Abstract :
The simultaneous synchronous generation and sampling technique allows alternating current (AC) quantities (root mean square (RMS) values of voltage, voltage ratios, and power) to be determined with uncertainties of the order of a few parts in 10^6. Mathematical models for estimating measurement uncertainties and experimental comparisons of such a system against existing primary standards at the PTB were carried out.
