Abstract: An ignition apparatus for a spark gap arrangement containing at least a first and a second ignition capacitor for voltage division of a voltage between a first and a second electrode of the spark gap arrangement. A first trigger spark gap is arranged in a first parallel branch with respect to the first ignition capacitor, and a second trigger spark gap is arranged in a second parallel branch with respect to the second ignition capacitor. A first ignition resistor is disposed in the first parallel branch, wherein a first potential point between the first ignition resistor and the first trigger spark gap is connected to an ignition electrode of the second trigger spark gap. Furthermore, a spark gap arrangement containing the ignition apparatus, an arrangement containing a high-voltage device and the spark gap arrangement for protecting the high-voltage device, and a method for igniting the spark gap arrangement are disclosed.

Abstract: In order to provide a spark gap configuration for overvoltage protection, the spark gap configuration has electrodes that face each other and exhibit a short deionization time. The electrodes have, on at least a portion thereof, a current-path bounding device for forcing a desired current path in the electrodes themselves resulting in improved spark behavior.
