to determine the soil resistivity and maximum grid current to design a substation grounding system. This work provides the soil resistivity values with the type of soil at various locations, which serve as the best reference point for safe grounding system for electrical power substations, communication base substations and transmitter tower antennas.

Keywords:
