Abstract

Due to the widespread and easily use of computer calculations, numerical models are fundamental tools for a great number of subjects under study. In order to study transformers thermal loss of life, complex models taking into account electrical and thermal characteristics are required. Moreover, the precision of thermal models is dependent upon the exactitude of the parameters. The work presented in this article shows that, through electromagnetic similitude laws, for a homogeneous series of transformers with different rated powers, the main parameters required for the thermal model can be obtained
