Comparison of Dielectric Recovery After Arc Burning in SF6 Gas and Its Potential Alternatives

High Voltage, EarlyView.
ABSTRACT Although sulphur hexafluoride (SF6) exhibits exceptional insulating properties, it is a potent greenhouse gas. Therefore, studying alternatives to SF6 is critical for developing environmentally friendly high‐voltage electrical equipment.

Investigation of the Evolution Mechanism and Multiphysics Coupling in Tree‐Contact Single‐Phase‐to‐Ground Fault

High Voltage, EarlyView.
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.

Influence of Metal Wire on Interfacial Energy Transfer During Lightning Return-stroke Process

应用气象学报
Determining the influence of metal wires on interfacial energy transfer characteristics is crucial for the accurate assessment of lightning-induced damage. An experiment on return-stroke damage is designed using artificially triggered lightning with OGW (

A distinct negative leader propagation mode

Scientific Reports, 2021
The common phenomenon of lightning still harbors many secrets such as what are the conditions for lightning initiation and what is driving the discharge to propagate over several tens of kilometers through the atmosphere forming conducting ionized ...

No added cost: Emotion recognition in co‐occurring ADHD and ASD

British Journal of Clinical Psychology, EarlyView.
Abstract Objectives Facial emotion recognition (FER) is fundamental for social interaction, yet this ability is often impaired in attention‐deficit/hyperactivity disorder (ADHD) or autism spectrum disorder (ASD). While research has documented these difficulties, two key questions remain: Are these deficits specific to recognising emotions or do they ...

Searching for electromagnetic counterpart of LIGO gravitational waves in the Fermi GBM data with ADWO [PDF]

, 2016
The Fermi collaboration identified a possible electromagnetic counterpart of the gravitational wave event of September 14, 2015. Our goal is to provide an unsupervised data analysis algorithm to identify similar events in Fermi's Gamma-ray Burst Monitor ...

Lightning Triggering Related with Seismic Waves

2007 7th International Symposium on Electromagnetic Compatibility and Electromagnetic Ecology, 2007
This paper reports the trigger effects concerning rare high intensity sub-millisecond electromagnetic pulses associated with passage of seismic waves from earthquakes. The Malaysian LDN data have been studied together with earthquake USGS NEIC catalog, and space-time coupling of positive cloud-to-ground discharges (+CG) with exact seismic waves from ...

Laser-triggered lightning discharge

New Journal of Physics, 2002
Advances in ultrafast optics in recent years have revived a keen interest in laser-induced dielectric breakdown study. While it is widely accepted that femtosecond laser pulses with peak powers reaching gigawatts can propagate over tens of metres under laboratory conditions, the dynamics underlying this highly nonlinear phenomenon is yet not fully ...
