Under DC voltage, the interface charge of the spacer in gas-insulated metal-enclosed transmission lines (GIL) and gas-insulated metal-enclosed switchgear (GIS) is prone to accumulate, and the charge is an important factor to induce surface flashover.

Multidimensional Functionally Graded Materials (ε/σ-MFGM) for HVDC GIL/GIS Spacers
IEEE transactions on dielectrics and electrical insulation, 2022This study discusses the multidimensional functionally graded materials (MFGMs) for spacers in high voltage direct current gas-insulated transmission lines and switchgears (HVDC GILs/GISs). The effects of surface conductance graded materials ( $\sigma $ -

SAFE-GIL: SAFEty Guided Imitation Learning for Robotic Systems
IEEE International Conference on Robotics and AutomationBehavior cloning (BC) is a widely used approach in imitation learning where a robot learns a control policy by observing an expert supervisor. However the learned policy can make errors and might lead to safety violations which limits their utility in ...
