Development of automatic identification method for GIS PD (Partial Discharge) defects diagnosis

In this paper, an overview of a new GIS (gas insulated switchgear) PD (partial discharge) diagnostic algorithm for both single-defects and multi-defects in HiPDS-G (Hyundai intelligent preventive diagnostic system for GIS) developed by HHI(Hyundai Heavy Industries Co., Ltd) is given. The work includes PD defects data acquisition and analysis, ANN (artificial neural network) modeling as an automatic identification method and application for PD defects diagnosis. And the agreement rate analysis through the application of the developed algorithm for PD defects diagnosis is performed.
