Abstract

A number of international comparisons of power meter calibrations at power frequencies were conducted in the past, all of them being done at 120 V and 5 A. This comparison of power meter calibrations between the National Research Council of Canada and the National Institute of Standards and Technology, USA, was done to include voltage ranges up to 600 V, current ranges up to 100 A, and at power factors of 1.0, 0.5 lead and lag, and 0.0 lead and lag. The comparison was implemented by a transfer standard consisting of a modified commercial time-division multiplier type wattmeter. The results indicate that there are no significant differences in the overall accuracy of AC power measurements in each laboratory up to 600 V, 100 A, at all power factors
