Abstract

Fiber-optic current sensor was developed using the Faraday effect to measure the electrical current on high-voltage lines. A twisted single-mode optical fiber was used as a sensor coil to suppress birefringence effect, enhancing performance against environmental perturbations. In this paper, we report the basic design considerations and the preliminary experimental results carried out in the 1000 A input current range.
