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.
