Abstract: The invention comprises a system for electrical power transmission and distribution to a plurality of subsea loads (4a-d). The system includes a long high voltage DC transmission cable (12) on the power side connected to two or more power supplies (20a-c) each comprising a DC/AC converter (2a-c) connected in series. The DC/AC converters (2a-c) are each connected to a transformer (3a-c) connected to supply one or more subsea power loads (4a-d). The power supplies are arranged with a bypass switch (1a-c) on the power side. The transformers (3a-c) may be of a split core type with a primary winding in a first HV enclosure (5) inductively connected to at least one secondary winding (3sa-c) of the transformers arranged in a second enclosure (6a-c). In other aspects of the invention a method and a computer program for carrying out the method are described.

Abstract: The invention discloses a switching device (3) for disconnecting or connecting an electric machine (10), a converter 10 or a plurality of electrical loads supplied with AC power from a power supply (4) and controlled by a control unit (6). The switching device comprises a current sink (2)and at least one mechanical switch (1) in the switching device (3) are arranged in a circuit. The current sink is arranged, upon receipt of a signal, to close and sink the current, and the at least one mechanical switch (1) is arranged to open and break the current on receipt of a signal to open supplied to the electric machine (10) when the current load is at or close to zero.In other aspects of the invention a method and a computer program for carrying out the method are described.
