Abstract in Portuguese
Neste trabalho mostrou-se a viabilidade técnica da construção de um sistema totalmente novo para medir altas tensões e correntes em linhas classe 15 kV, cuja filosofia fundamenta-se no acoplamento de dois sistemas de medidas, um convencional e outro eletro-óptico. O sistema convencional consiste em divisores de tensão e anéis captores e o eletro-óptico, em LEDs, resistores, fibras ópticas e receptores. Este sistema foi totalmente testado em laboratório e apresenta como principais características baixo custo, facilidade de instalação e versatilidade. Também neste trabalho foram desenvolvidos dois programas computacionais para a aquisição de dados através de placas GPIB e A/D. Estes programas também permitem processar os dados, fornecendo relatórios sobre tensões, correntes, potências e ângulo de potência.

Abstract in English
In this work, the technical feasibility of the development of a novel system measuring of high voltages and currents in 15 kV distribution lines was presented. The system is basically the combination of two other systems, one conventional and other electro-optical. The conventional subsystem is based on voltage dividers and magnetic rings while the electro-optical subsystem uses LEDs, resistors, optical-fibers and photodetectors. The system was completely tested in laboratory and its main characteristics are low price, easy of installation and flexibility. Two softwares for data acquisition by GPIB and A/D boards were also developed. They can provide reports on voltages, currents, power and phase-power.
