Abstract: An electrical power system for stationary or movable subsea loads (7) provides one common feeder for multiple electric motors which can be individually controlled. Operational flexibility and operational safety for operation in varying water depths is provided by encapsulating electrical functional element (6) of a subsea power system with a subsea electrical distribution system (5) individually or in-groups. Electrical functional element (6) and their semi-conductor elements are arranged within at least one fluidized internal pressure casing (13). An external pressure casing (12) is provided for the subsea electrical distribution system (5) and/or other components of the subsea system. A high frequency power transmission to the subsea pressurized distribution system (5) with pressurized semi-conductor components reduces weight and size of subsea transformers (4b) and cables (9) employed in subsea systems (10).
