Abstract

L'invention concerne un procédé pour influer sur les dispositifs (8, 10, 11, 15, 17, 18, 21, 23, 26, 28, 30, 31, 34, 39, 41) d'une installation haute tension (1), selon lequel dans une fenêtre de sélection (43), par exemple, des unités de commutation (15, 17, 18, 21) sont définies avec un paramètre commun, de nouvelles valeurs étant ensuite attribuées à ce paramètre commun directement ou par l'intermédiaire d'une relation de valeurs afin d'inverser, par exemple, l'état de commutation de chaque unité de commutation (15, 17, 18, 21), ce qui permet d'obtenir une influence rationnelle sur l'état de l'installation haute tension (1).
