  • Patent number: 8552701
    Abstract: The present invention refers to a system for regulating a load voltage (C) in power distribution circuits comprising at least: a regulation transformer (2) the secondary winding of the regulatory transformer (2) being operatively arranged in series between a power source (F) and the load (C), the power source (F) being capable of providing a supply voltage (VAL) to the load (C); a measuring device (5) operatively associated to the load (C), the measuring device (5) being capable of measuring at least one value of an electric signal of the load (SCA); a control device (4) operatively associated to the measuring device (5), the control device (4) being capable of comparing the value of the electric signal of the load (SCA) with a pre-established reference value and providing a correcting electric signal (SCO); and an actuation device (3) operatively associated to the control device (4), wherein the actuation device (3) is capable of providing an adjustment voltage (VAJ) proportional to the correcting electric s

  • Patent number: 8212645
    Abstract: A method for producing a transformer core with layers of core laminations includes forming at least one core lamination of at least two segmental laminations. An end region of a first segmental lamination has a straight crosscut edge. The straight crosscut edge of the first segmental lamination together with a corresponding straight crosscut edge of an end region of a second segmental lamination forms a form-locking straight abutting edge. The straight abutting edge is at an angle relative to the longitudinal direction of the end region of one of the segmental laminations of the first core lamination. Using core laminations having different angular orientations of the abutting edges, avoids magnetic losses such as those occurring when using conventional layering techniques. Simultaneously, an intermediate space created by conventional layering techniques between individual core lamination packs can be minimized, and thereby susceptibility to corrosion can likewise be reduced or completely avoided.
