摘要：A sensor arrangement for measuring an electric voltage (U), wherein thepotential point, 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, towhich a comparator unit is connected which ascertains whether a first defined thresholdvoltage (U) is present at the capacitor, wherein the sensor arrangement is configuredsuch that it provides an output signal which is dependent on at least one chargingprocess of the capacitor and includes at least the information of the charging time forcharging the capacitor to the first defined threshold voltage.
