This research is entitled analysis of the grounding system for the transmission 150 kV Kasongan ? Kuala Kurun high-voltage tower grounding system. If the tower leg resistance is still more than (?) 10 ?, the counterpoise method is added so that the tower leg resistance is less than ?10 ? according to SPLN T5.012:2020 and SPLN T6.003-2021. This research method uses a quantitative, transmission 150 kV Kasongan ? Kuala Kurun which are located in different locations, namely forests, roads, rice fields, rubber plantations, rivers. The resistance value of the soil type at the foot of the tower is 1 ?-m to 1260.47 ?-m, including swamp soil, clay soil, salt-containing soil, wet sandy soil and boulders. in the drived rod grounding system, a total of 59 towers was added, then the counterpoise method added 22 towers because the results of the grounding of the tower legs were more than (?) 10 ? after repeated measurements, the grounding value of the tower legs became less than (?) 10 ?. With the drive rod system, the grounding value of the tower legs is almost the same, whereas with the addition of the counterpoise system method on the tower legs, the results of the grounding of the tower legs differ by about 6?.} }
