1. A method for classifying at least one partial discharge emitted in an insulator of an electrical conductor of a medium voltage or high voltage electrical device, the method allowing the at least one partial discharge to be classified from between at least a first class and a second class distinct from the first class,
the method comprising:
obtaining, by an electronic control unit, a set of samples, each sample of the set of samples corresponding to a respective at least one partial discharge emitted in the insulator of the electrical conductor, wherein each sample of the set of samples is measured with at least one sensor,
determining, by the electronic control unit, a duration separating two consecutive samples of the set of samples,
determining, by the electronic control unit, a classification model by automatic learning based on at least one statistical quantity of the samples of the set of samples, wherein the at least one statistical quantity of the samples of the set of samples comprises the duration separating the two consecutive samples of the set of samples,
acquiring, by the electronic control unit, a new sample corresponding to at least one new partial discharge, and
determining, by the electronic control unit, a class of the at least one new partial discharge based on the classification model.
