O transformador: teoria, construção e análise do rendimento.

In this work, the stages of construction of a nuclear-type transformer were presented in detail and how electrical measurements can be used to extract relevant parameters from it. The physical theory for the model of a real transformer has been briefly described. Theoretically, it was concluded that this can be treated as an ideal transformer plus external impedances. In the experimental analyses, it was possible to obtain the resistances and reactances of the coils and the core and with this estimate the transformer efficiency. [ABSTRACT FROM AUTHOR]
