Abstract

La présente invention vise à proposer : un dispositif de commande de la commutation électrique qui peut éviter la production de tensions/courants transitoires qui peuvent provenir d'une divergence entre les valeurs estimées de la tension entre pôles et la tension réelle entre pôles après interruption du courant ; ainsi qu'un procédé de commande pour la fermeture du dispositif. Lorsqu'un temps prédéterminé, calculé à l'avance en fonction de la constante de temps de décroissance de la tension résiduelle sur une ligne de transmission électrique, s'est écoulé après un instant d'interruption du courant et lorsque la tension du côté de la charge à l'instant d'interruption du courant et après est un signal de courant continu et la tension du côté de la charge à l'instant d'interruption du courant et après, ainsi que sur une certaine période de temps, présente un comportement de convergence vers zéro à au moins une certaine vitesse, la valeur estimée de la tension du côté de la charge, à l'introduction suivante, est estimée être à zéro.
