System Grounding Opname in the Faculty of Science Laboratory Building

Abstract

This research aims to find out whether the grounding system has been installed properly in the Laboratory Building of the Faculty of Social Sciences, Padang State University. The feasibility of grounding can be seen from the results of measurements using an Earth Tester. This is intended to see how the grounding system is installed in the social sciences faculty laboratory building. After that, measurements of the grounding values installed in all laboratory buildings of the social sciences faculty will also be carried out. A good grounding value should be between 0 and 5 Ω. In this study, the grounding value was measured using the HIOKI FT6031 Earth Tester measuring instrument with a three-point measurement method. This measurement is used to see whether the grounding system installed in the social sciences laboratory building complies with PUIL or not. The results of this research carried out in the final period of 2023 from the measurement results can be concluded that the value measured directly from the grounding system carried out in the Laboratory Building of the Faculty of Social Sciences, Padang State University is > 2000Ω which does not match the PUIL value in 2011. This is because the grounding system has not yet been installed properly and correctly in accordance with the provisions of PUIL 2000. As the measurements carried out, especially by the laboratory of the faculty of social sciences, at the beginning of 2024, they have installed grounding with quite good results below 5 ohms.
