We propose an open-loop fiber optic current sensor (FOCS) using FBG and a 2-g bar of Terfenol-D with enhanced sensitivity for high-voltage transmission lines. The developed FOCS presented a linearity error of 2.35%, a resolution of 0.57% FSR, and a transient response of 1.5 ms in the range of 25-400 Arms.
