Fear or feast: small mammal activity increases in the presence of carcasses despite increased threat of predation by black‐backed jackals

Wildlife Biology, EarlyView.
Food acquisition is arguably the most important, and among the riskiest behaviours for most mammals. Carcasses are an ephemeral resource for many scavengers, particularly black‐backed jackals Lupulella mesomelas that prey on small mammals. Landscape of fear theory suggests that prey species should reduce their activity in areas of high predator ...

A Dual‐Frequency Sensitivity Model for Optical Fibre Ultrasonic Sensors in Power Transformer Partial Discharge Detection

High Voltage, EarlyView.
ABSTRACT The detection of partial discharges (PD) on the power transformer tank demands higher sensitivity in ultrasonic detection. To target the detection frequency band for sensor optimisation and enhance sensitivity, this paper presents a dual‐frequency sensitivity model for optical fibre ultrasonic sensors.

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

High 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 ...
