Abstract

Un détecteur de circuit défectueux (10) comportant un indicateur isolé électriquement et positionné à distance (14) détecte des courants de défaut dans un conducteur contrôlé (18). Lorsqu'un défaut d'une ampleur prédéterminée est détecté, une impulsion lumineuse est transmise du détecteur à l'indicateur par l'intermédiaire d'un câble à fibre optique (16) dans lequel, lors de la réception, l'impulsion est convertie en une impulsion électrique faisant indiquer à l'indicateur un état de ''défaut de fonctionnement''. Un circuit de remise à l'état initial (56) se trouvant dans l'indicateur remet ce dernier à l'état initial à intervalles réguliers, dans l'état ''normal'', tant qu'une tension minimum prédéterminée passe dans le conducteur contrôlé. Le détecteur comprend un circuit de compensation de température (150) ainsi qu'un circuit de filtre passe-bas (160) afin d'empêcher une fausse manoeuvre due à des températures ambiantes variables ou à des phénomènes transitoires de haute fréquence. Un circuit d'essai (48, 50, 34) permet au personnel d'entretien de tester sur le terrain le dispositif avec le conducteur contrôlé à l'état alimenté.
