ABSTRACT:
A metal ring adjacent the support insulator of a gas-insulated bus lines the interior of the outer grounded housing. The ring is formed to define at least a portion of a turn around the central bus so that, in the event of an arc from the central bus to the outer grounded housing, the arc root will fall on the interior of the metal ring and the arc current will create a magnetic field which will cause the arc root to rotate around the interior of the metal ring.
