Abstract :
Summary form only given. A number of international comparisons of current transformer calibrations at power frequencies were conducted in the past. However, all of them were done with a secondary current output of 5 A. This intercomparison of current transformer calibration systems between the National Research Council of Canada and the National Institute of Standards and Technology, USA, is done with a primary current range of 100 A and a secondary output signal of voltage range of 10 V. The comparison is implemented with a transfer standard consisting of a modified commercial current-comparator-based transimpedance with the output voltage adjustable in magnitude and phase within a range of /spl plusmn/1 percent.
