Dark current characteristics and their correlation with surface charge accumulation on insulators in clean-air HVDC GIS
Surface charge accumulation on insulators is a critical concern for high-voltage direct current gas-insulated switchgear (HVDC GIS), as it distorts the electric field at the gas–solid interface and further initiates partial discharge or surface flashover. As an environmentally friendly alternative insulating medium, cl...
