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 ...

Influence of surface charges on alumina dielectrics on impulse flashover characteristics in vacuum [PDF]

, 2008
In this paper, we investigated the surface flashover characteristics under the existence of surface charge on alumina ceramic insulator in vacuum. We investigated the surface flashover voltage with varying the location and magnitude of surface charge. We

Experimental Study on Disintegration Characteristics of Water Droplets in Icicle‐Flat Plate Gap Beyond Critical Discharge Voltage

High Voltage, Volume 11, Issue 4, Page 1048-1057, August 2026.
ABSTRACT The disintegration behaviour of ice‐melting droplets aggravates the discharge risk of ice‐covered insulators and the disintegration characteristics of droplets at applied voltages exceeding the critical discharge voltage lack in‐depth study.

Particle traps constructed on the insulator of conductive slip rings for surface flashover mitigation under particle adhesion

AIP Advances
The generation of abrasive particles is an unavoidable consequence of sliding electrical contact wear in conductive slip rings (SRs). The adhesion of abrasive particles to the insulators may lead to a decrease in flashover voltage, posing a risk to ...
