摘要
提出了一种基于Faraday效应的集磁环结构的袖珍式光纤电流传感器,并就温度变化对它的影响进行了讨论。该传感器在电流有效值0~1000A的范围内进行了实验,实验结果表明其线性度相对偏差在±0.2%以内。利用该传感器对电流谐波进行了分析,结果和理论分析一致:存在奇数次谐波。
A portable optical fiber current transducer based on Faraday effects with magnetic concentrator is presented. The analysis of the results obtained for temperature influence on the measurement is performed. A test is performed according to the measured values of ac rms current up 1000A. The results illustrate the relative deviation of the system is within ±0.2%. The sensor is applied for the harmonic analysis of the current. The results are consistent with the analysis by the theory and demonstrate odd-order harmonic presence.
