Description
Summary:This paper discusses those tests believed necessary in both factory and field to assure safe and reliable performance in a sulphur hexafluoride (SF6) gas insulated system. Design tests on prototype components, routine factory production tests and field tests immediately prior to placing the system in service are discussed. Primary emphasis is given to dielectric testing, because of the importance of dielectric considerations to system integrity. Actual test experience on five installations now in service is discussed.
