| Zusammenfassung | A novel method for AC current measurements with quantum traceability to the SI is validated. This method is based on the replacement of thermal converters by digitisers characterized by Josephson voltage systems. In contrast to the traditional thermal converter technique, this new method allows reduced measuring times and the analysis of dynamic signals. Validation results show error differences in the order of 2·10-6 for the shunts resistance ratio for both, simple and dynamic signals. Such a performance in the accuracy and the feasibility of dynamic signals makes this new method very suitable for the use in current traceability chains in the near future. |
