Abstract

The invention provides methods and systems for protecting electrical transformers or components from overloads when an electrical grid is turned back on following a power outage. It is possible to use power consumption data derived from electrical profiles collected from meters, along with outdoor temperatures associated with each electrical device. A regression analysis may be applied to the power consumption data and to the outdoor temperature data for each of the electrical devices. The regression parameters may be introduced into a trained machine learning model, with additional parameters characterizing the power outages and/or the electrical devices affected by the power outages, in order to predict the load behaviour of the electrical devices after the outage when power has been restored. At-risk electrical devices are able to be protected by postponing turning them back on when the power supply is restored.

Abstract

A process for purifying raw carbon nanotubes to obtain a content in metallic impurities of between 5 ppm and 200 ppm. The process includes an increase in the bulk density of the raw carbon nanotubes via compacting to produce compacted carbon nanotubes. The process further includes sintering the compacted carbon nanotubes by undergoing thermal treatment under gaseous atmosphere in order to remove at least a portion of the metallic impurities contained in the raw carbon nanotubes, and consequently producing purified carbon nanotubes. These purified carbon nanotubes are directly usable as electronic conductors serving as basis additive to an electrode material without requiring any subsequent purification step. The electrode material can then be used to manufacture an electrode destined to a lithium-ion battery.

Abstract

A system and a method for locating a defect between detection points upstream and downstream of an underground portion of an electricity grid are disclosed. Detection units are respectively arranged at the detection points. The units have sensors for picking up a breakdown traveling wave propagated by one or more cables of the underground portion from the defect to each detection point. A logic circuit acquires each picked-up signal and determines a time of arrival of a wavefront of the traveling wave present in each signal in accordance with a GPS-synchronized time signal. A processing unit computes a distance between one of the detection units and the defect on the basis of the times of arrival, a known length of the underground portion between the sensors, and a known propagation speed of the traveling wave in each cable. The distance is displayed on a display.
