A three‐dimensional direct lightning strike model for lightning protection of the substation

open access: yesIET Generation, Transmission & Distribution, 2021
Lightning strikes to a substation happen frequently, which has a serious impact on the safety of the power system. Therefore, it is important to evaluate the effect of the direct lightning to the substation for the sake of protection.

Simulation of Cloud-to-Ground Lightning Strikes to Wind Turbines Considering Polarity Effect Based on an Improved Stochastic Lightning Model

open access: yesAtmosphere, 2023
The accurate determination of the annual lightning flash number to a wind turbine is essential for designing proper lightning protection measures. However, the method to assess the lightning risk of wind turbines recommended by the IEC is not associated ...

MXene Reinforced Thermosetting Composite for Lightning Strike Protection of Carbon Fiber Reinforced Polymer

open access: yesAdvanced Materials Interfaces, 2021
Ti3C2 – a member of the MXenes (2D transition metal carbides and nitrides) family, is investigated as an effective filler to improve the electrical, mechanical, and thermal properties of divinylbenzene (DVB) thermosetting resin.

The response of zircon to the extreme pressures and temperatures of a lightning strike

open access: yesScientific Reports, 2021
Hypervelocity impacts can produce features in zircon that are not normally produced by endogenic processes. However, lightning can also induce extreme pressure–temperature excursions, and its effect on zircon has not been studied.

Modeling of PV Module and DC/DC Converter Assembly for the Analysis of Induced Transient Response Due to Nearby Lightning Strike

open access: yesElectronics, 2021
Photovoltaic (PV) systems are subject to nearby lightning strikes that can contribute to extremely high induced overvoltage transients. Recently, the authors introduced a 3D semi-analytical method to study the electromagnetic transients caused by these ...

Effect of SWCNT-Tuball Paper on the Lightning Strike Protection of CFRPs and Their Selected Mechanical Properties

open access: yesMaterials, 2021
The main aim of this work was the investigation of the possibility of replacing the heavy metallic meshes applied onto the composite structure in airplanes for lightning strike protection with a thin film of Tuball single-wall carbon nanotubes in the ...

Carrying the Moral Burden of Safe Fieldwork

open access: yesThe Bulletin of the Ecological Society of America, Volume 104, Issue 1, January 2023., 2023
Abstract Fieldwork in ecology and the environmental sciences often leads to negative physical and emotional outcomes for workers. I argue that this is largely due to an abdication of responsibility on the part of their supervisors, and that supervisors are charged with carrying three interlinked moral burdens: first, the duty of promoting safety ...

Canadian contributions to environmetrics

open access: yesCanadian Journal of Statistics, Volume 50, Issue 4, Page 1355-1386, December 2022., 2022
Abstract This article focuses on the importance of collaboration in statistics by Canadian researchers and highlights the contributions that Canadian statisticians have made to many research areas in environmetrics. We provide a discussion about different vehicles that have been developed for collaboration by Canadians in the environmetrics context as ...

Lightning strike probability and current simulation for simple structures and floating roof tank [PDF]

open access: yes, 2021
Air terminations must be strategically positioned at high-risk points to prevent lightning bypass. The likelihood of a direct lightning strike to points on a building can be evaluated using the dynamic electro-geometrical model (DEGM), which considers ...

Global ground strike point characteristics in negative downward lightning flashes – Part 2: Algorithm validation

open access: yesNatural Hazards and Earth System Sciences, 2021
. At present the lightning flash density is a key input parameter for assessing the risk of occurrence of a lightning strike in a particular region of interest. Since it is known that flashes tend to have more than one ground termination point on average,
