Abstract

L'invention concerne un procédé et un appareillage de protection sélective contre les défauts à la terre dans réseaux électriques dont le neutre est relié à la terre par une résistance Le procédé est caractérisé en ce qu'on détecte l'apparition d'une tension homopolaire éventuelle, on détermine sa polarité pendant des intervalles de temps donnés, on détecte les courants résiduels dans les antennes du réseau, on détermine leur polarité, on la compare à celle de la tension homopolaire et on traite le résultat pour séparer l'antenne du reste du réseau. L'appareillage est caractérisé en ce qu'il comporte un capteur et un ensemble de moyens pour capter et traiter un signal de tension homopolaire, et autant de capteurs et d'ensembles de moyens pour capter et traiter un signal de courant résiduel, et de dispositifs de séparation, qu'il y a d'antennes. L'invention est applicable aux cas où il est nécessaire que l'élévation de potentiel des masses soit très faible, par exemple dans les mines.
