Abstract :
This paper presents the relation between the losses and capacitances in three-phase distribution transformers. The motivation stems from the search of projects with reduction of losses and economic viability as the variation of the constructive parameters, which varies the losses consequently, changes of capacitances. This paper aims to obtain knowledge about how the changes in the design whose goal is loss reduction, change the capacitances and initial distribution of voltage on the winding, parameters that may change the behavior of transformers especially when under disturbances of high levels frequency.
