Fiber-Link Vibration Immunity for an Extrinsic Faraday Current Sensor

  • Norman Fisher

Abstract

Optical current sensors utilising the Faraday effect are of considerable interest to the power distribution industry for measuring AC currents, owing to their inherent galvanic isolation of the sensor head from ground potential, lack of hysteresis and low cost,2.
