A method for sampling the electrical signals of a multiphase electrical installation enables the samples on a predetermined phase to be corrected from the samples on the correct phases, with a fixed sampling period, comprising: (a) supply of samples successively on each of the phases, (b) superposition of a part of the samples of each of the correct phases over the same fundamental period, (c) determination of a limit for each of the correct phases, (d) selection of a series of consecutive samples on each of the correct phases, the first sample of the series having a sampling index equal to the limit, and (e) correction of a series of the first consecutive samples of the predetermined phase from the values of the samples of the selected series. A device for sampling the electrical signals comprising means for supplying samples and processing means enabling implementation of the method described above.
