“…Measurements have shown that, if interchanging the shunts in a stepup from position high to low, the measurements differ up to 20 A/A from the previous value. A usual way is to calculate the mean value for the next step [3]. However, this approach may introduce a systematic error that can be derived from: The calculation of this error in a stepup from 20 A to 40 A in equation (1) shows an influence dependent on the possible different interaction of each of the two shunts with the capacitances of the tee.…”

“…Therefore, it is impossible to precisely measure the voltage across the shunt at high submillisecond width pulse current input. Theoretical AC-DC coaxial shunts which are commercially available or developed at NMI [2] are 100 A maximum rating.…”

This paper describes a method to calibrate a commercial coaxial shunt resistor with 0.07 % of standard uncertainty at 1200 A, 0.5 ms pulse width current. In the method, a special current shunt is used as the new working standard in Measurement Standards Center (MSC) of Agilent Technologies International Japan. The shunt was designed for currents up to 1500 A at both pulse and DC, and then characterized at DC using a known DC shunt. The impedance characteristic is evaluated at pulse by comparing the voltage across the shunt with the commercial coaxial shunt resistor at the pulse current.

“…The NRC shunts have been previously described in detail in our publications, [1][2][3]. The highaccuracy calibration of ac/dc shunts is not trivial [4], and a significant improvement in its range and significant reduction in uncertainty was achieved thanks to a joint effort of the metrological community.…”

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.
