Abstract: A transformer arrangement and transformer for mitigating transient voltage oscillations. The transformer included a transformer core enclosing at least one core leg. A winding is wound around one of the at least one core leg. The winding extends from a first winding terminal to a second winding terminal and includes a first winding section along a first conductor extending from the first winding terminal to a first intermediate end point, and a second winding section along a second conductor extending from a second intermediate end point to the second winding terminal. The transformer arrangement further includes an external passive electric component connected between the first intermediate end point and either the second intermediate end point or the second winding terminal arranged to decrease an effective difference between capacitive and inductive voltage distributions between the intermediate end points such that transient voltage oscillations in the winding are mitigated.

Abstract: A converter valve unit including a plurality of parallel connected controllable semiconducting elements. A free-wheeling diode is connected in anti-parallel with each semiconducting element. A control unit is configured to control each semiconducting element. A current sensor is connected to each of the parallel connected semiconducting elements. The current sensor is configured to sense a current of each semiconducting element by measuring a voltage over the current sensor.

Abstract: A component feeder including a lift for elevating a selection of components from a bulk storage, and a pick surface adjacent to the lift for receiving the selection of components. A spreader gives the selection of components a push for spreading the selection of components from the lift on the pick surface. The combination of a vertical lift and a separate pick surface adjacent to the lift enables the bulk storage being positioned right below the pick surface. The area of the pick surface is large in relation to the total footprint of the component feeder.

Abstract: A network manager device in an industrial wireless network sends a network investigating message to other network nodes for processing and forwarding through the network, the message including a message weight. A wireless communication device providing a node in the network receives the message from another network node, determines a communication weight based on the quality of communication, adds the communication weight to the message weight and compares the sum with the node weight. If the sum is lower than the node weight, it is set as new node weight and as new message weight, whereupon the changed message is sent to other nodes in the network. The network manager device maps the topology of the network based on updated node weights, sets a communication scheduling scheme based on the mapped topology and informs the network nodes of the scheme.

Abstract: A voltage sensor includes an insulator with mutually insulated electrodes embedded therein. The electrodes are coaxial and cylindrical and overlap axially along part of their lengths. They are mutually staggered and control the surfaces of electric equipotential such that there is a substantially homogeneous electric field outside the insulator and a substantially homogeneous but higher field within a sensing cavity within the insulator. A field sensor is arranged within the sensing cavity to locally measure the field. This design allows for the production of compact voltage sensors for high voltage applications.
