This article has as objective point out the main sources of noise in the distribution transformers of 15kV class, describing the processes required to carry out the tests in the manufacturer's laboratory with all requirements set by the NBR 7277/2013. Through the implementation of an algorithm for simulation of noise levels considering its constructive aspects, showing their behavior by varying the magnetic flux density in the core sheet. It will also be conducted to compare the values found with the developed algorithm and the values measured in the manufacturer's laboratory, verifying their effectiveness, and whether they are in accordance with the NBR 5356-3 / 2014.
