Abstract

In this paper, a novel Fiber Bragg gratings (FBGs) high alternating current sensor is proposed to measure alternating current. The principle and sensing structure are introduced. The sensitivity of the high alternating current sensor is 13.8pm/A when the current is 1000A. The trend shows a good linearity between the wavelength shift and the square of the current value which is consistent well with the principle and indicates that the proposed sensor is capable of measuring high alternating current.
