Vulnerability assessment of high-voltage direct current transmission systems to cyberattacks

Security and Safety
High-voltage direct current (HVDC) transmission systems demonstrate significant advantages in long-distance and high-capacity power transmission. Voltage-source converter-based HVDC (VSC-HVDC), with its flexible power flow control and independent active ...

Dynamic Behaviour of Bubbles in Oil Under Electrothermal Ageing

High Voltage, Volume 11, Issue 4, Page 975-986, August 2026.
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.

Development of ± 550 kV DC GIS Basin Insulator

High Voltage, Volume 11, Issue 4, Page 1068-1077, August 2026.
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.

A Thermal‐Dependent Conductivity Coating for Surface Charge and Electric Field Mitigation Under Electrothermal Coupling Field

High Voltage, Volume 11, Issue 4, Page 928-938, August 2026.
ABSTRACT The problem of gas–solid interface charge accumulation is an important reason for distorting the surface electric field and then inducing surface discharge. The temperature gradient distribution formed on the spacer during the operation of a gas‐insulated transmission line (GIL) will aggravate the surface charge accumulation, further ...
