Abstract

The paper deals with partial discharges caused by metallic contaminants in gas insulated transmission line (GITL) systems. Investigations were made on discharge characteristics in compressed sulphur hexafluoride (SF6) with free aluminum particles under AC voltage in a 70 mm/190 mm coaxial conductor system. Corona inception voltage, together with the time to first corona, are introduced as a possible diagnostic tool in estimating the size of the conducting particles present in the system.
