1. A method for processing data pertaining to an activity of partial electrical discharges taking place in a three-phase electric machine (1) powered with square wave voltage, said data comprising a plurality of discharge signals associated with said partial electrical discharges and a plurality of sets of three values (eU, eV, eW) of power supply voltage of the machine (1), each set measured in concurrence with a corresponding discharge signal,characterised in that it comprises the following steps:

  • transforming each set (eU, eV, eW) of three voltage values measured into a corresponding pair (ed, eq) of voltage values;

    deriving a phase value from each of said pairs (ed, eq) of voltage values;

    attributing to each discharge signal associated with a corresponding partial electrical discharge the corresponding phase value, to assess the measured discharge signals as a function of corresponding phase values.
