Assessment of Lightning Protection System in University Campus

Abstract

Lightning is a natural phenomenon that typically results in significant physical damage in areas where it strikes. Extensive research has been conducted to mitigate the effects of this damage, leading to the identification of specific precautions and practices. By adhering to both Turkish and international standards, an optimal lightning protection system can be established by integrating various components. The lightning protection system comprises an internal lightning (lightning rod) installed within the building, an external lightning system chosen based on the building's structure, and a robust grounding system. These components must adhere to established standards and techniques to ensure their effectiveness. In this paper, the protection of structures from lightning, analysis of the existing systems, the determination of the problems and the evaluation of the solution proposals have been carried out in order to reduce the loss of life, property and service that may ocur in terms of Occupational Health and Safety in and around the Balkan Campus of Trakya University. By making the width-length-height measurements of the buildings located in the campus, the lightning risk calculations of the buildings, the lightning protection radius calculations of the existing protection systems and the determination of the grounding resistances have been made. As a result, it was determined that 17 of the 29 detected lightning rods were inappropriate and maintenance-repair-replacement activities should be carried out immediately. Additionally, it has been calculated that the lightning protection radius is insufficient.
