Open Access research with a real impact on health...

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 Physical Activity for Health Group based within the School of Psychological Sciences & Health. Research here seeks to better understand how and why physical activity improves health, gain a better understanding of the amount, intensity, and type of physical activity needed for health benefits, and evaluate the effect of interventions to promote physical activity.

Abstract

A theoretical evaluation of a novel, all-optical differential current protection scheme employing low voltage piezoelectric transducers, fiber Bragg grating sensors and Rogowski coils is presented in this paper. The optical power reflected from the sensors is monitored by means of a single photodetector, whereas fault occurrence is detected by a simple optoelectronic threshold detector. We demonstrate through simulations that an immediate response to an increase in differential current can be achieved even at low voltage levels such as these generated by Rogowski coils providing a low-cost and fast-acting fault detection system.
