Abstract Gas‐insulated switchgear (GIS) plays a critical role in ensuring the reliability of power systems, but partial discharge (PD) is a primary cause of failures within GIS equipment. Traditional PD diagnostic methods rely heavily on laboratory data, which differ significantly from that under the complex conditions of field data, leading to a ...
