Comparative Evaluation of Optimisation Algorithms for Artificial Neural Network‐Based Classification of Partial Discharge Defects in Generator Stator Windings

Engineering Reports, Volume 8, Issue 6, June 2026.
This study presents a framework for Partial Discharge (PD) recognition. The process involves generating PD signals using IDS, followed by data augmentation and denoising. Key features are extracted to train an Artificial Neural Network (ANN) model, enabling the accurate classification and identification of specific PD patterns in electrical insulation ...

Research on Power Frequency Insulation Properties and Configurations of CF3SO2F Gas Mixture for Industrial Applications

High Voltage, Volume 11, Issue 2, Page 556-563, April 2026.
ABSTRACT The breakdown characteristics of the novel eco‐friendly insulating gas CF3SO2F are fundamental to the design of gas‐insulated equipment. In this paper, the gas mixture parameters for CF3SO2F were optimised for different ambient temperatures in order to ascertain the insulation performance and liquefaction temperature constraints.

Highly Selective Adsorption of Fluorinated Gases by Porous Organic Cages – Effects of Fluorinated Side‐Chains

Advanced Materials, Volume 38, Issue 7, 2 February 2026.
A systematic study of a series of porous organic cages with perfluorinated alkyl side‐chains of different lengths is presented. The structure‐property relationship of the various cages on gas sorption of highly potent greenhouse gases, such as perfluorocarbons (PFCs), sulfur hexafluoride (SF6), and nitrogen trifluoride (NF3) is investigated.

Spectral Characteristics and Evolution Mechanism of Silicon Rubber Surface Discharge Under Thermal Ageing Condition

High Voltage, Volume 11, Issue 1, Page 192-200, February 2026.
ABSTRACT Surface discharge is a typical fault type in electric power equipment. High temperature in long‐term operation can easily lead to ageing of materials, resulting in changes in surface characteristics and surface discharge faults. In this paper, a method of surface discharge identification of silicon rubber (SiR) based on spectral detection ...

Nondestructive Measurement of Residual Stress on Epoxy Insulators Using Thermoelastic Method

High Voltage, Volume 11, Issue 1, Page 274-283, February 2026.
ABSTRACT Residual stress is inevitable in epoxy insulators, which easily leads to small cracks and even insulation breakdown during the operation of gas‐insulated transmission line (GIL)/gas‐insulated switchgear (GIS). This study proposes a nondestructive method to measure the residual stress on epoxy insulators using thermoelastic effects.
