Abstract
a. Dispositif à relais avec comparaison de phase. b. Dispositif à relais, modifié, comprenant un circuit créant une première et une seconde limites de seuil de manipulation, qui sont toutes deux décalées d'une valeur de différentiation par rapport à l'axe nul, efficace de la courbe de courant passant à chaque extrémité de la partie de ligne protégée. Le décalage de l'un des niveaux de seuil de manipulation est choisi de façon à recevoir un courant d'incident de sortie, maximum, à une extrémité de la partie de ligne protégée, et que le décalage de l'autre limite de seuil de manipulation est choisi pour des amplitudes plus faibles du courant d'entrée. c. L'invention est destinée à protéger les réseaux de distribution d'électricité contre les incidents entre les phases ou entre une phase et la masse.
