<p>A gas insulated switching device including a series of pressure containers 1 and 4 mutually connected, in which a conductor 2 is positioned in an inside center, and an insulating and arc-extinguishing gas is filled in a space around the conductor 2, and a current transformer fabricated by Rogowskii coils for detecting a current passing through the conductor 2, the current transformer is attached to flanges of the pressure containers 1 and 4 via a metallic adaptor 5, wherein the current transformer is accommodated in a groove formed toward an inside of the metallic adaptor 5 and uses the metallic adaptor 5 to obtain an earth potential, whereby the gas insulated switching device having the current transformer with high accuracy can be miniaturized. <IMAGE></p> |
