Abstract: Antenna having a housing (3), a core (1) and a coil (2), which is wound around the core (1), the core (1) with the coil (2) in a potting compound (5) being mounted in the housing (3), the potting compound (5) being softer than 40 Shore A.

Abstract: A magnetic device, such as a common-mode choke, comprising a base with a hollow stud to skewer and centre the toroidal core; and an insulating anchor with an axial bushing and a plurality of radial hooks, which is used to push the wound torpid against the base, hold the assembled device together, and insulate the windings from each other. Base and anchor are coupled and hold together through a snap-in, interlock mechanism.

Abstract: Motor drive with a T-type filter with at least two three-phase differential mode reactors and three capacitors, wherein at least one of the three-phase differential mode reactor comprises an auxiliary coil (6) wound around three wound core elements (2.1, 2.2, 2.3) such that the common mode current is induced in the auxiliary coil (6).

Abstract: A method for retrofitting a power plant includes the steps of: removing the original active part, removing the original non-active part, providing a new active part that is larger than the original active part, and at least partly extends over a zone that was before occupied by the original active part, and at least partly extends over a zone that was before occupied by the original non-active part, and is housed within the foundation.

Abstract: The static exciter (1) of an electric generator (2) has a main transformer (8) with a high voltage side connected to the grid (5) and a low voltage side connected to a field circuit converter (9) that feeds a generator field circuit (3). The static exciter (1) includes a control unit (11) arranged to detect the status of the grid (5) to cause at least a capacitor bank (13) to supply energy to said generator field circuit (3) in case the voltage of the grid (5) falls below a prefixed voltage value. The capacitor bank (13) is connected between the low voltage side of the main transformer (8) and the AC side of the field circuit converter (9).
