| Zusammenfassung | This paper reports the incorporation of a Josephson waveform synthesizer (JWS) into the primary standard for ac electrical power at the Physikalisch-Technische Bundesanstalt (PTB). The increase to 10 V of the amplitude delivered by the JWS has allowed matching of the levels of the signals measured to determine the active, reactive, and apparent power at the 120-V and 5-A level, which is also measured by the device under test. The inherent noise- and drift-free voltages delivered by the JWS allow calibration of the core sampling voltmeter of the PTB primary power standard with an uncertainty of 0.4 μV/V (k = 1) in 100 signal periods and as part of the measuring sequence. |
