摘要： An electrical assembly for use in an electrical system comprising a DC path which includes a DC power transmission medium; and a current commutation device 212, which includes a switching element 214, which may be an IGBT or other kind of electronic switch, and an energy absorbing element 216, which may be a linear or non-linear resistor. The switching element 214 is arranged to permit a current flowing through the DC path to flow through the switching element 214 and at the same time bypass the energy absorbing element 216. The electrical assembly further includes a control unit 220 programmed to selectively control the switching of the switching element 214, for example in response to a fault, to commutate the current directly from the switching element 214 to the energy absorbing element 216 in order to increase the resultant voltage drop caused by the flow of direct current through the DC path and oppose the flow of the current through the DC path.

The second current flow path (30) includes a first current flow control element (34) that is configured to operate in a first mode in which it minimises the flow of current through the second current flow path (30) when the first current flow path (28) is open and thereby minimises the flow of current between the AC terminal (20) and ground (26) when the first current flow path (28) is open. The electrical assembly (10) additionally includes a control unit (42) operatively connected to the switching element (32), the control unit (42) being configured to operate the switching element (32) to maintain open the first current flow path (28) following an occurrence of a DC network fault.
