Organic Representation as a Critical Media Approach to Leadership Studies in Popular Culture
ABSTRACT This article applies the critical media concept of organic representation to leadership studies as an analytic of how various creators in popular culture today are not just writing inclusive storytelling but, more notably, modeling new modes of production and self‐presentation that are actively challenging hegemonic industry practices and ...

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 ...

Rare Lightning and Convection Characteristics During Two Successive Tornadoes in Southern China
ABSTRACT Systematic investigations into lightning characteristics of tornado storms in China remain scarce. This study comprehensively analyses rare lightning behaviour and overshooting top characteristics for two successive tornadoes during a long‐lived supercell in southern China on 27 April 2024.

Computation of electromagnetic fields from lightning discharge
Electromagnetic fields from lightning can couple to electrical systems and produce transient overvoltages, which can cause power and telecommunication outages and destruction of electronics.

ABSTRACT Tree‐contact single‐phase‐to‐ground fault (TSF) is a common and hazardous type of failure in distribution networks. TSF is likely to occur when overhead conductors contact moist tree branches, potentially leading to insulation breakdown, posing serious threats to grid safety.

Lightning Impulse Ageing of HV Cable Insulation
Lightning impulses can lead to accelerated ageing of extruded cables. Electrical behaviour of a dielectric material when experiencing a lightning impulse is different to that for DC or power frequency applied voltages.

ABSTRACT This paper investigates the generation mechanism of quasi‐power‐frequency resonant overvoltage triggered by multiple lightning strikes in high‐voltage alternating current (HVAC) systems equipped with shunt reactors. Based on field measurements from a 500 kV AC system, equivalent and simplified circuit models have been established to analyse ...

A Deep Learning Model for Lightning Location and Peak Current Estimation from Induced Overvoltages
A novel methodology for the determination of lightning return stroke strike position and peak current using Deep Learning (DL) techniques is introduced in this contribution. The underlying concept consists in exploiting the voltage transients produced by
