Research on Self‐Identification Technology of Zero‐Value Insulators in Distribution Lines Based on Electroluminescence Effect

High Voltage, EarlyView.
ABSTRACT To address the issue of low detection accuracy for zero‐value insulators in distribution lines, this study proposes a novel method for detecting these insulators based on the electroluminescence effect. Through theoretical analysis and experimentation, it was found that the luminescence intensity of ZnS:Cu electroluminescent material varies ...

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 ...

Anomaly Detection for Partial Discharge in Gas-Insulated Switchgears Using Autoencoder

IEEE Access, 2020
In this article, we propose a new anomaly detection method to detect the partial discharge in a gas-insulated switchgear. An autoencoder was used for anomaly detection and was modeled on the one-class classification problem.
