Abstract: Telecontrol equipment for an MV/LV substation between a medium-voltage network and a low-voltage network. The telecontrol equipment including a first device configured to power the equipment from the low-voltage network and from an auxiliary source, a second device configured to communicate information gathered by the equipment to outside, a third device configured to monitor the medium-voltage network at the substation level, and a fourth device configured to monitor the low-voltage network at the substation level.

Abstract: A method of configuration by a server module of several client modules connected together via an Ethernet communication network of daisy-chain type is provided. Each client module includes an Ethernet switch fitted with a first communication port and with a second communication port, in such a way that the first port of a first client module is connected to a communication port of the server module and that the first port of another client module is connected to the second port of an adjacent client module. The method includes for each client module an initialization step in which the client module activates its first port and deactivates its second port, an identification step in which the client module communicates with the server module via its first port for receiving an identifier, and an end-of-configuration step in which, once its identifier has been received, the client module activates its second port.

Abstract: A power supply module for intelligent electronic apparatuses and capable of transforming the energy of the LV network and of a battery into energy that can be used by said apparatuses is produced to serve as support for said apparatuses. In particular, for a use in a telecontrol equipment item, the casing of the power supply module is flat, can be installed on wall-mounted DIN rails, and includes, on its front face, a DIN rail for fixing the apparatuses that it powers, that is to say other functional modules of the equipment. The casing also includes an apron for the connections. Preferably, the power supply is produced by series connection, and the power supply module includes a port dedicated to external communication via a module of the equipment.

Abstract: A telecontrol equipment item (10) is adapted to monitor the MV network (3) at the level of a transformer substation and possibly control elements (5) thereof in the case of a fault. According to the invention, the equipment item (10) comprises means (400) for also monitoring the LV network (4). Preferably, the equipment item (10) comprises an LV monitoring module (400), a power supply module (100), a communication module (200) and an MV monitoring module (300i) for each line to be monitored. The different components of the modules are optimized to be adapted to the networks (3, 4) on which the equipment item (100) is installed, and to allow for updates.
