Research on the Online Diagnosis Method for Heating Types of Composite Insulator

High Voltage, Volume 11, Issue 4, Page 1040-1047, August 2026.
ABSTRACT In response to the current challenge of accurately determining the specific heating status of composite insulators with localised temperature rise using infrared detection technology, this paper proposes a novel diagnostic method. This method involves applying a disturbance to monitor the surface temperature rise data of composite insulators ...

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 ...
