Analisis Sistem Pentanahan Transformator Distribusi 20 Kv Di Tvri Kota Pekanbaru
ABSTRAK
The grounding system is an important part of the electricity distribution network that functions to protect equipment and humans from electrical disturbances due to insulation failure or overvoltage. Good grounding allows the fault current to be channeled to the ground efficiently, thereby reducing the risk of electrical accidents and equipment damage. The grounding resistance value is influenced by various factors, such as soil type, electrode depth, number of electrodes, and distance between electrodes. The PUIL standard regulates the requirements for electrical installations to ensure the safety and reliability of the electric power system. This study was conducted at TVRI Pekanbaru City to analyze the grounding system on a 20 kV distribution transformer that has been installed since 1999. The research location has soil types in the form of clay and rock sand, which affect the grounding resistance value. Testing was carried out by varying the configuration, depth, and number of electrode rods to evaluate the effectiveness of the existing grounding system. The results of this study are expected to provide recommendations for optimizing the grounding system to improve the safety and performance of electric power distribution at TVRI Pekanbaru. Calculations show that with 4 rod electrodes, the resistance value is 6.43 Ω at a depth of 0.5 m and 6.33 Ω at a depth of 1 m. Meanwhile, with 8 rod electrodes, the resistance value decreases to 3.73 Ω at a depth of 0.5 m and 3.67 Ω at a depth of 1 m.
