In this paper, it is presented a methodology for three-phase ditribution tranformer modeling, considering several types of tranformer configuration, to be used in algorithms of power flow in three-phase radial distribution networks. The paper provides a detailed dicussion about the models and the results from an implementation of the power flow algorithm. The results, taken from three differents networks, are presented for several transformer configurations and for voltage regulators as well.
