EVALUASI SISTEM PENTANAHAN INSTALASI LISTRIK RUMAH TINGGAL
Studi Kasus di Kecamatan Gabek Kota Pangkal Pinang
Grounding is a part of the residence electricity installation. The assembling of electricity installation in Indonesia has been adjusted based on General terms Electrical Installation (PUIL 2000) and the other regulations that support it. Grounding system had purpose to safe the equipment or electric installation by
flowing the fault current in to the ground. The appropriate standard grounding for the whole system no more than 5 ohms, and for the areas that has high resistance the grounding might be 10 ohm. The purpose in this research is to find out the resistance grounding value of residences in Gabek subdistrict, Pangkal Pinang town that has marsh land condition. The data collection techniques by observation, documentation and measurement. Measurements using a 62% methode. Sample data that used are housing residents with details, Selindung villages 25 samples and Selindung Baru 5 samples. The results of the measurements, the lowest grounding resistance value is 11 ohm, and the highest was 950 ohms. Based on the analysis of statistical data and using one sample t test, the results of analysis by using t count and t table as well as the 95% significance level, H0 is rejected. So based on the convinction of 95% the resistance grounding value of electrical installation in Gabek subdistrict residential between off 134.0113 and 325.1887 ohms.
