Paper Abstract

In this paper, we discuss the all-fiber approach to current sensing for high voltage applications. We present different sensors, based on the Faraday effect, which allow to perform measurements without any contact or linkage between the fiber and the line. This is obtained by an accurate control of the bending birefringence in the sensing coil and by a proper design of its shape. Using a multimode laser diode and a polarization readout scheme,the typical sensitivity is 1A (rms), with a dynamic range up to three decades and a bandwidth of 10 KHz. These performances are adequate both for steady-state measurement and transient monitoring.
