Title in Portuguese
Desenvolvimento de resistor shunt para medidas de correntes impulsivas em especial para aquelas oriundas de descargas atmosféricas
Keywords in Portuguese
Descargas atmosféricas
Medição de correntes impulsivas
Resistor shunt
Abstract in Portuguese
Este trabalho objetivou a construção de um resistor shunt dedicado a medir correntes impulsivas com valores de 2 kA a 100 kA. Esse resistor possui características gerais similares aos resistores shunt coaxiais convencionais descritos na literatura. No entanto, ele difere dos demais já desenvolvidos, por apresentar inúmeras inovações tecnológicas. Quando comparado com um resistor shunt Haefely® padrão, apresentou excelente estabilidade em toda a faixa de freqüência requerida, até 10 MHz, bem como, excelente resposta temporal.

The aim of this work was to construct a shunt resistor to measure impulsive currents with values from 2 kA to 100 kA, with general features similar to conventional coaxial resistors as described in the literature. However, it differs from resistors already developed because it shows many offers technological innovations. When compared to a should stand Haefely® shunt resistor, it presented great stability in all required frequency band to 10 MHz, as well as excellent temporal response.
