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.

Signal Extraction and Clustering of Partial Discharge in Motor Insulation Using Temporal Correlation‐Based Clustering

open access: yesHigh Voltage, EarlyView.
ABSTRACT As one of the important links in energy transition and global energy interconnection, electric vehicles (EVs) are becoming increasingly major research topics in the field of energy. Partial discharge (PD) identification under repetitive impulsive voltages plays a pivotal role in evaluating the health of electric vehicle (EV) motor insulation ...

Come Up, Come in with Streamers! [PDF]

open access: yes, 1917
Come up, come in with streamers! Come in with boughs of may! Come up and thump the sexton, And carry the clerk away. Now skip like rams, ye mountains, Ye little hills like sheep! Come up and wake the people That parson puts to sleep.

Study on the Coupled Effects of High‐Speed Airflow and Charged Sand on Power‐Frequency Discharge Characteristics of Conductor–Tower Gaps in Strong Wind–Sand Environments

open access: yesHigh Voltage, EarlyView.
ABSTRACT Strong wind–sand weather in Xinjiang threatens power grid safety by increasing transmission line tripping risks. Existing studies focus on sand polarization but neglect the coupled influence of high‐speed airflow and charged sand on gap discharge characteristics.

Research on the Audible Noise Spectrum Characteristics of Typical AC Bundled Conductors in High‐Altitude Areas at 4300 m

open access: yesHigh Voltage, EarlyView.
ABSTRACT The low pressure in high‐altitude areas exacerbates the issue of audible noise (AN) caused by intense corona discharge on the conductor surface. This problem is a critical factor in the structural design and conductor selection for extra‐high‐voltage and ultrahigh‐voltage (UHV) AC transmission lines.

Investigation of the Partial Discharge Inception and Flashover With IEC‐Based Comparative Tracking Index Electrodes and Comparison With Homogeneous and Inhomogeneous Electric Fields at Varying Pressures for Aerospace Applications

open access: yesHigh Voltage, EarlyView.
ABSTRACT For designing aeronautical components, the creepage distance is usually estimated by considering the pollution level and the dielectric material group as defined by the standard IEC 60664‐1. The material group is expressed by the comparative tracking index (CTI) performed at atmospheric pressure following the standard IEC 60112.

When Thriving for More Collapses the System: The Academic Reproduction of Uncaring Structures

open access: yesBritish Journal of Management, EarlyView.
Abstract This essay argues that the widening gap between aspirational aims and visionary orientations and the prevailing practices in neoliberal academia stems from deeper, historically rooted, market‐based logics shaping our institutions, increasingly governed by economic values and academic subjectivities therein.

The 2024 General Election and the Rise of Reform UK

open access: yesThe Political Quarterly, Volume 96, Issue 1, Page 91-101, January/March 2025.
Abstract This article examines the social base of support for Reform UK. Did Nigel Farage's new party depend on the same types of ‘left behind’ voters who had previously backed UKIP? Do the results of the 2024 election suggest a hardening of the social divides that underpinned the rise of UKIP? Or has Britain's Eurosceptic and anti‐immigration movement
