    Abstract: A method is disclosed for monitoring at least one subsea electric machine supplied by a system for electric power transmission. The system has a power supply, a controller and an AC power line connecting the at least one machine with the power supply. The method comprises the steps of: receiving at the controller, high speed data from at least one subsea sensor arranged between the subsea side of the AC power line and the at least one subsea electric machine, wherein the high speed data includes measurements of an electrical parameter for the at least one machine; and comparing the one or more measurements to a predetermined value. Asystem for electric power transmission arranged for operating at least one subsea load or electric machine is also described.

    Abstract: The invention concerns a system for operating an electric machine and a method for protecting an operation control unit in such a system. The system comprises an operation control unit (20), an alternating current cable (16) connecting the machine (30) with the operation control unit and an electric short-circuiting arrangement (26). This arrangement is connected to terminals of the operation control unit facing the cable and short circuits these terminals based on a detected overvoltage.

    Abstract: The invention comprises a drive controller arranged to provide electrical power from a power supply (10) to a machine (8) or load, over a long AC power cable of the order of kilometers. The drive controller (4) is arranged with circuits and/or control processes to provide AC current at a constant ratio of voltage and frequency to said machine (8) or load. The drive controller maintains voltage and frequency at the machine terminals despite fluctuations in voltage and/or frequency that would ordinarily be caused by the load. This is done by estimating the voltage and current at the machine terminals and adapting the drive controller output accordingly to actively vary the converter output dependent on the load of the machine or other load. In other aspects of the invention a method and a computer program for carrying out the method are described.
