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

This paper describes an on-line monitoring system which detects both partial discharges and the underlying power frequency leakage current on an insulator surface. This could allow degradation of the insulator performance to be monitored remotely. The sensing element would be a metal band fitted around the insulator close to the earthed terminal. High and low frequency components of current are separated and recorded in order that trends can be observed. A pollution model was devised which replicated the deposition of surface contamination on insulators in a practical laboratory experiment The effectiveness of the experimental technique for detecting pollution build up was studied using this arrangement.
