The invention relates to a device for measuring an electrical quantity of one phase of an AC electric current in an overhead electrical network, comprising: a sensor designed to be attached to an electric line of the network, the sensor including: an electrically conductive plate; an electrical conductor, designed to electrically connect the plate to the line, in order to circulate a first current from the line through the conductor; a processing unit, designed to determine the electrical quantity from value values of the first electric current and a value of a capacitance between the plate and ground. The device also comprises a generator, electrically connected to the conductor and designed to inject a second current through the conductor, the second current having a frequency other than the frequency of the first current, the processing unit also being designed to calculate the capacitance between the plate and ground as a function of the second current.

Device for measuring an electrical quantity of one phase of an AC electric current of an overhead electrical network

In this installation management method for managing an electrical installation, the electrical installation comprises a plurality of electrical elements and each element comprises a first memory storage means for storing a unique identifier associated with said element. This method includes a step of acquisition, via an identification means, of the first identifier of each element belonging to the installation. Each first memory storage means is also capable of saving and storing geometrical data of the corresponding element, the said data being acquired during the data acquisition step, via the identification means, and associated with the corresponding first identifier. The method further includes a step of computation, via a computing unit, of a modelling of the electrical installation based on the geometrical data acquired.

Management method of an electric installation and management system of one such installation

A detector for detecting at least one electric quantity in an electric conductor, and an overhead network for distributing electricity. The detector includes a frame on which a mechanism is fixed, the mechanism including a magnetic toroid, divided into two branches rotatable around an axis defined by the frame, between a separated position and a position closed around the electric conductor, a current sensor, divided into two branches rotatable around an axis defined by the frame, between a separated position and a position closed around the electric conductor, the current sensor performing an AC current measurement, a force transmitting element transmitting a rotational force to the magnetic toroid and the current sensor, the element being provided with at least one portion to receive the conductor by bearing, and a first clamp including two clamp arms, and a second clamp including two clamp arms.

Detector for overhead network and overhead network comprising such a detector

A current sensor including a measurement torus, arranged in a casing positioned around an electric conductor able to transmit an electric current, and a device for detecting a voltage in the electric conductor. The detection device is configured for surrounding the electric conductor when the current sensor is installed.

Current sensor and electric network comprising such a current sensor

An electrical panel having an unpluggable drawer unit that forms a housing for positioning an electrical device, and an Ethernet-type high-frequency communication device that forms a daisy-chain communication subsystem, the one drawer unit including an unpluggable connector to connect or disconnect it to a communication subsystem, and the drawer unit can occupy a first, plugged-in position connected to the communication subsystem, and it comprises a switch that controls a bypass switch of a bypass on the communication subsystem when the drawer unit occupies a second, unplugged position.
