Evaluation Methodology, Numerical Verification and Retrofilling Procedure for Power Transformers to Ensure K‐Class Flame Retardancy and Environmentally Friendly

High Voltage, EarlyView.
ABSTRACT With increasing demands for fire safety and environmental friendliness, retrofilling transformers with alternative insulating liquids has become a growing trend. However, retrofilling power transformers remains uncertain, as more residual mineral oil compromises K‐class flame retardancy, and its impact on environmental performance has yet to ...

Development of ± 550 kV DC GIS Basin Insulator

High Voltage, EarlyView.
ABSTRACT The basin insulator is a core component of the insulation system for ± 550 kV gas‐insulated switchgear (GIS). This paper, using a finite element method for multi‐physics simulations of electric–thermal coupling, determines a geometry suitable for the industrial production of ± 550 kV GIS basin insulators.

Review of Catenary Icing on High‐Speed Railways: Characteristics, Impact and Countermeasures

High Voltage, EarlyView.
ABSTRACT The pantograph–catenary system (PCS) is the only path for electrified railway trains to acquire energy. Catenary icing during winter is a common natural phenomenon, which usually leads to the deterioration of the current quality and severely affects the operational safety of trains.

Beyond the Law: A Qualitative Socio‐Ecological Study of Substance Use Treatment Barriers and Adaptations in Ghana

Journal of Psychiatric and Mental Health Nursing, EarlyView.
ABSTRACT Background Ghana's response to substance use has long been dominated by criminalisation, yet limited research has examined how this policy environment shapes addiction treatment delivery. This study explored the perspectives of mental health nurses providing care to people who use drugs (PWUDs) using a socio‐ecological framework.

Numerical Thermal‐Hydraulic Evaluation of an Integrated Direct‐Indirect Oil Cooling System for an Electric Motor Under Steady‐State Overload Conditions

Advanced Theory and Simulations, Volume 9, Issue 6, June 2026.
This study evaluates an integrated direct‐indirect oil cooling system for electric motor thermal management under steady‐state overload conditions. The results show that the combined cooling architecture improves heat removal from the winding, stator, and housing while balancing pressure drop penalties.
