In the process of distributing electrical energy there are often disturbances caused by internal disturbances and external disturbances. External disturbances that often occur are lightning strikes. This disturbance can cause overvoltage, to anticipate the risk of transformer damage caused by grounding system failure. So a good grounding system is created. In electric power systems, grounding resistance must be as small as possible. The amount of grounding resistance must be lower than 5 . This research aims to produce a grounding system with variations in the configuration and depth of the ground electrode and determine the effect of the configuration and depth of the ground electrode on the ground resistance value. To obtain grounding calculation results that are small than 5 , electrode configurations with 1, 2, 3 and several rod electrodes are used. The results of calculating ground resistance using 1 rod electrode with a depth of 0.5 m is 29,36 , a depth of 0.75 m is 29,11  and a depth of 1 m is 28,91 . Using 2 rod electrodes, a depth of 0.5 m is 16,79 , a depth of 0.75 m is 16,65  and a depth of 1 m is 16,53 . Using 3 rod electrodes, a depth of 0.5 m is 12,59 , a depth of 0.75 m is 12,48  and a depth of 1 m is 12,40 . And the calculation continues until using 12 rod electrodes with a depth of 0.5 m of 4,34 , a depth of 0.75 m of 4.30  and a depth of 1 m of 4.27 . Based on the calculation results, conclusions are drawn from several rod electrode configurations that have been calculated. The rectangular configuration model has the smallest grounding resistance value. The value of grounding resistance with a configuration of one rod electrode, two parallel rod electrodes, three triangular rod electrodes and a rectangular rod electrode configuration will be smaller if the electrode is planted deeper below the ground surface.
