Abstract
A DC circuit breaker arrangement for interrupting a current on a transmission line or in a HVDC circuit is provided. The DC circuit breaker arrangement comprises a first DC breaker and a second DC breaker, identical to the first DC breaker. The second DC breaker is connected in parallel with the first DC breaker on the transmission line or in the HVDC circuit and the current is divided between the first and the second DC breakers. By means of the invention, a DC circuit breaker arrangement is provided able to handle very high currents. The invention also relates to a corresponding method.
