| Popis: | This paper describes mathematical modeling of cage-type ac current shunts. A calculable model was developed using lumped circuit elements. The transimpedance, ac–dc difference, and the phase angle error of a shunt can be derived from the model. An uncertainty analysis of the model was done by means of Monte Carlo methods. Comparison of the calculated and measured values shows an agreement better than 6 $\mu\Omega/\Omega$ in the ac–dc difference and 110 $\mu{\rm rad}$ in the phase angle error at frequencies up to 100 kHz. |
