Lasit fáddágilkoriid | Čoahkkáigeassu: | In order to protect installations, electronic equipment, housings, metallic structures, etc., grounding systems are essential. Also, they ensure the safety of people by providing a specific path for fault currents to be discharged towards the grounding grid or electrode. Based on the standards IEEE Standards 80 edition 2013 and NFPA 780 edition 2014, the following work develops a methodology for designing grounding systems in electrical systems where there is a transition point from medium voltage to low voltage, and protection systems against atmospheric electrical discharges for ordinary structures. Also, a guide was elaborated where the process to follow to dimension the protection systems mentioned above is detailed step by step. Soil resistivity is an important factor to consider; therefore, a soil study was carried out using the Wenner method, which employs 4 equidistant picks. In the same vein, the established criteria and methodologies were applied to the development and installation of a grounding system for the 75 kVA transformation center feeding block A3 of the Faculty of Energy, Industries and Non-Renewable Natural Resources, which consists of a rectangular mesh with nine electrodes of 1.8 meters and a system of protection against atmospheric electrical discharges consisting of a triangular mesh with three electrodes of 1.8 meters and an active lightning rod model FM-ESE 15. As a result, it is important to comply with the standards for safety (touch and step voltages) established by IEEE Std 80, as in all cases a very low grounding resistance cannot be achieved Keywords: Lightning protection, ground resistivity, grounding systems. |
