Estudo de perdas de potência em condutores rígidos em circuitos baixa tensão

Abstract

The present work is based on studying electrical circuits that are outside the installation standards, whether by undersized conductors, old conductors and others, in addition to comparing these data with the circuit corrected according to the standards. More economical, adequate and viable ways to consume electricity are continually sought, including compliance with standards, because the more savings and safety, the better for the consumer and the supplier. The research starts from a theoretical referential study, followed by a case study with a survey of existing residential installations that present possible non-conformities with the regulations in force and energy losses. The field experiment includes surveying and measuring the conditions of electrical quantities, which allow the analysis, proposal and implementation of improvements, with a new measurement for effective verification of post-intervention feasibility. The analysis includes the development of a procedural model, in order to allow a degree of generalization of the applied solution. In the execution of the measurements, non-conformities were found in what refers to the absence of protection circuit breakers for over voltage and incompatible wiring. It was observed that the greater the overload on the conductor, the more it will negatively influence the performance of the installation in which it operates, being necessary to change it, avoiding unnecessary and dangerous consumption of energy.
