Abstract

La présente invention concerne un procédé de coupure sécurisée d'un réseau électrique, et un dispositif de sécurité associé, plusieurs composants étant raccordés au réseau électrique. Ces composants contiennent au moins une source d'énergie électrique (12) et au moins un consommateur électrique (14, 16, 18), et la source d'énergie électrique (12) est coupée ou déconnectée du réseau électrique (20), lorsqu'une boucle de ligne de sécurité (26) traversant les composants électriques est coupée. Selon l'invention, la boucle de ligne de sécurité (26) est contrôlée pour établir si une coupure s'est produite en raison d'une coupure interne de la boucle de ligne de sécurité (26) à l'intérieur de la source d'énergie électrique (12) ou en raison d'une coupure externe de la boucle de ligne de sécurité (26) à l'intérieur du consommateur électrique (14, 16, 18).
