A series spark gap (5a,5b) comprising at least three partial spark gaps is provided. In a continuous operation mode a supply voltage (Ucap) acting over the partial spark gaps is divided by first voltage dividing means (11a-11d). During triggering more than half of the partial spark gaps are bypassed by using bypass means (12,14) such that more than half of the supply voltage acts over the partial spark gaps that are not bypassed, whereby the partial spark gap or the partial spark gaps that are not bypassed ignite. The voltage acting over the bypassed partial spark gaps is divided asymmetrically using the bypass means whereby the bypassed partial spark gaps ignite sequentially in the order determined by the asymmetric voltage division. |
