ABSTRACT:
A gas insulated transmission line includes an elongated outer sheath at ground potential, an inner conductor disposed within the outer sheath at high electrical potential, an insulating gas electrically insulating the inner conductor from the outer sheath, and an insulating spacer insulatably supporting the inner conductor within the outer sheath. An electrically conducting particle-trapping ring is disposed within, and spaced apart form, the outer sheath between the spacer and the outer sheath. The ring and the outer sheath form a low field region therebetween for the entrapment of conducting particles therein. Means are included for electrically connecting the particle-trapping ring to the outer sheath.
