Abstract

La présente invention concerne les dispositifs de protection de noeuds électriques. Le dispositif selon l'invention se caractérise essentiellement par le fait qu'il comprend des transformateurs d'intensité connectés à chaque ligne arrivant sur le noeud et un ensemble électronique traitant les informations électriques obtenues à la sortie des transformateurs et délivrant à sa sortie un ordre logique d'isoler ledit noeud lentement, quand un défaut est constaté au niveau du noeud ou rapidement quand il est constaté simultanément un défaut au niveau du noeud et un risque de saturation d'au moins un transformateur d'intensité. L'invention trouve une application avantageuse dans la protection des jeux de barres dans les réseaux de distribution de l'énergie électrique.
