Abstract: A sintered magnet, the sintered magnet including a core portion, a shell portion arranged at an outer part of the sintered magnet, and a diffusion portion arranged at least partially between the core portion and the shell portion. The shell portion has a coercivity, which is at least 30 kA/m larger than the coercivity of the core portion. In the diffusion portion, the coercivity is not less than the coercivity of the core portion and not larger than the coercivity of the shell portion and the value of the coercivity gradually increases from the core portion towards the shell portion. The thickness of the core portion is not less than 1 mm and the total thickness of the shell portion and the diffusion portion is at least 5 mm.

Abstract: A multi-terminal surge arrester which includes an active part extending along a longitudinal direction of the surge arrester, a first electrode resting against a first end of the active part, and a second electrode resting against a second end of the active part, which second end opposes the first end in the longitudinal direction of the surge arrester. The surge arrester further includes an insulating fixing device mechanically connecting and fixing the first electrode and the second electrode, and an insulating housing arranged around the active part. The active part includes at least two metal-oxide based varistor elements and a further electrode arranged between the at least two varistor elements, which further electrode provides an externally accessible electrical connection. Therein, the surge arrester is adapted for being insulated by surrounding air.

Abstract: This application concerns a magnet having a magnet body as well as a method for manufacturing such a magnet. The magnet body has a first region with first magnetic properties and a second region with second magnetic properties that are different to the first properties. Owing to the manufacturing process of the magnet body, the relative location of the first region and the second region within the magnet body is freely predeterminable.

Abstract: A system for transient over voltage protection of a three-phase transformer. Two surge arresters are series connected across each winding of the transformer and the center point connection of the two surge arresters is electrically connected to a middle location of the winding. Three additional surge arresters are electrically connected from each phase to ground in the case of either a delta or Y connected transformer; and/or connected from a neutral point to ground in the case of a Y connected transformer. The system allows for all of the surge arresters to be packaged as an integrated surge arrester system to minimize induced transient over voltages and high stresses on the transformer winding due to internal resonances.

Abstract: A surge arrester (100) and a method for manufacturing the surge arrester (100), the surge arrester (100) comprises a preassembled active part (110) extending in a longitudinal direction (Y), and a separately produced flexible housing (120) defining a bore (121) in the longitudinal direction (Y) and having an opening at an end surface (126) of the flexible housing (120), the flexible housing (120) is arranged surrounding the active part (110) via the bore (121) and in contact with the active part (110), the contact causes a deformation of the flexible housing (120) in a circumferential direction (C), and the deformation generates a pressure applied on the active part (110) along a radial direction (R).
