A comparison of the phase of existing shunts for currents between 10 A and 100 A and frequencies from 500 Hz to 100 kHz has been organized. The measurements were performed at INRIM using a first prototype of a new type of phase comparator and a step-up method for the data processing. The results of the relative measurements have shown a good repeatability, but the method for the evaluation of the reference value still needs some improvement.

Three countries in South America are jointly developing a reference system for measuring electric power up to 100 kHz. The objective is the construction of three similar measuring systems, one for each institute. The measuring system, its design requirements, and the current status of its development are described. This project will contribute to provide calibration services in measuring ranges still not covered by the three institutes.

“…Two types of resistive shunts with rated currents of 50 and 100 A are widely used in NMIs. The first type of shunt employs Manuscript cage-like design as a two-terminal pair resistor [3]. The other type of shunt is a coaxial design of resistive alloys in metal foils developed by Bundesamt für Eich-und Vermessungswesen (BEV), Austria [4].…”

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.
