Abstract

We report on the design and implementation of a novel hybrid electro-optical sensor for electric current. An all-fibre transducer is utilised to passively interrogate an air-core coil via a low-voltage piezoelectric multilayer. Peak Bragg reflections are strain-tuned by the Rogowski emf, allowing transducer interrogation and primary current reconstruction to be performed remotely and without active electronics at the sensor. The preliminary embodiment demonstrates long-distance, passive measurement of current for metering and protection applications, and retains the fibre transducer's capability for serial multiplexing.
