摘要
本文利用法拉第效应提出一种干涉型光纤电流传感器，使用平衡测试原理具有闭环反馈结构。它的主要优点是能够有效地消除费德尔常数和环境变化对传感器的不良影响，电流测量范围大、线性度好，在电力系统中有广泛的应用价值。
A fiber optic interferometric configuration for a current sensor utilizing the Faraday effect is described.The system is operated in a closed loop mode using the null measurement method.In this mode of operation scale factor errors due to changes in the Verdet constant of the fiber and environmental pertubations are effectively eliminated.The sensor may have many applications in electrical system,as measurements from low currents up to very high current are possible.
