Abstract

En particulier, l'invention concerne un procédé comprenant les étapes consistant à obtenir ou à détecter des informations de fonction qui indiquent une ou plusieurs informations acoustiques, lesdites informations acoustiques étant associées à un disjoncteur ; à demander des informations cibles qui indiquent une ou plusieurs informations acoustiques sur le disjoncteur, lesdites informations acoustiques représentant l'état cible du disjoncteur ; à comparer les informations de fonction obtenues ou détectées avec les informations cibles demandées sur le disjoncteur ; à demander des informations de résultat au moins partiellement sur la base de la comparaison, les informations de résultat indiquant un état de fonctionnement du disjoncteur, et les informations de résultat représentant en outre si une fonction correcte du disjoncteur a été déterminée ou non en tant que partie de la comparaison ; et à émettre ou à déclencher la sortie des informations de résultat déterminées. L'invention concerne également un dispositif et un système comprenant ledit dispositif pour la mise en œuvre du procédé.
