Title: Method of testing gas insulated systems for the presence of conducting particles utilizing a gas mixture of nitrogen and sulfur hexafluoride

Abstract

A method of testing a gas insulated system for the presence of conducting particles is presented. The method includes inserting a gaseous mixture comprising about 98 vol % nitrogen and about 2 vol % sulfur hexafluoride into the gas insulated system at a pressure greater than 60 lb psig, and then applying a test voltage to the system. If particles are present within the system, the gaseous mixture will break down, providing an indicator of the presence of the particles.
