Leading national thinking on politics, government & public policy through Open Access research

Strathprints makes available scholarly Open Access content by researchers in the School of Government & Public Policy, based within the Faculty of Humanities & Social Sciences.

Research here is 1st in Scotland for research intensity and spans a wide range of domains. The Department of Politics demonstrates expertise in understanding parties, elections and public opinion, with additional emphases on political economy, institutions and international relations. This international angle is reflected in the European Policies Research Centre (EPRC) which conducts comparative research on public policy. Meanwhile, the Centre for Energy Policy provides independent expertise on energy, working across multidisciplinary groups to shape policy for a low carbon economy.

    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.
