Comparison of high frequency AC-DC voltage transfer standards at NRC, VSL, PTB and NIST

The paper summarizes results of two international comparisons relating AC-DC voltage transfer standards of the National Research Council of Canada (NRC) to the standards of VSL, PTB and NIST. The first comparison was part of the CCE 92-05 Intercomparison of AC-DC Voltage Transfer Standards at HF (1-50 MHz), designated as a key comparison, with results published before NRC participation. The second comparison was carried out using a calorimetric thermal voltage converter of NRC design. Results of comparisons conducted so far show very good agreement between NRC and the three other NMIs in the frequency range from 10 Hz to 100 MHz.
