Abstract: A method for monitoring an electrical installation comprises: while the installation is in operation, measuring electrical currents that flow through the installation and temperature values at predefined locations in the installation; using a numerical model acquired beforehand, computing a numerical index representative of thermal properties of the installation, from differences between the measured temperature values and corresponding temperature values estimated by means of said model from the measured current values; and detecting a thermal anomaly when the computed numerical index differs from a reference value.

Abstract: An electrical connector including a conduction portion having two terminals intended to be each connected electrically to a connection terminal of an electrical apparatus, the connector further including a dissipation portion of the same material as the conduction portion and having a cellular structure defining a plurality of cells.

Abstract: The invention relates to a gas deionization device and an arc extinguishing chamber notably for a multipole low voltage circuit breaker with a molded case. A porous shield comprising one or more superposed metallic wire cloths. Each cloth is formed by a criss-crossing of straight wire yarns spaced apart from and parallel to one another with tight joined undulated wire yarns that extend appreciably perpendicular to the straight wire yarns, and pass alternately over and under at least one of the successive straight wire yarns. At least three superposed wire cloths have progressive mesh openings.
