Investigating Breathing Dynamics of a 110 kV Oil‐Immersed Transformer Using Thermal‐Fluid‐Structure Interaction Modelling

open access: yesHigh Voltage, EarlyView.
ABSTRACT The breathing system of an oil‐immersed transformer is of vital importance for maintaining equilibrium between internal and external pressures, with any malfunction potentially disrupting the transformer's stable operation. This study develops a thermal–fluid–structure interaction (TFSI) model to simulate the breathing phenomenon in a 110 kV ...

Development of ± 550 kV DC GIS Basin Insulator

open access: yesHigh 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.

800 kV Fast Circuit Breaker: Mechanical Coupling Modelling, Buffer Design and Development

open access: yesHigh Voltage, EarlyView.
ABSTRACT The 800 kV fast circuit breaker (CB) used in ultra‐high voltage (UHV) converter transformer can reduce the total breaking time to 25 ms. It significantly improves the action speed and breaking capacity of the CB, with promising broad application prospects.

An Overview of High‐Temperature Superconducting Cables in DC Systems: Unlocking Potential for High‐Voltage DC Networks

open access: yesHigh Voltage, EarlyView.
ABSTRACT This paper provides an overview of high‐temperature superconducting (HTS) cables in DC systems, with a focus on their deployment in high‐voltage DC (HVDC) networks. The assessment of HTS cable properties—such as extremely low electrical resistance, high current‐carrying capacity and a compact geometry—and their comparison with those of ...

The Gender of Fossil Fuels: Oil and Domestic Perils in Mandate Palestine

open access: yesGender &History, EarlyView.
ABSTRACT This article explores the gender dynamics behind the rise of kerosene – an oil derivative – as the main domestic fuel in Mandate Palestine. It argues that these dynamics were constitutive in determining who began to use oil, where and for what purposes, in turn demonstrating that women in Palestine were the promoters and targets of a campaign ...
