Paper Abstract

An optical current sensor has been designed and tested. This device, which employs the Faraday effect in optical fibre to measure electrical current, is intended to be applied in power system protection equipment; it is regarded as a potential replacement for the iron cored current transformer in certain applications. A novel polarization analyser arrangement is included in the optical current sensor. The theory of operation of this component is presented and it is shown that a simple graphical representation of the state of polarization may be produced in real time. The operation of the current sensor is described and pre-installation test results are presented.
