Abstract
A gas-insulated switchgear apparatus includes a center conductor, a current transformersurrounding the center conductor, an electric field shield, and a metallic vessel. The electric field shieldis located between the center conductorand the current transformerand surrounds the center conductor. The current transformerand the electric field shieldconstitute a tubular part that outputs a signal representing an electric physical quantity. The metallic vesselis filled with an insulating gas. The tubular part has an openingformed therein. In a posture in which the center axis of the tubular part about which the tubular part surrounds the center conductoris substantially horizontal, the openingis located in a surface of the tubular part, which surface is included in a lower portion of the tubular part and faces the center conductor
