Abstract
(DE)
Sensoranordnung zum Messen einer elektrischen Spannung (UKlemm), wobei der Potentialpunkt (1), an welchem die elektrische Spannung relativ zu einem definierten elektrischen Potential, insbesondere relativ zur Masse, gemessen werden soll mit einem Kondensator (2) verbunden ist, an welchen eine Komparatoreinheit (3) angeschlossen ist, die erfasst, ob eine erste definierte Schwellspannung (URef) an dem Kondensator (2) anliegt, wobei die Sensoranordnung so ausgebildet ist, dass sie ein Ausgangssignal bereitstellt, das abhängig von wenigstens einem Aufladevorgang des Kondensators (2) ist und zumindest die Information der Ladezeit zum Aufladen des Kondensators bis zur ersten definierten Schwellspannung umfasst.
(EN)
A sensor arrangement for measuring an electric voltage (Uterm), wherein the potential point (1), at which the electric voltage relative to a defined electric potential, in particular relative to earth, is intended to be measured, is connected to a capacitor (2), to which a comparator unit (3) is connected which ascertains whether a first defined threshold voltage (URef) is present at the capacitor (2), wherein the sensor arrangement is configured such that it provides an output signal which is dependent on at least one charging process of the capacitor (2) and comprises at least the information of the charging time for charging the capacitor to the first defined threshold voltage.
(FR)
L'invention concerne un système de capteur pour mesurer une tension électrique (UKlemm), le point du potentiel (1) auquel la tension électrique doit être mesurée par rapport à un potentiel électrique défini, en particulier par rapport à la masse, étant relié à un condensateur (2) auquel est raccordé une unité comparatrice (3) qui détecte si une première tension seuil définie (URef) est appliquée au condensateur (2), le système de capteur étant conçu de manière à fournir un signal de sortie qui dépend d'au moins un processus de charge du condensateur (2) et comprend au moins l'information relative au temps de charge pour charger le condensateur jusqu'à la première tension seuil définie.
