Um wattímetro microcontrolado para aplicações em ensaios de transformadores de potência.

Abstract

This report presents a prototype of a digital power meter single phase for use in the testing of distribution transformers. The prototype of the meter was based on a digital platform microcontrolled low cost, and was made using components and sensors also reduced cost. The platform microcontrolled allowed the acquisition and processing of data relating to the electrical distribution transformer. The results were satisfactory, since their comparison with other measuring errors generated sufficiently low.
