| Abstract: | This paper proposes a novel optical fiber heavy current sensor based on a synthetic effect of the linear electro-optic effect and antipiezoelectric effect of LiNbO3 crystal Faraday electromagnetic induction principle, and proves the feasibility of this sensor on theory and experiment. The linearity of this sensor is better than 1.09% in measurement range from 50A to 300A. In addition it can mepsure not only alternating current, but also pulse current. |
