Análise do SPDA de uma indústria à luz da NBR 5419/2015 – Estudo de caso

Abstract

Lightning strikes pose a significant risk to industrial buildings, potentially causing structural damage, failures in electrical and electronic systems, and endangering human safety. In this context, the adoption of effective protection systems based on technical standards is essential. This study aims to analyze the Lightning Protection System (LPS) of an industrial facility located in the city of Itumbiara, Goiás, Brazil, according to the criteria established by ABNT NBR 5419:2015. The methodology includes the assessment of the building’s characteristics, analysis of the regional lightning density, calculation of associated risks, and verification of compliance of the existing system. Based on the results, nonconformities were identified and technical improvements were proposed to reduce risks to acceptable levels. The study concludes that the proper application of the risk management methodology defined by the standard is fundamental to ensure building safety, equipment protection, and human life preservation, highlighting the important role of electrical engineers in the design and evaluation of lightning protection systems.
