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 i…See more on en.wikipedia.orgEstimated Reading Time: 12 minsMajor components you can spot while looking at HV/EHV GIS (Gas … electrical engineering portal/gis gas insulated switchgear components2019/9/18The circuit breaker in a gas insulated system is metal clad and utilises SF6 gas, both for insulation and fault interruption. The SF6 gas pressure in a circuit breaker is around 0.65 MPa . The circuit breaker is directly connected to either current transformers or the isolators in gas.

The plant safety of SF 6 gas insulated switchgear is reduced significantly through low concentrations of decomposition products. These decomposition products arise during operation through arcing in moist or impure SF 6 gas. In order to detect even the smallest leakages or to warn ahead of gas emissions, we have a range of high quality gas detectors and emission monitors.
