IET Science, Measurement &Technology, Volume 20, Issue 1, January/December 2026.A series resistive‐capacitive divider for harmonic voltage measurement of gas‐insulated switchgear was studied. It can step down the voltage while amplifying the proportion of harmonics in the total sensed voltage, thereby increasing the significant figure for the measurement and enabling the accurate measurement of high‐order, low‐amplitude harmonics.

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.

High Voltage, Volume 10, Issue 4, Page 890-902, August 2025.Abstract Accurately identifying the location and type of internal defects in gas‐insulated switchgear (GIS) is a challenge. To address this challenge, this study proposes a novel method for the nondestructive detection of GIS internal defects. This method is based on x‐ray digital radiography (X‐DR) technology and an improved real‐time models for ...
