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.Technology: general issuesbicsscablationair arc plasmacircuit breakerCO2CuFcurrent interruptioncurrent zeroDC circuit breakerdouble breakfast switchgaseous breakdownhybrid dc circuit breakermagnetic fieldmagnetohydrodynamic simulationsoptical absorption spectroscopyoptical diagnosticsoptical emission spectroscopyplasma physicsprestrike characteristicsprestrike gapPTFESF6SF6 alternative gasessolid-state switchstatistical enlargement lawssurface roughnessSwan bandsswitching arcThomson actuatorvacuum arcvacuum arc commutationvacuum arc voltagevacuum circuit breakervacuum interrupterzero-crossingTechnology: general issuesUhrlandt Dirkedt1309865Uhrlandt DirkothBOOK9910557726503321Environmental Compatible Circuit Breaker Technologies3029678UNINA
