Development of fuel saving bottom trawl

open access: yes, 2002
This paper was aimed at developing bottom trawl designs, for the Italian Fisheries that reduced fuel consumption. The new designs will include the use of new high strength material and the use of larger meshes in net areas where no negative effect on catching power is foreseen. It is essential that the new designs combine the features of large headline

Evaluation Methodology, Numerical Verification and Retrofilling Procedure for Power Transformers to Ensure K‐Class Flame Retardancy and Environmentally Friendly

open access: yesHigh Voltage, EarlyView.
ABSTRACT With increasing demands for fire safety and environmental friendliness, retrofilling transformers with alternative insulating liquids has become a growing trend. However, retrofilling power transformers remains uncertain, as more residual mineral oil compromises K‐class flame retardancy, and its impact on environmental performance has yet to ...

Arc Resistance Enhancement of Converter Transformer Tank Through Structural Improvements: Simulation and Experimental Validation

open access: yesHigh Voltage, EarlyView.
ABSTRACT Currently, limited research exists on the structural response and protection methods of the converter transformer tank for ± 800 kV ultra‐high voltage direct current transmission project to high energy arc faults. This research investigates the dynamic response and the vulnerable areas of the ultra‐high voltage converter transformer under the ...

Electrical Breakdown Analysis of Emerging Oil–Paper Insulation Systems

open access: yesHigh Voltage, EarlyView.
ABSTRACT This investigation addresses the effect of particulate additives on the electrical breakdown strength of the oil impregnated insulation paper system. The morphological complexity is addressed by converting data from scanning electron microscope images to a data set suitable for numerical simulation analysis. Then, by using the conventional oil‐

Offshore wind farm avoidance by a discard‐feeding seabird is independent of local fishing activity

open access: yesJournal of Animal Ecology, EarlyView.
Fishing is not allowed within wind farms; therefore, discard‐feeding seabirds may appear to avoid wind farm areas. We found that most Lesser Black‐backed Gulls avoided the wind farm area, but not each individual in each period. Avoidance of the wind farm was not driven by fishing exclusion within its perimeter.
