摘要

patent summary: "electrical energy calculation system, electrical cabin comprising one of these systems, associated transformer substation and calculation process". The present invention relates to a system comprising: a first device comprising an element for measuring voltage of a primary conductor, a means for sampling the measured voltage, a means for transmitting a first message, and a means for determining a set of variable values representing the voltage based on the voltage measured over a given transmission period; at least a second device having a current sensor for determining the intensity in a secondary conductor, connected to the primary conductor, a means for sampling the average intensity; and an element for calculating said energy including a means for receiving the first message and being configured to calculate an energy during the given transmission period based on said data set and intensity samples associated with the energy. transmission period. the determining means is configured to determine said data set, based on a correction coefficient, which depends on a value representative of the voltage only for each voltage period, wherein said value is greater than a threshold .
