Validation Of The New Automatic System For AC Voltage Comparisons

摘要

A system for the automatic comparisons of ac voltage, ac current and ac-dc transfer has been built, which simplifies the management of the whole traceability chain from national standards to the instruments under test. The validation process for ac-voltage and ac-dc transfer has shown the functionality of the system, a high repeatability and self-consistency of the results and a full compatibility with measurements made manually and by the previous automatic system.
