Abstract

aparelho e processo de eliminação de corrente invasiva magnetizante. a presente invenção provê um aparelho de eliminação de corrente invasiva magnetizante (6), que elimina uma corrente invasiva magnetizante de um disjuntor (2) do tipo de operação coletiva, trifásico, para abrir e fechar uma conexão entre um barramento de fonte de energia (1) e um transformador de conexão woodbridge modificado (3), e o aparelho mede uma voltagem de corrente alternada, trifásica do barramento de fonte de energia (1), calcula os fluxos magnéticos estáveis do transformador de conexão woodbridge modificado (3), calcula os fluxos magnéticos residuais, após desconexão do transformador de conexão woodbridge modificado (3), e fecha o disjuntor (2), quando as polaridades dos fluxos magnéticos estáveis ficam iguais às polaridades dos fluxos magnéticos residuais em todas as linhas.
