Análise técnico-econômica da substituição de transformadores trifásicos de distribuição considerando uma amostra padrão no Rio Grande do Sul

Abstract

Transformers are essential equipment for the electrical system, as they are responsible for increasing or decreasing the voltage of electrical energy so that it can be transported and distributed safely and efficiently. However, traditional transformers have low energy efficiency, which represents a waste of energy and an increase in the costs of distributors. Energy efficiency management is a set of actions that aim to reduce energy consumption in a process or system. In the case of energy distributors, energy efficiency management can be applied to various components of the electrical system, including transformers. The study and acquisition of more efficient transformers is an important energy efficiency management strategy for energy distributors, as it can bring various benefits, both for companies and society. To verify the technical-economic feasibility of acquiring more efficient transformers, tools such as the PDCA (Plan-Do-Check-Act) plan and the linear method for calculating depreciation were used. Complementary practical methods were used to analyze the electrical energy losses of these equipment and consequently to prove efficiency as a determining factor in the optimal solution under technical-economic criteria.
