METHOD AND DEVICE FOR ANALYSING THE QUALITY OF THE ELECTRICAL ENERGY IN A THREE PHASE ELECTRIC NETWORK

摘要

The invention relates to a method for analysing the quality of the electrical energy in a three phase electric network characterised in that it comprises the steps of: Measuring (El) a set of magnitudes comprising one electrical magnitude per phase Forming (E2) a space vector from an instantaneous three dimensional transformation of the set of measured electrical magnitudes Determining (E3) a set comprising at least one parameter representative of the quality of the electrical energy in the three phase electric network depending on the space vector.
