In this paper it was examined the simulation, implementation and validation of the method of magnetic width-size shunt of varying length, as mechanism to reduce the losses caused by the leakage flux in the tank of a single-phase distribution transformer of 15 KVA. Initially through the simulation in 2D with the Finite-Element Method FEM, the behavior of the losses settled down in the walls of the tank of the transformer, with and without magnetic screen, and later on, through additional tests of laboratory, it was carried out the respective verification in the transformer. The analysis of the results obtained in this investigation shows that there is a significant impact in the reduction of the level of stray losses, with the implementation of the magnetic shunt and therefore such a methodology of selected mitigation of losses is adapted and viable technical and economically.
