Recent results of experimental and theoretical investigations on current interruption processes are presented with a focus on SF 6 high voltage circuit breakers. Various aspects of thermal interruption at the zero crossing of the current are shown, including the scatter and the distribution of arc voltage shortly before CZ and the role of turbulence. The thermal interruption capability of air and CO 2 are compared to that of SF 6 . Investigations on the dielectric recovery are shown for SF 6 and CO 2 . The breakdown voltage during the dielectric recovery can be described by simple streamer and leader inception models. (© 2014 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
