A method for detecting a loss or an undervoltage condition of phase of an electric converter unit (30), characterized in that the method comprises: determining (410) an extremum value, such as a maximum and/or a minimum value, of a phase voltage of the electric converter unit (30) for at least one fundamental period of the phase voltage, and comparing (420) the extremum value to a first threshold value, and if, based on the comparison, a first threshold criterion related to the first threshold value is satisfied, then determining (430) the loss or the undervoltage condition of phase.
