Electrical Breakdown Analysis of Emerging Oil–Paper Insulation Systems

High Voltage, EarlyView.
ABSTRACT This investigation addresses the effect of particulate additives on the electrical breakdown strength of the oil impregnated insulation paper system. The morphological complexity is addressed by converting data from scanning electron microscope images to a data set suitable for numerical simulation analysis. Then, by using the conventional oil‐

Deterioration Law of Mechanical Properties of Insulation Pressboard Under Multifield Coupled Ageing

High Voltage, EarlyView.
ABSTRACT Converter transformers can experience progressive deterioration of their oil–pressboard insulation under elevated temperature, combined AC–DC electrical stress and persistent mechanical vibration. This study investigates how mechanical vibration affects the mechanical properties of insulation pressboard and clarifies the associated microscopic

Russian wheat aphid: a model for genomic plasticity and a challenge to breeders

Insect Science, EarlyView.
Invasive foundress finds suitable habitat and reproduces through pathogenesis. Wingless females produce life offspring quickly, which leads to high population densities. High population densities result in competition, which may induce epigenetic changes and wing development for dispersal.

The plasticisation model of dye diffusion: Part 7

Coloration Technology, EarlyView.
Abstract Re‐evaluation using the Williams‐Landel‐Ferry equation, of exhaustion/fixation/adsorption data previously reported for four classes of anionic dye onto three different types of wool substrate, revealed that thermally activated dyeing/desorption behaviour is governed by the thermally regulated structural relaxation times of the respective water‐
