Computational Chemistry‐Driven Advances in Eco‐Friendly Insulation Gas Research: Multi‐Dimensional Prediction, Synergistic Screening, Stability Evaluation and Molecular Design

open access: yesHigh Voltage, EarlyView.
ABSTRACT Sulphur hexafluoride has become a priority substance for greenhouse gas mitigation in electric systems. An ideal substitute should simultaneously satisfy requirements for dielectric strength, boiling point, global warming potential and chemical stability; however, these metrics are deeply coupled and mutually constraining at the molecular ...

DETERMINATION OF THE LEVEL OF OVERVOLTAGE IN THE SECONDARY CIRCUITS OF SUBSTATIONS WHEN LIGHTNING IMPULSE VOLTAGE IS DISTRIBUTED IN HIGH-VOLTAGE BUSES

open access: yesИзвестия высших учебных заведений и энергетических объединенний СНГ: Энергетика, 2017
Lightning voltage impulse due to the waves of storm surge rolling out the high voltage line to a substation causes current to flow in the buses that, due to magnetic effect, induces overvoltage in the secondary circuit.

The Constellation: A Reappraisal of Walter Benjamin's Influence on Theodor W. Adorno

open access: yesConstellations, EarlyView.
ABSTRACT In the 1920s and 1930s, Walter Benjamin and Theodor W. Adorno both sought to develop a notion of Darstellung—of philosophical presentation or representation—that could provide an alternative to the classically idealist tendency to subsume objects under abstract concepts.

Lightning Protection Technology for Overhead Insulated Lines of 10kV Distribution Network Based on Linear Least Square Positioning Method

open access: yesJournal of Applied Science and Engineering
The calculation of the series gap distance of the lightning protection device in the 10 kV distribution network is rough, and the positioning error of the lightning strike point may be large, which affects the stability of electricity consumption ...

The Political Ecology of the ‘New’ Feminism in Late‐1990s Britain

open access: yesGender &History, EarlyView.
ABSTRACT The 1990s were a vexed time for feminists in Britain. Cultural commentators declared that feminism's key battles had been won, and that given women's ascendency across various political and cultural barometers of success, the country was entering a newly ‘postfeminist’ era.
