Risk Analysis of Lightning Protection System for Buildings

Lightning strike is a very destructive and unavoidable phenomenon that can cause significant damage to the structures and destroys any object which comes in to its radar. Lightning risk assessment includes the study of actual measures that are the real reasons for the risk caused by the lightning strike. It evaluates the hazard and risks of lightning strikes to people, structure and systems. Risk assessment determines the need of lightning protection system and mitigation measures. Risk Assessment for lightning protection system is done by using EN 62305-2 standard by considering IEC standards as a reference. The dimensions of the building are put into the risk assessment software to analyse level of protection. The purpose of this is study is to consider a building and to do a proper risk assessment through software and to propose a lightning protection system for overall protection of the building. Internal protection of the electronic equipment from indirect effects of lightning strikes by using Surge protection devices (SPDs) is also crucial as it helps to protect the electronic devices from damaging effects of indirect lightning strikes.
