Abstract

L'invention concerne un procédé de mesure du temps de commutation sur un commutateur à gradins en charge ainsi qu'un circuit de mesure approprié. Le procédé consiste à effectuer une commutation du commutateur à gradins en charge et à déterminer alors des courbes spécifiques de tensions de mesure ainsi qu'à définir leurs flancs. En comparant les flancs effectifs mesurés à des valeurs de consigne préalablement mémorisées de manière non volatile, il est possible de déterminer si la séquence de commutation du commutateur à gradins en charge objet du contrôle concorde avec les valeurs de consigne.
