High Voltage, Volume 10, Issue 6, Page 1582-1592, December 2025.ABSTRACT The optical emission spectra (OES) reflect the presence of excited states in the gaseous discharge, which are directly linked to the decomposition characteristics of insulating gases. In this study, a pin/rod–plate discharge reactor driven by either a high‐voltage direct current (DC) generator or a pulsed generator was developed to establish ...

High Voltage, Volume 10, Issue 6, Page 1380-1389, December 2025.ABSTRACT Partial discharge (PD) is the indicator of the insulation defect in cables. However, the pulse current method, which is widely adopted in land cables, cannot obtain PD signals of high‐voltage direct current (HVDC) submarine cables due to attenuation and installation position.

Enhancing Corrosion Resistance of Copper for C4F7N Based Eco‐Friendly Gas‐Insulated Equipment
High Voltage, Volume 10, Issue 5, Page 1125-1134, October 2025.ABSTRACT Perfluoroisobutyronitrile (C4F7N) is recognised as the next‐generation dielectric medium for eco‐friendly gas‐insulated equipment (GIE). However, there is gas metal incompatibility in strong electromagnetic environments and environmentally friendly insulating gas atmospheres that endangers the operational safety and service life of GIE.
