GROUNDING MEASUREMENTS IN RESIDENTIAL ELECTRICAL INSTALLATIONS IN KUPANG CITY
The grounding system is a crucial component of a residential electrical installation, providing protection against the dangers of electric shock and leakage currents. This study aims to determine the grounding resistance value in residential electrical installations and evaluate their compliance with applicable electrical safety standards. The method used in this study was direct measurement using an earth tester at several grounding points in the residential installation. The measurement data were then analyzed based on the General Requirements for Electrical Installations (PUIL) standards. The measurement results showed that the grounding resistance values obtained varied, with 78 points, with values ranging from 0 to 4 ohms below the standard. ≤ 5 ohms at 72 points and resistance values of 5 – 23.8 ohms above the standard at 6 points. influenced by soil conditions, electrode depth, and soil moisture content and The diameter of the installed conductor wire. Good grounding resistance values are obtained in moist soil conditions with standard electrode installation. Based on the analysis, most installations met safety standards, but there were some Points that still have resistance values above the recommended limits require periodic grounding system repairs. This is based on grounding system measurements and evaluations. This, it is hoped that the level of security of residential electrical installations can be increased and be able to Minimize the risk of disruption or accidents due to electrical current. Can be recommended the electricity company and its team of experts will check the grounding installation in residential homes periodically and it is mandatory to plant the ground in the ground uses rod rod (BC) with a diameter of 4 – 6 mm, so it is easier to conduct excess current to the ground if there is a short circuit that comes suddenly from a large power network.
