    Construction of Lightning Protection Grounding Module for Photovoltaic Substation

    Lightning protection systems (LPS) provide a protective zone to assure against direct strikes to PV systems by utilizing basic principles of air terminals, down conductors, equipotential bonding, separation distances and a low‐impedance grounding electrode system. Investigating damage to fuses and circuit breakers caused by lightning (poor grounding). The collection area for PV plants are large. Grounding systems have to consist of meshes (20m x 20m/ 40m x 40m). Several grounding grid configura-tions are investigated, and the transferred voltages between the dc cables and supporting structures at. Proper grounding is one of the most important safety measures in photovoltaic systems. Single air terminals offer a cone. This guide explains the theoretical principles and practical implementation of measures for equipotential bonding and lightning protection of PV systems in general – and of S:FLEX mounting systems in particular – based on the relevant technical regulations.
