Abstract: Electronic device and a method for operating an electronic device providing an improved initialization of the electronic device. Operational data such as software components or configurational data are stored in a removable storage device during the operation of the device. By removing the removable storage device and inserting the removable storage device into another device, the other device can be automatically initialized and configured similar to the former electronic device.

Abstract: The invention is concerned with a current-transformer arrangement for a static electricity meter, including a primary conductor carrying the alternating current to be measured and a secondary winding consisting of at least two coils connected in series, the output voltage from which is passed to an electronic integrating stage to produce a measuring signal independent of frequency.

Abstract: A device for use in connection with electricity meters incorporating current transformers is disclosed. The device detects saturation incidents of the magnetic cores of the transformers, thereby reducing measurement errors.

Abstract: A transducer for current measurements includes a flat conductor with at least two main current branches for the current to be measured and at least a cross-branch current bridge connecting two locations of differing potential of the two main current branches. A magnetic core is laid around one of the branch current paths. The flat conductor is formed such that it is provided in its cross-direction with a bending edge for redirecting current and each main current branch or part thereof at least approximately coincides with and is of an opposite current direction to a main current branch or part thereof of the other leg.

Abstract: A current transformer equipped with a primary winding (1), a secondary winding (2), as well as a detector winding (3), has a rigid coupling between the secondary winding (2) and the detector winding (3). The coupling factor between these windings (2, 3) and the primary winding (1) is considerably smaller than one, since only one portion of the magnetic flux .phi..sub.1 created in the primary winding (1) by the current I.sub.1 to be measured is detected by the detector winding (3). This partial flux .phi..sub.13 is compensated by the flux which is created in the secondary winding (2) by means of a variable-gain amplifier.

Abstract: The current to be measured (I) within a conductor (1), is branched into two conductors (3, 4) of the same conductor material, which have a resistance differing relatively little from one another and at opposite winding direction form the primary winding of an active current transducer. The secondary current (i) is determined by the resistance ratio of the two individual conductors (3, 4). Through mechanical, and therewith thermal contact between the two individual conductors (3, 4), their resistance-ratio is also maintained at high temperature coefficients and at higher conductor temperatures.

Abstract: A transducer for measurement of a current includes a magnetic core, a single U-shaped flat conductor which has two wings, and a crown joining the wings. Each wing has two openings, and the magnetic core passes through the openings. The two wings constitute two conductive branches in thermal contact with one another, and each branch is adapted to carry a component of the current; the current component carried by one branch differs from the current component carried by the other branch. The current components give rise to opposite respective component fluxes in the magnetic core.
