Filtro para ensaio de descargas parciais em transformadores de potência

Abstract

This work aims at the development and implementation of an active filter to limit the cutoff frequency for performing the measurement of partial discharges in power transformers in accordance with the requirements of official entities. Due to the transformers market is in an increasingly bitter dispute between manufacturers, the difference from one to the other is the quality of your product. With this control partial discharge is in accordance with current standards, ensures a degree more in this capacity, ensuring better performance and a longer service life of the transformer.
