Abstract

A control system for at least one vacuum interrupter gap in a high-voltage switching device includes at least one non-reactive control resistor disposed in parallel with the vacuum interrupter. The non-reactive control resistor merges concentrically onto the vacuum interrupter chamber and is mechanically and electrically coupled thereto.
