Abstract:
A fiber-optic voltage sensor suitable, in particular, for high-voltage measurement, having two connector contacts and a sensor axis, it being the case thata) the voltage sensor has at least one sensor element comprising a piezoelectric body and a sensor fiber fastened thereto, as well as several spacing elements, andb) the at least one sensor element and the spacing elements are arranged in an alternating fashion and one behind another along the sensor axis and are mechanically coupled, whereinc) the spacing elements are electrically conductive and make electric contact with the/each neighboring sensor element, andd) in order to form a high-voltage part of the voltage sensor which can be used outdoors, the arrangement of the sensor elements and spacing elements is surrounded by a high-voltage-proof dielectric and is provided with a protective shield.
