Resumo
As descargas atmosféricas possuem potencial de danos diretos e indiretos muitas vezes irreversíveis, a implantação de um sistema de SPDA (Sistema de Proteção Contra Descargas Atmosféricas) é o principal fator de minimização dos prejuízos causados por essas descargas. O tema proposto por este trabalho tem como objetivo demonstrar de forma sucinta e clara todas as etapas para o desenvolvimento de um projeto de sistema de proteção contra descarga atmosférica respeitando a NBR-5.419/2015. As principais etapas de um projeto de SPDA foram levantadas através de análise da própria NBR e de artigos selecionados através de critérios como tempo de publicação e origem, tais etapas para desenvolvimento do SPDA são: análise de risco, classificação, métodos de captação e posicionamento de descidas e aterramento. Ao final demonstra-se a aplicabilidade dos conceitos em um estudo de caso que engloba os principais pontos em questão, além disso, foi realizada uma análise técnica sobre o tema. Concluiu-se que as etapas propostas como metodologia de desenvolvimento para SPDA atendem a necessidade de proteção de indivíduos e equipamentos.
Atmospheric discharges have the potential for direct and indirect damage, which are often irreversible, the implementation of a LPS (Light Protection System) is the main factor for minimizing the damage caused by these discharges. The proposal of this work has as purpose to demonstrate in a succinct and clear way all the steps for the development of a project of protection system against lightning, respecting the NBR-5.419/2015. The main steps of a LPS project were raised through the analysis of the NBR itself and articles selected through criteria such as publication time and origin, such steps for the development of the LPS are: risk analysis, classification, methods of capture and positioning of descents and grounding. At the end, the applicability of the concepts is demonstrated in a case study that encompasses the main points in question, in addition, a technical analysis on the subject was carried out. It was concluded that the proposed steps It was concluded that the steps proposed as a development methodology for meet the need to protect individuals and equipments
