Abstract

NIST is now offering broadband, ac-dc difference calibrations of current shunts from 3 A to 100 A, and at frequencies up to 30 kHz, as special tests. We present an overview of this new service including the design and construction of the NIST standard, high-current shunts. We describe the build-up procedure and two-stage current transformers being used to characterize the NIST standards, as well as the uncertainty analysis for these calibrations. Future plans, such as the extension of the frequency range up to 100 kHz, are also discussed.
