Paper Abstract

This paper presents an optical voltage transformer based on the Pockels-effect with a polarimetric signal evaluation. The electrically passive sensor head uses a number of bulk optical sensor crystals which are spatially distributed along the primary voltage drop to minimize the electrical field strength inside the sensor head and reduce electrical insulation expenses. The adaptation of the sensor head's sensitivity is managed by adjusting the absolute crystal length and by cascading similar sensor elements.
