Abstract

"DISPOSITIVO DE MEDIçãO PARA MEDIR CORRENTE DIFERENCIAL, UM MóDULO DE DESARME QUE COMPREENDE UM TAL DISPOSITIVO DE MEDIçãO E UMA UNIDADE DE DISTRIBUIçãO QUE TEM UM TAL MóDULO". A presente invenção refere-se a um dispositivo para medir uma corrente diferencial (9) projetado para medir a corrente diferencial em pelo menos duas linhas de corrente (25), compreendendo um primeiro circuito magnético (16) projetado para circundar as linhas de corrente (25), que forma um circuito primário de um transformador, um primeiro enrolamento secundário (11) enrolado ao redor do dito circuito magnético e que forma o circuito secundário do transformador, uma blindagem metálica (10) que circunda o primeiro enrolamento secundário (11) e o circuito magnético (16). O dispositivo para medir a corrente diferencial (9) além disso compreende pelo menos um segundo enrolamento secundário (2) que circunda pelo menos uma parte da blindagem metálica (10). Este segundo enrolamento forma um segundo circuito magnético de pelo menos um segundo sensor de corrente projetado para suprir um sinal elétrico representativo de uma corrente que flui em pelo menos uma linha de corrente (25).
