“…Accordingly, signa ation is achieved with a function generator DG4062, which provides the volta signal necessary for the amplifier's input (CTRL IN-12 V max). In the next step, plified signal is forwarded from the amplifier's output (OUT) to two current shun test connected in series with a Tee connector [22], as depicted on Figure 3. Output from the current shunts are forwarded to the analog input channels AI 1 and AI NI 4461 PXI module for sampling.…”

AC current shunts are used for precise current measurements. The application of AC current shunts requires that their amplitude phase characteristics are known. A group of three geometrically identical current shunts and a reference shunt are observed in this paper. The phase characteristics of the reference shunt have been previously obtained. A relative phase comparison has been made between the three geometrically identical shunts, and phase displacement values for each have been obtained. After this, the results are verified with the reference shunt. The relative method is most suitable for shunts, where their respective RC and L/R values are small (compared with 1/ω) and of the same order. The ratios of the nominal resistance values of the shunts used in this paper are at the limit of the given statement. The conclusion is that the method applied at the mentioned limits, in terms of the metrology-grade phase angle determination of current shunts, is not to be considered reliable at frequencies higher than 1 kHz.

NRC offers calibration of ac shunts from milliamperes up to 100 A, in the 10 Hz to 100 kHz frequency band with expanded uncertainties between 10 µA/A for currents in the milliampere range to 50 µA/A at 100 A and 100 kHz. The paper describes the design of NRC ac standard shunts, as well as NRC experience in calibrations of commercial shunts. The ac-dc difference of some commercial low current shunts is load sensitive at higher frequency ranges. The paper discusses reasons for this sensitivity and suggests mitigating solutions.
