Resumo(s)
In the past few years, a considerable research effort has been devoted to the development
of transformer digital models in order to simulate its behaviour under transient
and abnormal operating conditions. Although many three-phase transformer
models have been presented in the literature, there is a surprisingly lack of studies
regarding the incorporation of winding faults. This paper presents a coupled electromagnetic
transformer model for the study of winding inter-turn short-circuits.
Particular attention will be given to the model parameters determination, for both
healthy and faulty operating conditions. Experimental and simulation test results
are presented in the paper, demonstrating the adequacy of the model as well as the
methodologies for the parameters determination.
