Abstract
In the liberalized market context, the measures done on the electric systems assume a crucial role for the invoicing of the energy, and also for the provision quality assessment in electric energy in a given network zone .Among the nuisances, the harmonic distortion has the most considerable weight, because of the non linear loads proliferation, which leads the non sinusoidal currents and voltages.
Among the different problems led by the harmonic distortion but even resolute, there is two important aspects and bound to which intimately one must cope: the measure instrumentation synchronization and the reactive energy numbering with the electronic meters. With regard to the sizes measure defined by the IEEE norm, a virtual tool has been imagined, while using a technique in the domain time for the voltage and current fundamental extraction [6], on the basis of these works we led a survey the reactive energy electronic counters behaviour in harmonic distortion presence.
The first results underline, that in sinusoidal regime the different methods with which are driven the reactive energy measure lead to the same result, while for the diet disrupted the electronic counters bring to a different answer.
