Estimativa das características do núcleo de transformadores a óleo através da potência

Abstract

This paper presents a empirical analysis applied to the currents of core transformer oil, checking the possibility of determining those characteristics by developing standards equations. Through those equations it will be possible to calculate the core currents without performing tests, the cost for each of those tests comes to R$1,000.00. This study will be based on the measurement of excitation, magnetization and iron currents that will be statistically analyzed and compared with values obtained directly from test methods. It was be presented both results by checking the proximity of the data collected by the forms described and concluding that the proposal is valid.
