Abstract

The nonlinearities in the response of an interferometric fiber-optic current sensor associated with deviations of the light waves from perfect circular polarization are theoretically and experimentally investigated. The consequences for inherent temperature compensation of the Faraday effect by means of a non-90°-retarder are investigated for currents up to several 100 kA and temperatures between -40°C and 80°C. The results are of particular interest to sensors for high direct currents in the electro-winning industry where measurement accuracy to within ±0.1% is required up to 500 kA.
