Correlated Transient Response of Buried Cables and Lightning Channel Radiation of Return Strokes of Five Rocket‐Triggered Lightning Strikes

High Voltage, EarlyView.
ABSTRACT Data from five rocket‐triggered lightning flashes are adopted to analyse the correlated transient response of buried cables and lightning channel radiations. These five flashes have the same termination point that is right above the buried cables and involve a total of 32 return strokes.

A Method for Separating Multisource Partial Discharges in a Substation Based on Selected Bispectra of UHF Signals

Applied Sciences, 2020
A method for separating multisource partial discharges (PDs) in a substation is proposed based on selected bispectra of ultrahigh frequency (UHF) electromagnetic waves. Bispectra are sensitive to Gaussian noises and processes of symmetrical distribution.

Regional Infrared and Visible Image Registration for Distribution Substation Areas With Wide Depth of Field

High Voltage, EarlyView.
ABSTRACT Infrared and visible image registration is a key task in automated distribution network inspection. Previous approaches typically apply a single homography to align infrared and visible images leading to local misalignment. To address this, this study proposes a novel region‐based registration algorithm specifically designed for wide‐depth ...

Optimized early detection of aquatic invasive species using a community rarity index

Ecological Solutions and Evidence
Following their introduction, invasive species management is most successful and cost‐effective when new invaders are detected while still rare. Given the low capture probability for extremely rare species, early detection programmes for aquatic invasive

Transient thermal modelling of substation connectors by means of dimensionality reduction [PDF]

, 2017
This paper proposes a simple, fast and accurate simulation approach based on one-dimensional reduction and the application of the finite difference method (FDM) to determine the temperatures rise in substation connectors.
