Supporting industry through increased access to AC quantum voltage references
Quantum effects play a fundamental role in the redefinition of the SI electrical units, allowing their direct realisation. Currently, most NMIs and some industrial laboratories possess a quantum standard but these needed to be improved and their metrological applications extended to other voltage levels and frequencies,so that their use can also be extended to industrial calibration laboratories and further levels of the traceability chain.
This project tackled that problem by providing European National Metrology Institutes (NMIs) the access to AC quantum voltage standards, therefore contributing to spread the capacity to countries or regions in Europe where access to these facilities was limited. The project also established the basis for the future collaboration between metrology institutes working on AC quantum voltage standards.
