Investigation of Partial Discharge in Solid Dielectric under DC Voltage
, 2014 A partial discharge, or PD, is defined as an electrical discharge that is localized within only a part of the insulation between two separated conductors. Recent research on PD mainly focuses on the study of PD characteristics under AC voltage.

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 ...
