Perdas em transformadores nos sistemas de distribuição de energia elétrica: urbanos e rurais.

Abstract

performance of single phase and three phase transformers used in distribution systems of electrical energy in rural and urban areas, and an analysis of losses associated with its operation under linear and nonlinear loads. Also is presented a comparative analysis of technical and economic viability of amorphous alloy core single-phase distribution transformers, with identical power ratings, in replace to the traditional iron-silicon (FeSi) grain oriented (GO) core single-phase distribution transformers, particularly with respect to losses in the core, in order to reduce them and thus increase the energy efficiency, resulting in less need for electric power generation that, consequently, contributes to the reduction of greenhouse gases to the environment as CO² and SO².
