Targeting property flood resilience in flood risk management
Journal of Flood Risk Management, Volume 14, Issue 3, September 2021., 2021 Abstract In this article, we evaluate property flood resilience (PFR) to manage pluvial and combined tidal/ fluvial flood risks. We achieve this by evaluating flood risk and intervention targeting strategies across a case study in Bristol (UK) using data types generally available for preliminary option assessment.

Procedia Engineering, 2013 AbstractDistribution transformer is the key element in the electricity transmission throughout the nation. Hence, serious attention for the transformer condition monitoring is a crucial. With an occurrence of short-circuit in the power system, the transformer active parts such as core and winding will experience a mechanical movement created by the ...

Methodology to locate and quantify radial winding deformation in power transformers
High Voltage, Volume 2, Issue 1, Page 17-24, March 2017., 2017 Frequency response analysis (FRA) is a tool that can be used to detect changes within the structural geometry of a transformer. One application of FRA is to detect winding displacement after the transformer experiences an overcurrent event. This paper proposes a methodology which will facilitate both locating and quantifying winding deformation.
