Abstract: A spark gap for surge diverters is composed of a plurality of plates of insulating material stacked one on the other with spaces there between. Electrodes are carried on each face of the plates. The electrodes have parts connected to each other by attachment members passing through the plates. The electrodes at each space have vertically aligned parts forming a spark gap and the parts deviating from vertical alignment and forming a running-out path which becomes substantially parallel to the plane of the plates.

Abstract: A spark gap is formed between two discs of insulating material resistant to the arc and with a space therebetween. Two outer electrodes extend through the space between the discs from one side almost to the other periphery. These electrodes are insulated through most of their length on their outer faces. An intermediate electrode is arranged on the inner wall of the space facing the two outer electrodes and extending angularly a substantial distance around such inside wall. This electrode has a protrusion opposite the space between the outer electrode. The arcs are magnetically drawn into the portions of the space between the electrodes remote from the intermediate electrode and are there extinguished.

Abstract: A reigniting spark gap for surge diverters with magnetic blowing has electrodes arranged on an insulating base. Each electrode has a spark gap part arranged in an extinguishing chamber and the spark gap parts of the electrodes diverge from an ignition point and the surfaces of the spark gap parts face each other and form running-out paths for the foot points of the arc arising between the electrodes. At least one of the two surfaces of the spark gap parts facing away from each other forms a return path for one foot point of an arc. The return path has an end point substantially opposite the ignition point. A channel connects the running-out path and the return path and forms a through-flow channel for ionized gas from the return path to the running-out path.

Abstract: An overvoltage protection device consists of a number of parallel connected columns containing nonlinear resistance stacks between upper and lower spark gap stacks. The spark gap stacks provide arc extension by magnetic effect. Cross-impedances are arranged between the columns for transferring ignition pulses. The spark gaps, nonlinear resistors and connecting members for the cross-impedances are so dimensioned and arranged that the impedance increase of a column after ignition in comparison with the impedance increase of one or more subsequent ignited columns is so great that the current through the first column is less than a value corresponding to its lowest current carrying voltage. The cross-impedances may be connected between the bottom of an upper spark gap stack and the top of a lower spark gap stack.
