Design of a novel fiber Bragg grating current sensor

提出了一种新型的光纤光栅高压电流传感器。该系统由Bragg光纤光栅电流测量部分和温度补偿部分组成。在测量过程中,采用了匹配光栅解调方法,其动态测量范围比通常的干涉法光纤电流传感器大,且系统不受外界电磁干扰的影响,可实现高压电流的在线测量。

A novel high-voltage current fiber Bragg grating sensor is proposed. The system is composed of the current measurement and the temperature compensator. It used the demodulate method of match grating in the measuring, So compared with the common optical fiber current sensor, this system has a large dynamic range extended, and is out of the. effect of the electromagnetism. The system can measure high-voltage current on-line.
