摘要

Patent of Invention: "DEVICE FOR MEASURING AN ELECTRICAL CURRENT FLOW IN AN ELECTRICAL EQUIPMENT UNIT, THE DEVICE ALLOWS TO MAKE A POWER MEASUREMENT, AND UNDERSTANDING ELECTRICAL EQUIPMENT UNIT". The present invention relates to a device D for measuring at least an amount of electricity comprising a flow of electric current in a unit of electrical equipment, said device being housed in a box designed to be mounted on a stand. This device is characterized by the fact that it comprises a certain number of through holes that form the terminals (2), delineated by a piece made of an insulating subway, this number corresponding to the number of phases of the equipment unit, said holes forming the terminals being designed so that each of them is traversed by a conductor, said conductors being designed so as to be electrically connected, through one of their respective ends to the terminal strips of the equipment unit, called the first one. and across its opposite end to the electrical contact strips of an appliance or at the line side of said first equipment unit and, for at least one of the terminals (2) of the device, a magnetic core (8) that at least partially surrounds the terminal (2) and at least comprises an air gap around which at least one measuring coil, called a secondary coil, is wound between the two end portions of the magnetic core (8) which delineates said air gap, said coil (s). (s) (13) emitting a signal representative of the current flow in the apparatus.
