Abstract
An electrical quantity measuring system includes an electrical circuit of an electrical distribution network and an electrical quantity measuring apparatus. The apparatus includes a synchronization module structured to generate a synchronization signal; and a first measurement apparatus connectable to an electrical circuit and structured to receive the synchronization signal and provide a first Fourier transform coefficients representing a first electrical quantity associated with the electrical circuit and a first delay value depending on a time offset between a measurement instant associated with the measure of the first electrical quantity and a reception instant of the synchronization signal at the first measurement apparatus. The measuring apparatus also comprises a processing module structured to process the first Fourier transform coefficients and the first delay value and provide first time-shifted Fourier transform coefficients representing a first synchronized measured electrical quantity.
