Transformadores: dos primeiros protótipos aos atuais modelos a estado sólido.

Abstract

Transformers are installed at both urban and rural centers, playing an essential role on the operation of electrical network. On efficiency energy path, several producers and researchers strive to predict, measure and reduce the energy loss associated with the operation of the equipments. Regarding the use of new magnetic materials, amorphous metals are a viable technology to replace the traditional silicon alloys, while nanocrystallines alloys has the potential to be used in solid state models. In this work, by means of literature survey, considerations on the development of distribution transformers in the context of energy efficiency are exposed on timeline, presenting analytical and computational studies published over the years about the use of new magnetic circuit materials.
