An arrangement for compensating disturbance voltages induced in a transformer is disclosed. In an embodiment an arrangement includes a transformer component comprising a transformer winding and an ancillary apparatus, wherein the ancillary apparatus comprises an auxiliary winding, wherein the auxiliary winding is connected in series with the transformer winding, and wherein the ancillary apparatus is arranged and designed such that an interference voltage induced in the transformer component is reduced by a counter-voltage induced in the ancillary apparatus.

Arrangement for compensating disturbance voltages induced in a transformer

An inductive component having a coil with a winding of a wire and a molded body adhering to the coil. The molded body has a surface for the arrangement of a heat sink. A method for producing such a component is also specified, in which, to produce the molded body, a mold is filled with a potting material and the mold is subsequently removed.

Inductive component

An inductive component and a method for producing an inductive component are disclosed. In an embodiment the inductive component includes a mounting device, a magnetic core, at least one winding of a wire wound around the magnetic core and a latching device, wherein the core is secured to the mounting device by the latching device.

Inductive component and method for producing an inductive component

An arrangement for measuring a current flowing in an electrical conductor includes a magnetic circuit, for coupling to the electrical conductor, the magnetic circuit has an air gap. A magnetic field-sensitive component that serves for measuring the magnetic field generated by the electrical conductor is situated between the arms of the magnetic circuit. Two control cores are arranged in the air gap of the magnetic circuit. The control cores each include a control winding for magnetically saturating the respective control core and are arranged on both sides of the electrical conductor.

Arrangement and method for measuring a current flowing in an electrical conductor

An arrangement and a method are used for measuring current flowing in an electrical conductor with a magnetic circuit that has an air gap for coupling to the electrical conductor. The air gap of the magnetic circuit contains a magnetic-field-sensitive component that is used to measure the magnetic field generated by the electrical conductor, wherein, the air gap of the magnetic circuit contains a control core, wherein the control core has a control winding for the magnetic saturation of the control core. In the vicinity of the magnetic-field-sensitive component there are several additional elements that are suitable for conducting interfering magnetic fields in the surroundings of the magnetic-field-sensitive component independent of the control cores.
