Abstract

The invention relates to a sensor (3) for measuring a voltage in a HV/MV power network in a separable connector (2), the sensor comprising: —an adapter element (11) comprising a high voltage connection adapted to be mechanically and electrically coupled to a high voltage conductor (7) of the separable connector (2) and to receive HV/MV voltage from the separable connector, —a sensor body (12) adapted to be mechanically and electrically coupled to the adapter element (11) and comprising a divider assembly (24) with a plurality of discrete impedance elements, which are electrically connected in series such as to be operable as a voltage divider for sensing a voltage and a low voltage connection (42) configured to provide a low voltage signal corresponding to a high voltage signal present in the HV/MV power network, wherein the adapter element (11) and the sensor body (12) are separate elements that are adapted to be installed to the separable connector (2), wherein the adapter element is configured to be installed between the separable connector and the sensor body.
