Abstract
The disclosed method corrects consumption measurements provided by meters presumed to be connected to a same network. The measurements taken by the meters at time intervals are collected in a form of samples used to determine electrical quantities in relation with currents and voltages relating to the meters. A selection of a group of retained samples among the samples considered to be valid, corresponding to a load range or a range of load variation ratio carried by the network based on the electrical quantities is performed. Correction functions of the consumption measurements are defined from the group of retained samples, and the consumption measurements are adapted according to the correction functions. An anomaly corresponding to an electrical non-compliance of a meter can be detected by the method.
