Abstract: The present invention is concerned with the cooling of electrical heat sources, in particular for improving the cooling of a transformer.
A power unit (200) with a heat producing unit (203) comprising at least one heat source (202) and with a cooling unit comprising at least one heat exchanger device (100) and at least a portion of a secondary chamber (209) is provided. The at least one heat source (202) is thermally connected to the at least one heat exchanger device (100). The heat producing unit (203) and the cooling unit (201) are attached to one another such that a substantially closed primary chamber (211) with at least one heat source (202) is formed. The primary chamber (211) is structurally separated from the secondary chamber (209), and the primary chamber (211) and the secondary chamber (209) are thermally connected to one another by the at least one heat exchanger device (100) in an operating state of the power unit (200).

Abstract: There is presented a transformer arrangement for mitigating transient voltage oscillations. The transformer arrangement comprises a transformer. The transformer comprises a transformer core comprising 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 comprises 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 comprises 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: For controlling power flow in meshed power network (30), at least one variable resistance module (11) is inserted into a transmission line (3) of the power network (30). In an external driver (13) an external control effort (14) is produced and applied to the variable resistance module (11) for causing a change of its resistance. For example, a High Temperature Superconductor module or a Liquid Metal Current Limiter module is used as the variable resistance module (11). Accordingly, a heater or a magnetic field inductor is used as a driver (13) for causing a change of resistance of the variable resistance module (11). Using a variable resistance module (11) makes it possible to control power flow in a power network (30) with less wear of components than in conventional electro-mechanical switching compensation and with lower costs than with flexible AC transmission systems devices.
