Abstract

A spark-gap arrangement encapsulated in a pressure-proof housing, for diverting harmful disturbances due to overvoltage, including at least two electrodes disposed substantially opposite one another in a housing that is conductive or provided with a conductive coating, between which a discharge space is formed and which are insulated from the housing. In accordance with the spark-gap arrangement a trigger voltage to form a subsidiary spark gap in the discharge space can be applied directly by the conductive housing, so that by the subsidiary spark gap the main spark gap between the main electrodes can be ignited.
