DESENVOLVIMENTO DE UM SOFTWARE COM INTERFACE GRÁFICA PARA AUXÍLIO EM DIMENSIONAMENTOS DE CIRCUITOS DE BAIXA TENSÃO CONFORME NBR 5410:2008

Abstract

Electrical installations are closely linked to civil construction, an area that has developed significantly in Brazil, contributing to the generation of income and employment. One of the main elements of an electrical installation are the conductors, which must be correctly sized according to current standards, such as ABNT NBR 5410 and ABNT NBR 11301, thus avoiding accidents due to incorrect sizing. Software is commonly used to assist in the electrical sizing stage, bringing agility and reliability to the project to be executed. In this sense, this work proposes the development of software capable of sizing low voltage (LV) electrical cables in accordance with NBR 5410 and NBR 11301, named DCBT (Dimensionador de cabos de baixa tensão). DCBT is built with Electron JS, an open-source web-based framework used for the development of computer applications. The software developed has a graphical interface and is capable of generating dimensioning reports, displaying the equations and tables relevant to the calculation. It is also capable of saving the dimensioned circuits for later consultation, separating them by project created within the tool. At the end of this work, DCBT proved to be a tool capable of dimensioning cables accurately and with values consistent with those obtained when dimensioning is performed manually.
