[54] ELECTRICAL QUANTITY MEASURING APPARATUS AND ELECTRICAL QUANTITY MEASURING METHOD
[57] Abstract: Electrical quantity measuring apparatus (2), comprising: a synchronization module (7) structured to generate a synchronization signal (S1) and a first measurement apparatus (8) connectable to an electrical (1) and structured to receive the synchronization signal and provide: first Fourier transform coefficients representing a first electrical quantity (I(t)) associated with said 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 (S1) at the first measurement apparatus (8). Moreover, the quantity measuring apparatus comprises a processing module (10) 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.
