Análise das instalações elétricas do bloco b do IFG - Câmpus Aparecida de Goiânia: estudo de caso

Abstract

This research aimed to carry out an analysis of the low-voltage electrical installations of a building, because of the great impact that this subject can cause in terms of electrical functioning and people's safety. The analysis was based on NBR 5410/2004, Regulatory Standard 10, Regulatory Standard 18, NBR ISO/CIE 8995/2013, and on the authors Creder (2016) and Júnior (2013). The case study was carried out at the IFG campus Aparecida de Goiânia. For this purpose, the methodology used was visual inspection, project analysis, and measurements with a digital multimeter, ammeter pliers, and luxmeter, which enabled the elaboration of a checklist with 45 evaluations. Through this list, 36 requirements were found directly aimed at low voltage electrical installations and 9 requirements regarding lighting in work environments. It was possible to conclude that the building is approved in 26 of the evaluated items, that is, more than half, however, some requirements with non-compliance offer a considerable degree of risk for the users of the building, such as lack of an emergency plan involving electricity, absence of the Electrical Installations Handbook and the non-inspection or half-yearly maintenance in the Atmospheric Discharge Protection System.
