A novel sight for understanding surface charging phenomena on downsized HVDC GIL spacers with non-uniform conductivity

, 2020
Surface charging phenomena on DC GIL spacers is a complicated process affected by lots of factors, among which surface conductivity is an important dielectrics parameter. In this study, experimental and theoretical research are carried out to investigate

A novel nonlinear conductive ZnO micro-varistor/epoxy resin composite film for metallic particle deactivation in DC GIL

IEEE transactions on dielectrics and electrical insulation, 2020
Enclosure coating is a promising technique of metallic particle contamination deactivation in DC gas-insulated transmission lines (DC GIL). However, the conventional insulation film cannot inhibit partial discharge (PD) at triple junction around the ...

Improved Method for Acoustic Identification of Free Conductive Particle Defects in GIL

IEEE Transactions on Power Delivery, 2019
The presence of free conductive particles in gas-insulated transmission lines (GIL) is the most significant threat to their insulation. The non-invasive identification of free conductive particle defects in GILs is extremely challenging.
