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.

Evaluating the Inter-Resonance Characteristics of Various Power Transformer Winding Designs

IEEE Access, 2021
Resonance is a very familiar phenomenon in electrical circuits that occurs when a frequency of incoming signal is similar to the natural frequency of the electrical circuit. When resonance occurs, excessive over-voltage may appear. Resonance over-voltage

Online sweep frequency analysis testing on UPS for resilience

Measurement: Sensors, 2021
Resilience in the context of power systems involves several aspects of design, control, and monitoring. The uninterruptible power sources (UPS) are mostly adopted for several applications, to prevent data loss, to temporary power providing for mission ...

Power transformer geometry monitoring of active parts by SFRA method [PDF]

Zbornik Radova: Elektrotehnički Institut "Nikola Tesla", 2014
During regular operation, power transformer windings are continuously exposed to electromechanical stresses and vibrations. Surges during lightning or short circuits may cause the weakening of the mechanical structure and the mechanical reinforcing parts

Integrated Transformer Health Estimation Methodology Based on Markov Chains and Evidential Reasoning

Mathematical Problems in Engineering, Volume 2020, Issue 1, 2020., 2020
Due to the large number of power transformers (ETs) in the distribution system, there is a need for a relatively simple representation of the status of each unit in order to more easily determine where and how to allocate the budget for preventive and corrective maintenance.

Flood management consideration in sustainability appraisal and strategic environmental assessment in England and Scotland [PDF]

, 2014
The impact of flood events in the UK has drawn attention to limitations associated with traditional flood defence regimes. In recognition of this there has been a significant level of advocacy for a systems based approach which assumes a greater role for
