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: Data processing method for analysis of the energy consumption of a site on the basis of measurements including: selection of data time series, segmentation of the time series into segments, projection of the segments, display of the projections of the data segments, e) selection of at least one first group of data segments, establishment of a digital model of classification characterising the first group of data segments, selected on the basis of calendar metadata establishment of a digital model of classification characterising the first group of data segments, selected on the basis of the segments' profiles (FIG. 5B).

Abstract: A method is provided for determining the structure of an electricity transmission grid, including a power supply station including one or more feeders for supplying electrical power to a plurality of electricity consumers, the method including acquiring first data relating to the electrical power consumed by each consumer during various time intervals; acquiring second data relating to the electrical power delivered by each feeder during the various time intervals; generating a plurality of different classes of data; calculating a first selection criteria for each class of data; selecting a first set of classes of data from the classes generated; and determining connection parameters.

Abstract: A casing applicable to a portable electronic device includes a supporter and a casing body having a back surface and side surfaces connecting to the back surface. The back surface has a camera opening for exposing a camera shutter of the portable electronic device and a supporter opening having a bevel side not parallel to the side surfaces. The supporter connected to the bevel side includes first and second sides which define a vertex angle. The supporter is adapted to rotate between a covering position and a supporting position. When at the covering position, the supporter covers the supporter opening, and the vertex angle and the camera opening are arranged diagonally. When the supporter is at the supporting position, the casing is supported by the vertex angle and one of the side surfaces away from the camera opening for the portable electronic device to perform landscape or portrait display.
