Earthing system aims to secure the electrical equipment and is located in the vicinity of human disturbance by flowing fault current to ground. One of the factors to get a little grounding resistance value is the location of the electrodes that will be planted to know the value of earthing is required measurements. One of the elements that need to be considered in the measurement of a grounding system is the condition of the soil in the area where the grounding system will dipasang. Pengukuran performed using 6 (six) 6 different points, with a soil depth of 6 meters. This measurement aims to determine the grounding resistance on the ground. In general, the equipment at the substation earthing parent aims to maintain the safety of equipment and personnel in it, both in normal times and in times of disruption. Equipment grounding system rod and the lattice (grid) is used to limit the voltage arising on the equipment and leveling the ground surface tension gradient. From the analysis we concluded that the earthing system is used both for neutral grounding of an electric power system, earthing and lightning protection system grounding for an equipment especially in the field of telecommunications and electronics needs serious attention, because the earth is a basic principle that is used to a protection system.Keywords : Earthing System, Substation, Grounding Roll.
