Open Access research with a European policy impact...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of Open Access research papers by Strathclyde researchers, including by researchers from the European Policies Research Centre (EPRC).

EPRC is a leading institute in Europe for comparative research on public policy, with a particular focus on regional development policies. Spanning 30 European countries, EPRC research programmes have a strong emphasis on applied research and knowledge exchange, including the provision of policy advice to EU institutions and national and sub-national government authorities throughout Europe.

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.
