Procedimentos de medição e análise de ruído em transformadores de alta potência

Abstract

Transformers are essential parts of all existing power system, due to the equipment, it is possible to lower and raise the voltage to desired levels for a lot of applications. All transformers in operation mode emit a noise, the higher is the potency of the transformer, the greater its noise level. The noises in transformers are currently a major concern, there are regulatory rules that stipulate limit values of intensity of noise level. Thus is presented in this work, a study in order to demonstrate the importance of measuring noise levels in high power transformers.
