Investigation of the Simplified Equivalent Circuit Model of the Post‐Arc Sheath Stage in DC Vacuum Circuit Breakers

open access: yesHigh Voltage, EarlyView.
ABSTRACT This paper presents a simplified equivalent circuit model (ECM) for the post‐arc sheath stage in DC vacuum circuit breakers and outlines the method for calculating circuit parameters using the particle‐in‐cell Monte Carlo collision (PIC‐MCC) method. The post‐arc sheath is modelled as a parallel combination of a variable resistor and a variable

Dynamic Behaviour of Bubbles in Oil Under Electrothermal Ageing

open access: yesHigh Voltage, EarlyView.
ABSTRACT During long‐term operation of converter transformers, the internal oil–pressboard insulation undergoes irreversible degradation. Partial discharge in the weakened insulation will cause the formation of a large number of bubbles in the insulating oil.

Anisotropy in Dry‐Type Valve‐Side Bushings of Converter Transformer: Phenomena and Effects

open access: yesHigh Voltage, EarlyView.
ABSTRACT The safe and stable working of dry‐type valve‐side bushings, important components of converter transformers, is essential. In recent years, poor design has led to several core breakdown, flashover and cracking failures. The bushing cores, composed of crepe paper and aluminium foil, exhibit significant anisotropic physical properties due to its

Centralised by Design: Anglocentric Constitutionalism, Accountability and the Failure of English Devolution

open access: yesThe Political Quarterly, Volume 96, Issue 1, Page 189-198, January/March 2025.
Abstract The Labour manifesto in this year's election implied a radical restructuring of the UK state, the way in which England is governed and in relations across the United Kingdom. The aim of making English devolution the ‘default option’ is set against fifty years of unsuccessful and partial devolution initiatives which have failed to reverse the ...

Including AKIS in the 2023 CAP Strategic Plans: What Difference has it Made? Intégration des systèmes de connaissances et d’innovation agricoles (SCIA) dans les plans stratégiques de la PAC pour 2023 : Qu’est‐ce que ça a changé ? Die Einbeziehung von AKIS in die strategischen Pläne der GAP für 2023: Was hat sich dadurch verändert?

open access: yesEuroChoices, EarlyView.
Summary In 2021, for the first time, the EU Member States were required to include Agricultural Knowledge and Innovation Systems (AKIS) in their Common Agricultural Policy (CAP) Strategic Plans (2023–2027). We present the findings of empirical research into how this requirement has influenced the development of national AKIS.

The End of EU Rural Development Policy As We Know It? La fin de la politique de développement rural de l'Union européenne telle que nous la connaissons? Das Ende der EU‐Politik, zur Entwicklung des ländlichen Raums, wie wir sie kennen?

open access: yesEuroChoices, EarlyView.
Summary The European Commission's proposals for the EU funding period 2028–2034 promise paradigmatic change. A single National and Regional Partnership Fund would merge several currently autonomous funds, including the Common Agricultural Policy (CAP).
