Investigation of the Evolution Mechanism and Multiphysics Coupling in Tree‐Contact Single‐Phase‐to‐Ground Fault

open access: yesHigh Voltage, EarlyView.
ABSTRACT Tree‐contact single‐phase‐to‐ground fault (TSF) is a common and hazardous type of failure in distribution networks. TSF is likely to occur when overhead conductors contact moist tree branches, potentially leading to insulation breakdown, posing serious threats to grid safety.

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.

Advanced Sensing Materials and Their Applications for Power Sensors

open access: yesHigh Voltage, EarlyView.
ABSTRACT The construction of new‐generation power systems imposes stringent requirements on the safety and reliability of critical equipment, making accurate state perception essential for grid security and digital transformation. Sensing materials fundamentally determine sensor performance in terms of sensitivity, bandwidth, environmental adaptability

Study on Raindrop Dynamic Behaviour and Its Impact on Insulator Flashover Characteristics Under Airflow Synergy

open access: yesHigh Voltage, EarlyView.
ABSTRACT The synergistic effect of airflow on rainfall behaviour significantly impacts the flashover probability of insulators. This study combines experiments and simulations to investigate the influence of raindrop dynamic behaviour, shed structures and rainfall conditions on flashover characteristics under airflow conditions.

Recommendations to Reform the National Electricity Market (NEM)

open access: yesAustralian Journal of Agricultural and Resource Economics, EarlyView.
ABSTRACT Australia's National Electricity Market (NEM) was established in the late 1990s. The market is an energy only gross pool with zonal (state‐based) pricing. Over the past 15 years, the system has undergone a profound transformation as large coal‐fired power stations have retired and substantial volumes of large‐scale and embedded behind the ...

A Crisis of Representation: Reflections on John Boswell, How Citizens Encounter the Democratic State

open access: yesThe Political Quarterly, EarlyView.
Abstract In this symposium contribution, we subject John Boswell's How Citizens Encounter the Democratic State to the scrutiny warranted by its contribution. While the book offers a rich categorisation of the myriad forms of mundane agency one can observe in the underbelly of the democratic state, we seek to extend the argument by situating it in some ...

Patient Safety and Organisational Accountability: Reassessing Criminal Liability Frameworks in Healthcare

open access: yesThe Modern Law Review, EarlyView.
Serious harm in healthcare often results from systemic failures, yet criminal accountability remains largely addressed through homicide law, gross negligence manslaughter and health‐and‐safety offences, frameworks that emphasise individual culpability and are ill‐suited to addressing organisational failings.
