Abstract
The invention relates to an HVDC breaker () comprising at least two individually controllable HVDC breaker sections () connected in series, wherein the HVDC breaker is arranged in a manner so that the number of HVDC breaker sections tripped upon tripping of the HVDC breaker depends on the operational event in response to which the tripping occurs. The invention further relates to a control apparatus () for controlling the HVDC breaker, as well as to a method of breaking an HVDC line. The method comprises receiving () a system status signal indicative of an operational event requiring the breaking of the HVDC line, and determining () the number of HVDC breaker sections required for the breaking.
