1. A circuit system for measuring electrical voltage, comprising:
a voltage divider configured to receive, at an input, a first signal that represents the electrical voltage to be measured, and having a first switching element and a second switching element, the voltage divider being configured to assume a first state in which the first switching element is conductive and the second switching element is non-conductive, and a second state in which the first switching element is non-conductive and the second switching element is conductive, and the voltage divider is configured to output a second signal at an output situated between the first switching element and the second switching element;
an integrating element configured to receive the second signal and to output a third signal; and
an evaluating unit configured to accept the third signal and to evaluate the third signal to determine a value for the electrical voltage.
