Estudo do ruído em transformadores de distribuição da classe 15kV em função da indução do núcleo

Abstract

This work aims to study the main sources of noise in the distribution transformer of 15kV class, the processes required for carrying out the tests in the manufacturer's laboratory as set by the NBR 7277/2013. Develop an algorithm for simulation of noise levels transformers through its constructive aspects, showing how noise behaves by varying the magnetic induction in the core plate.Make the comparison between the values obtained with the developed algorithm and the values measured in the manufacturer's laboratory, checking its efficiency and the values are consistent with those required by the NBR 5356-3 / 2014. Proposing suggestions for improvement for future projects.
