Zusammenfassung
This paper presents a step-up method for calibrating a set of error compensated current comparators of PTBs instrument transformer laboratory for the use as current transformer reference standards. The method is based on some assumptions and previous knowledge about the error characteristics of first CC of the set. Extensive measurements between the CCs confirm the assumptions made and show for first CC, that its ratio and phase errors are in the 10-7 range, while its uncertainties are in the same order.
