Abstract

In a current limiter for limiting currents in case of a fault including an additional device comprising an additional electric valve connected in series and being conductive in the same direction as the associated main valve, two series-connected valve branches arranged in opposition bypass two series connected current limiting inductors and both additional valves are bypassed by a similar passively complex connection for limiting current in the case of a fault, wherein the current limiter is not noticeable during normal operation, but, in the event of a fault, effectively limits the short circuit to a predetermined extent.
