A comparison between the NIST PJVS-based power standard and the NRC current: comparator-based power standard

This paper presents the results of a comparison of active/reactive power meter calibrations between the National Institute of Standards and Technology and National Research Council. The comparison was implemented using a transfer standard consisting of a highly stable commercial sampling-type power/energy meter. Active and reactive power measurements were made at 120 V, 5 A, 50 Hz, and 60 Hz. For active power, the measurements were made at applied current phase angles of 0\ub0, +60\ub0, and -60\ub0. For reactive power, the measurements were made at applied current phase angles of +60\ub0, +90\ub0, -60\ub0, and -90\ub0 . The results of the comparison indicate agreement to within the stated uncertainties of the participants.Peer reviewed: YesNRC publication: Ye
