An electric current transformer including a first coil and a second coil, which are produced with a first printed circuit including a first positioning device, and a second positioning device; and a first magnetic part including a first holding device and a second magnetic part including a second holding device, the positioning device being arranged to join together with the holding device so as to hold reference faces of the magnetic parts a predetermined distance away from the turns of the first and second coils. A current measurement unit includes such a current transformer.

Electric current transformer and current measurement unit

A system for measuring an electrical quantity of a current circulating in an electrical device mounted on a mounting support, including an electrical power supply device, the device for measuring the current circulating in the device, the device for tapping the voltage at the terminals of the device, and the device for measuring this voltage, device for processing the measurement information, and device for communicating the measurement information to a receiver. This system includes a first main module, including the power supply device, the current and voltage measurement device, the processing device and the communication device, and a second auxiliary module, including the voltage tapping device and electrical connection device connecting with the main module, this connection making it possible to supply voltage to the main module and to measure the voltage recorded by the auxiliary module, the second module including electrical coupling device for connecting to the terminals of the device to be measured, these device being adapted to the configuration of these terminals.

Device for measuring at least one electrical quantity of a current flowing through at least one electrical device

The present invention relates to an electric protection apparatus comprising at least one switching module fitted on a mounting support, and a control device with an electromagnetic coil juxtaposed with one of the above-mentioned modules, this device comprising a magnetic shield arranged in a plane substantially perpendicular to the plane of the mounting support, said shield being located between the control device and the switching module situated closer to said device, facing the coil of the control device, and comprising at least one ferromagnetic part shaped in such a way that said shield performs magnetic guiding of the arc as soon as separation of the contacts takes place so as to increase the propulsion component of the Laplacian force acting on the arc as soon as separation of the contacts takes place.

Electric protection apparatus comprising at least one breaking module controlled by a control device with electromagnetic coil

The present invention relates to an electrical switchgear unit designed to be fixed onto a fixing support and comprising at least one electrical switching module and at least one module housing a complementary electrical function, at least one of the complementary modules being situated next to at least one of the above-mentioned switching modules, the or each switching module comprising an arc extinguishing chamber. This unit is characterized in that the arc extinguishing chamber of the module situated facing the complementary module presents a cambered face towards the inside of said arc extinguishing chamber so as to create a space E,F inside said chamber enabling a part of the volume of the complementary module to be housed, and in that the ends of said arc extinguishing chamber encroach on the volume of the complementary module.
