IEEJ Transactions on Power and Energy, 1993 AbstractGas‐insulated switchgears (GIS) are important equipment in electric‐supply stations where advanced techniques for safety and maintenance are required. As a result, a system is being developed that can automatically monitor and diagnose a GIS in service.This article focuses on some problems concerning insulating functions of GIS to discuss a ...

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.
