The study of the electrical phenomena that originate during the operation of the transformers is of vital importance to predict the consequences that these will bring and to improve the design of the system and of the transformer itself. To carry out these studies it is necessary to use existing simulation tools. The accuracy of the response of the simulation process depends on the degree of detail and the veracity of the data, as well as the type of mathematical model used, so it is necessary to obtain these data and their application in the most suitable model for the simulation of each phenomenon. This paper presents the results of a project that consisted in obtaining, through simulation, the impulse voltage distribution within the transformer windings from a detailed model with the final objective of verifying the effectiveness of the insulating systems used in the transformers prototypes used.
