摘要： A subsea electrical unit is provided. The subsea electrical unit has a first electric power connection for receiving electric power for operating the subsea electrical unit and a second electric power connection towards a further subsea electrical unit. A line insulation monitor is coupled to the second electric power connection. A control unit is adapted to determine whether electric power is present on the second electric power connection, and is further adapted to disconnect the line insulation monitor form the second electric power connection if it determines that power is present on the second electric power connection.

摘要： An electrical subsea node for communicating data between at least one sensor at a sea bottom and a topside unit above the sea surface may include: a water tight container; a first electronic module extending in a first area of a first area size in a plane of a maximal spatial extent of the first electronic module; and at least one second electronic module extending in a second area of a second area size in a plane of a maximal spatial extent of the second electronic module, wherein the first and second electronic modules are coupled for data communication and arranged inside the container to form a module arrangement extending in an arrangement area of an arrangement area size in a plane of a maximal spatial extent of the module arrangement, wherein the arrangement area size is smaller than a sum of the first and second area sizes.
