A bilateral comparison between NIST quantum-based power standard and NRC current-comparator-based power standard

The results of a bilateral comparison on active/reactive power meter calibrations between the National Institute of Standards and Technology (NIST) and the National Research Council (NRC) will be 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, 5A, 50 Hz and 60 Hz, at power factors of 1.0, 0.5 lead and lag, and 0.0 lead and lag.
