Abstract
A DC circuit breaker arrangement for interrupting a direct current on a line, includes: n DC circuit breakers connected in parallel, where n>2, which parallel connection of DC circuit breakers is connected in series with the line, the direct current of the line being divided between the n DC circuit breakers, and n reactors, each reactor being connected to one of the DC circuit breakers, for preserving the current division during current interruption. A method for interrupting or commutating a direct current on a transmission line or in a HVDC circuit is also provided.
