Abstract

A measuring device (10) for measuring voltage in a high-voltage part (22) surrounded by an electric field comprises a capacitive sensor (11) and a signal converter (13). The sensor includes an inner electrode (12) with a surrounding screen electrode (14). In the screen electrode, which is connected to a controllable reference potential, an opening (16) is provided which, during measurement, is directed towards the high-voltage part (22). By sensing a directed part of the electric field penetrating through the opening of the screen electrode into the inner electrode, the voltage of the high-voltage part (22) is measured at insulation distance.
