20150012141 | METHOD AND SYSTEM TO SUPPORT TECHNICAL TASKS IN DISTRIBUTED CONTROL SYSTEMS - A method and computer system are disclosed to support technical tasks in distributed control systems. The system can store a workflow-aware object of a plurality of workflow-aware objects, wherein the workflow-aware object represents at least one component of an automation system. A computation component can be associated with the workflow-aware object, and have an interface to receive specific data of the automation system. The computation component can compute a workflow item based on a workflow item profile with user related information, and based on the specific data of the automation system, wherein the workflow item profile specifies an object reference to the at least one component of the automation system, and wherein the user related information is configured for retrieval of a user identifier associated with the automation system engineer. A workflow item collector can identify the workflow item based on predefined identification rules for communication to the automation system engineer. | 01-08-2015 |
20100025071 | AN ELECTRIC POWER CABLE, AN OFF-SHORE INSTALLATION PROVIDED THEREWITH, AND USE THEREOF - An electric power cable including at least one electric conductor. An electric insulation surround the conductor and includes a polymer. A tubular protective sheath surrounds the electric insulation and acts as a water barrier that prevents water intrusion into the electric insulation. The protective sheath includes a metal as a main constituent. The cable includes at least one density-raising element of a material of higher density than the material of the protective sheath, in order to increase the density of the cable such that too large motions thereof are prevented when the latter is installed in open sea. | 02-04-2010 |
20090314745 | Switch Disconnector - A switch disconnector is disclosed. The switch disconnector has a main contact point and an arc interruption contact point, of which the main contact point opens before the arc interruption contact point during a disconnection operation and is closed after the arc interruption contact point during connection, with a stationary and a moving contact-piece arrangement, with the stationary contact-piece arrangement having a pot contact piece with contact fingers and with the moving main contact point having a contact cylinder which is connected to a contact mount, and with the arc interruption point having a contact pin as the stationary contact piece and an annular contact piece as the moving contact piece. The contact pin has a section composed of interruption-resistant material, whose external diameter is greater than the external diameter of the rest of the pin area. The contact pin has at least one slot which runs in the longitudinal direction and splits the pin into at least two pin fingers. | 12-24-2009 |
20090303761 | CONVERTER STATION AND A METHOD FOR CONTROL THEREOF - A converter station an element adapted to determine a value of an actual temperature of any critical component of the station and an element adapted to determine a value of an actual temperature of any media used to cool the critical component. An arrangement is adapted to utilize these temperature values and information about actual cooling capacity of any cooling equipment present to cool the critical component and information about the thermal behavior of the critical component and the possible cooling media upon a possible change of the power actually transmitted through the station in a mathematical model for calculating the present overload capabilities of the converter station for use in the control of converters of the station upon a possible request of utilizing an overload capability of the station. | 12-10-2009 |
