Abstract
Brazil is a country with high incidences of atmospheric discharges and during the year, several people are killed by these discharges. The main known discharge protection measure is the SPDA (Atmospheric Discharge Protection System). In this sense, this work proposes to present the measurements of SPDA (System of Protection Against Atmospheric Discharges) in a school located in the city of Manaus and its role for local security, by measuring the variables of an SPDA system, demonstration of the technical conditions of the SPDA and arguments that point out the relevance of the correct procedure for the realization of this process and importance of spda. For this, bibliographic research and on-site field study of the entire spda installation process was carried out in the buildings, multi-sport court and school water box. According to the studies conducted, it was observed that as measurements of ohmic resistances measured were low, very close to 0 ohms. The stress measures were collected, which were also low. The INSTALLED SPDA went to the Cage of Faraday and Franklin. For the school under study, the implanted SPDA obeyed all the standards that regulate it. The college is an environment frequented by many people of different age groups, the installation of spda implanted and sized ensures the protection of heritage, as well as safety and protection to life, because in case of an atmospheric discharge, there is a system who will receive it and lead it there is a path designed for it. If there were no, the building would be fully exposed to this risk and so would people. Therefore, even if spda does not guarantee absolute protection, the protection range it meets is representative, thus ensuring in a certain way the safety of people and protection of building and people. It was also found that the maintenance of the SPDA should be done annually from the start date of the technical report, to ensure the effectiveness of the system.
