摘要： The current transformer includes a primary current conductor (10), wherein there are two current loops (30, 40) connected in parallel and essentially circular in shape and at least one gradiometer (50, 60) shaped essentially as a planar circle. The current loops (30, 40) of the primary current conductor (10) are located co-centrically on top of each other in parallel planes located at a distance from one another. The gradiometer or gradiometers (50, 60) are located in between the current loops (30, 40) in a plane or planes, which are in parallel with the planes of the current loops (30, 40). The primary current flowing in the current loops (30, 40) of the primary current conductor (10) is connected with the aid of a magnetic field to the said gradiometer or gradiometers (50, 60) and in the gradiometer or gradiometers (50, 60) it brings about a voltage proportional to the primary current.

摘要： The invention concerns an apparatus for metering of electric energy, which comprises a box-like case consisting of a bottom part (20) and of a cover part (30). The box contains various metering, control and equivalent modules (M, 50, 70, 80, 90) necessary in a meter. The box of the meter also contains a compartment (50), into which various auxiliary function cards (60) can be installed, such as receivers of network commands, communication means necessary for remote reading, and equivalent. This compartment (50) is opened into an opening (37) that has been formed in the forward edge (30c) of the cover part (30) of the meter box, so that the auxiliary function cards can be installed into the compartment (50) without opening the box of the meter. At the forward edge (20c) of the bottom part (20) of the meter box, a connector block (40) is placed, whose shield cover (100) also extends so that it covers the opening (37) on the cover part (30) of the box and, thus, the auxiliary function cards (60). Thus, the auxiliary function cards (60) are placed under the cover (100) of the connector block (40) and under its seal. Further, if necessary, the auxiliary function cards (60) can be locked in the compartment (50) so that they can be removed exclusively so that the cover (30) of the box is opened and that the calibration seal of the cover (30) is broken.
