Abstract
Some embodiments are directed to a method for detecting harmonic pollution in an electrical distribution network carrying a three-phase current, including a step of measuring the voltages and strengths of the current, for each of said phases, at a counting point of the network; a step of calculating a first quaternion impedance corresponding to the fundamental frequency of the current; a step of calculating at least one second quaternion impedance corresponding to a harmonic frequency of the current, these impedances being calculated by converting the voltages and strengths in a two-dimensional frame of reference defined according to an angle that is dependent on said frequency in order to provide a system of two vectors of three quantities, ud, uq, uo and id, iq, io, respectively.
