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 ...

High Voltage, Volume 10, Issue 4, Page 831-844, August 2025.Abstract Mechanical vibration defect is the key factor leading to sudden failure of gas‐insulated switchgear (GIS) equipment. It is important to realise effective prediction of the mechanical vibration state development trend of GIS equipment in order to improve its active safety protection level.

A novel GIS breakdown location method based on natural frequency of transient voltage
High Voltage, Volume 10, Issue 4, Page 856-875, August 2025.Abstract During on‐site withstand voltage tests of gas‐insulated switchgears (GIS), once a breakdown occurs, it is hard to locate the breakdown position due to the intricate branch structures and minimal breakdown energy. The existing methods may require the placement of a large number of sensors with unsatisfactory accuracy, which adversely affects ...
