Electric arcs in gases or a vacuum are the key component in the technology at present and will play a key role also in future concepts, e.g., for hybrid and fast switching required for high-voltage direct-current (HVDC) transmission systems. In addition, the replacement of the environmentally harmful SF6 in gas breakers and gas-insulated switchgear is an actual issue. This Special Issue comprises eight peer-reviewed papers, which address recent studies of switching arcs and electrical insulation at high and medium voltage. Three papers consider issues of the replacement of the environmentally harmful SF6 by CO2 in high-voltage gas circuit breakers. One paper deals with fast switching in air with relevance for hybrid fault current limiters and hybrid HVDC interrupters. The other four papers illustrate actual research on vacuum current breakers as an additional option for environmentally compatible switchgear; fundamental studies of the vacuum arc ignition, as well as concepts for the use of vacuum arcs for DC interruption. 606 $aTechnology: general issues$2bicssc 610 $avacuum circuit breaker 610 $adouble break 610 $aprestrike characteristics 610 $avacuum interrupter 610 $aprestrike gap 610 $agaseous breakdown 610 $aSF6 610 $aCO2 610 $asurface roughness 610 $astatistical enlargement laws 610 $avacuum arc 610 $aDC circuit breaker 610 $acurrent interruption 610 $amagnetic field 610 $aplasma physics 610 $azero-crossing 610 $acircuit breaker 610 $aswitching arc 610 $aoptical emission spectroscopy 610 $aablation 610 $acurrent zero 610 $aSF6 alternative gases 610 $aPTFE 610 $aoptical absorption spectroscopy 610 $aSwan bands 610 $aCuF 610 $ahybrid dc circuit breaker 610 $avacuum arc commutation 610 $asolid-state switch 610 $avacuum arc voltage 610 $aair arc plasma 610 $aThomson actuator 610 $amagnetohydrodynamic simulations 610 $afast switch 610 $aoptical diagnostics 615 7$aTechnology: general issues 700 $aUhrlandt$b Dirk$4edt$01309865 702 $aUhrlandt$b Dirk$4oth 906 $aBOOK 912 $a9910557726503321 996 $aEnvironmental Compatible Circuit Breaker Technologies$93029678 997 $aUNINA
