Paper Abstract

An optical fibre current sensor based on the Faraday effect has been designed and tested. The sensor, which is intended for use in high voltage power distribution systems, makes use of a single-mode fibre in the sensing region. A novel polarization analyser arrangement is included in the current sensor and the operation of this component is described. It is shown that a simple graphical representation of the state of polarization can be produced in real time. Preinstallation test results of the optical current sensor are given.
