Abstract (en)
[origin: WO2012130990A1] 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.
