2014/11/10Therefore, this limit does not mean that higher SF6 concentrations pose any toxic hazard. According to Clause 7.1 of IEC 60480: "In principle, a mixture of 20% of oxygen and 80% SF6 can be inhaled without adverse effect. Concentrations above 20% would cause suffocation due to lack of oxygen.

Operating PrincipleBrief HistoryDesign FeaturesGenerator Circuit BreakersHigh Power TestingIssues Related to SF6 Circuit BreakersComparison with Other TypesCurrent interruption in a high voltage circuit breaker is obtained by separating two contacts in a medium, such as sulfur hexafluoride (SF6), having excellent dielectricand arc quenching properties. After contact separation, current is carried through an arc and is interrupted when this arc is cooled by a gas blast of sufficient intensity. SF6 gas is electronegativeand has a strong tendency to absorb free electrons. The contacts of the breaker are opened in a high pressure flow of sulfur hexafluoride gas, and an arc is struck between them. The gas captu…See more on en.wikipedia.orgEstimated Reading Time: 12 minsTesting And Commissioning Of Substations Up To 500KV npcetc.vn/en/activities/Testing And Commissioning Of...OVERVIEW OF COMPANY CAPACITY Over time the formation and development, NPCETC has been trusted by the units inside and outside the power industry to do the testing of all 110kV, 220kV, 500kV substations and periodic testing of all 110kV substations in northern area.
