A comparison between the NIST PVJS\uadBased Power Standard and the NRC Current-Comparator-Based Power Standard

摘要

The results of a comparison of active/reactive power meter calibrations between the National Institute of Standards and Technology (NIST) and the National Research Council (NRC) are presented. The comparison was implemented using a transfer standard consisting of a highly stable commercial sampling-type power/energy meter. The measurements were made at 120 V, 5 A, 50 Hz and 60 Hz, at power factors of 1.0, 0.5 lead and lag, and 0.0 lead and lag. The results of the comparison indicate agreement to within the stated uncertainties of the participants.
