SF6 Gas Analysis Technique and its Application for Evaluation of Internal Conditions in SF6 Gas Equipment

A number of standards have been established on the gas analysis of SF6 gas equipment. Throughout the past 15 year record of manufacturing SF6 gas equipment, gas analysis has been made by the authors on a number of apparatus in operation, as well as on simulation tests of various conditions. The results showed that gas analysis is effective in the diagnosis of SF6 gas equipment and that a gas checking type detector is quite suitable for field tests.
