1. A method of automatically detecting electrical installations likely to exhibit an electrical non-conformity (ENC) on an electrical distribution system, the electrical installations being connected to meters, the method comprised of the steps of:
a) retrieving, from a data management system, electrical profiles associated with the electrical installations, the profiles being generated by the meters deployed by electrical utilities for billing purposes from measurements taken by said meters, the profiles being spread over time;
b) recovering, from a database, nominative data characterizing the electrical installations, the nominative data comprising at least one of the following information, for each of the electrical installations: nature of the electrical installation among single-phase or multi-phase, tariff to which the electrical installation is subject, purpose of the building(s) associated with the electrical installation among a residential purpose, a commercial purpose, an institutional purpose or an industrial purpose, and main source of energy used to heat the building(s);
c) selecting at least a portion of ENC indicators to apply to the profiles according to the information included in the nominative data among positioning indicators, state indicators and non-technical loss indicators;
d) applying, with IT tools, algorithmic processing associated with the selected ENC indicators, according to target conditions, on the electrical profiles collected in step a), in order to obtain data indicative of different types of ENC;
e) detecting, by the one or more computing devices, from the data obtained in step d), the electrical installations likely to exhibit an ENC, when the target conditions are met;
f) confirming or denying, by the one or more computing devices, that the electrical installations detected are indeed likely to exhibit an ENC, by cross-referencing said nominative data with the indicators of an ENC having met their target conditions; and
g) generating, by the one or more computing devices, a structure of results including data indicative of the different types of potential ENCs identified for each of the confirmed electrical installation;
the method requiring only electrical profiles generated by the meters, and the one or more computing devices, to identify electrical installations likely to be non-conforming, without the use of any other sub-metering equipment.
