Abstract (en)

[origin: WO2017207328A1] The invention relates to an over-voltage protection system for a single or multi-phase current supply grid, consisting of at least two triggered spark gaps connected in parallel, wherein the spark gaps have two primary electrodes and one ignition electrode, which is is connected to one of the primary electrodes by means of a control. According to the invention, for a selective, on-demand connecting of an another of the parallel-connected spark gaps, the ignition electrodes of the spark gaps are connected by means of a voltage-independent switching element, such that the additional spark gap ignites when the response value from the series connection consisting of the voltage-dependent switching element and the ignition gap of the ignition electrode of the additional spark gap is reached.
