“…Their laboratory has a lot of experiences in foil design high current shunts development (at foil design instead of resistors mounted in cylindrical cage resistive foil is used). Their design has very small phase displacement and small ac/dc current transfer difference but it doesn't have stable dc resistance [2]. Because of that it is not useful for direct ac current measurement.…”

The dependence of cage-type AC shunt resistance and phase angle on frequency and input current is examined in this paper, for shunts with different current ratings. The AC resistance of shunts remains constant for up to 1 kHz, but the phase angle changes proportionally to the frequency. The results of current dependencies on AC resistance are consistent with each other within measurement uncertainties between 1 A and 10 A. The phase angle does not depend on the current, for values up to 10 A. The effects of current heating of shunts are also evaluated. The thermal time constant of shunts is found to be approximately 200 s and does not depend on the shunts and the input current frequency.

This paper describes a new method for determining phase angle errors of shunts with rated currents at 50 and 100 A at frequencies from 25 to 100 kHz. The method is based on the use of a three-branch binary inductive current divider to measure the phase angle errors of high current shunts against a phase angle reference standard with only one step. An inductive high current shunt has been designed using a 100:1 current transformer connected in parallel with a 1-Ω shunt. The phase angle errors of resistive high current shunts and the inductive high current shunt have been measured. The level dependence in phase angle errors of three different types of high current shunts has been evaluated at currents from 1 to 100 A. The measurement results and standard uncertainties of the phase angle errors of high current shunts are reported.Index Terms-Binary inductive current divider (BICD), current transformer (CT), inductive high current shunt, inductive voltage divider (IVD), level dependence, phase angle errors.
