Abstract

Patente de Invenção: "SENSOR DE CORRENTE". Um medidor fiscal de eletricidade é descrito para medir a energia fornecida para um circuito de utilização. A corrente do circuito de utilização flui através do enrolamento primário de um transformador e induz uma EMF indicativa da corrente fluindo no enrolamento secundário. O enrolamento secundário compreende uma bobina de percepção, disposta para acoplar-se mais fortemente com o primário e uma bobina de cancelamento que possuir produtos da área das voltas iguais e opostos de modo a proporcionar uma resposta nula aos campos magnéticos externos. As bobinas estão dispostas de modo que seus eixos magnéticos estejam co-localizados e alinhados de modo que elas também proporcionam uma resposta nula aos campos magnéticos externos possuindo um gradiente do campo.
