Abstract :
This paper describes a single-tank power circuit breaker utilizing sulfurhexafluoride (SF6) gas as the interrupting medium. A complete description of the breaker is given. Test procedures used in life testing, voltage testing, and interrupting tests are described. Oscillograms of tests and tabulated test data are given which demonstrate its assigned rating of 69-kv 5,000-mva (megavolt-ampere) 5-cycle interrupting time.
