Development of ± 550 kV DC GIS Basin Insulator
High Voltage, EarlyView.ABSTRACT The basin insulator is a core component of the insulation system for ± 550 kV gas‐insulated switchgear (GIS). This paper, using a finite element method for multi‐physics simulations of electric–thermal coupling, determines a geometry suitable for the industrial production of ± 550 kV GIS basin insulators.

High Voltage, EarlyView.ABSTRACT The problem of gas–solid interface charge accumulation is an important reason for distorting the surface electric field and then inducing surface discharge. The temperature gradient distribution formed on the spacer during the operation of a gas‐insulated transmission line (GIL) will aggravate the surface charge accumulation, further ...

High Voltage, EarlyView.ABSTRACT To effectively suppress transient overvoltages in HVDC systems, the design and experimental validation of a multi‐module series controllable arrester are presented. The voltage‐limiting performance, series voltage equalisation capability, and robustness under fault conditions in high‐voltage scenarios require further research.
