Abstract
The disclosed method detects anomalies in an electrical network. An ohmic matrix model of the network is initially generated from consumption measurements produced by meters connected to a same transformer. The model has currents carried by the meters as input, relative voltage drops of the meters referenced to a voltage of a reference node located on the network as output, and resistive quantities initially determined by currents and voltages based on the consumption measurements as matrix terms, the relative voltage being a voltage difference between a voltage determined for a meter and an average of voltages determined for a set of meters of the network. The model is iteratively modified according to detected anomalies, and a diagnosis of the network characterizing the detected anomalies is provided.
