Análise das instalações elétricas de uma casa de farinha em Santana de Piauí e adequação à NBR 5410:2004.

Abstract

Electrical installations are nothing more than the infrastructure responsible for allowing electrical equipment to receive electrical energy from utilities or other sources of energy so that they can perform the functions for which they were designed. For the electrical equipment to function properly, it is necessary that the electrical installations are correctly sized, otherwise, the operation of this equipment will be compromised and not only that, the entire electrical installation itself may represent a risk to people's lives. In order for low voltage electrical installations to be dimensioned and properly executed, the Brazilian Regulatory Standard 5410 of 2004 (NBR 5410: 2004) establishes the requirements that these installations must meet. However, the majority of low voltage electrical installations in Brazil do not comply with NBR 5410: 2004. In this sense, the present work analyzed the state of the electrical installations of a flour mill in Santana do Piauí/PI, verifying the main points of non-conformities with NBR 5410: 2004. In addition, an electrical project was prepared as a proposal to adapt to the nonconformities found and their respective budget. The analysis of the electrical installations under study was made based on a survey of information “in loco”. It was found that the electrical installation presents several points of non-conformities such as NBR 5410: 2004, such as: the correct dimensioning of the protection devices, the division of the circuits and the section of the conductors. The results obtained show that the electrical installation in question needs numerous corrections. They also show that the project prepared by a qualified professional avoids numerous inconveniences to the building owners.
