PERUBAHAN KONFIGURASI ELEKTRODE PENTANAHAN BATANG TUNGGAL UNTUK MEREDUKSI TAHANAN PENTANAHAN

Earthing system needs to be done,it aims to prevent the touch voltage, step voltage and the voltage move that andangers human and equipment failures due isolation. It required a low grounding resistance value or close to zero. Efforts was the instalation of the grounding electrode vertically on the soil clay and sand. The main goal is to get the system grounding resistance value is low, so that the fault current is uniformly distributed immediately inti the ground. Decrease in resistance grounding with grounding electrode implantation deepens. Result obtained with a dept of one meter horizontally 59.59 Ω on clay and sand beach at 28.45Ω, vertically 28.46 Ω at 7.26 Ω clay and sand in the soil.
