| Zusammenfassung | The long established sampling system for measuring active, reactive and apparent power at power frequencies at the Physikalisch-Technische Bundesanstalt (PTB) is currently being combined with an ac waveform generator based on programmable arrays of Josephson junctions. This combination will allow linking measurements of electrical magnitudes (120 V, 5 A) at power frequencies with a quantum based standard beyond previous efforts. Moreover, it will enable achieving uncertainties below 1 μW/VA (k=1) for active, reactive and apparent power at the 600 VA apparent power level. |
