Abstract:
Wideband current transducers with a voltage output are often used to measure AC currents at frequencies up to 1 MHz. The ratio of output voltage to primary current as a function of frequency is the calibration result of these transducers. A traceable method to measure 1 A alternating current at frequencies of 100 kHz and 1 MHz is reported in this paper. The ratio of the wideband current transducer is obtained with expanded uncertainties of 1.3 % for 1 A, 100 kHz and of 2.0 % for 1 A, 1 MHz.
