Abstract
Optical fiber sensors for the measurement of electric power are reviewed. We focus on the direct measurement approach, which allows electric-power-sensing signal to be directly obtained from light wave canier. Based on Pockels and Faraday effects, three kinds of optical electric-power sensors have been developed, including the combination of a Faraday medium with a Pockels medium in cascade; utilization of the single crystal exhibiting both Faraday effect and Pockels effect; and application of the electro-optic crystal multiplier. Potential applications of optical electric-power sensors lie in electric power industry and the field of electromagnetic compatibility. Measurement of active power, uncertainty and effects of temperature variations and vibration are key problems to be solved for optical electric-power sensor. Some corresponding solutions are proposed.
