Current-transformer arrangement for an electrostatic meter

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.

Electricity meter with arrangement for monitoring core saturation

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.

Active current sensor with primary reducing winding

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.
