Abstract

DISPOSITIVO INDUTIVO DE DETECÇÃO DE CORRENTE. A presente invenção refere-se a um dispositivo de detecção de corrente de baixo custo e alta precisão e métodos de uso e fabricação. Em uma modalidade, o aparelho de detecção de corrente compreende uma bobina do tipo Rogowski que é fabricada em segmentos de modo a facilitar o processo de fabricação. Em uma modalidade exemplar, os segmentos de aparelho de detecção de corrente são assimétricos em formato e/ou composição (por exemplo, formato, tamanho de bobina, e/ou configuração de enrolamento) de modo a representar as assimetrias em distribuição de campo magnético em torno de uma barra de barramento, ou acomodar seu formato em um fator de forma mais compacta, e/ou aperfeiçoar a imunidade aos efeitos de um campo magnético externo. Métodos de fabricar e usar o aparelho de detecção de corrente acima mencionados são também descritos.
