On the calibration of direct-current current transformers
Luca Callegaro, Cristina Cassiago, Enrico Gasparotto
Modern commercial direct-current current transformers (DCCT) can measure currents up to the kA range with accuracies better than 1E-5. We discuss here a DCCT calibration method and…
A three-arm current comparator bridge, for impedance comparisons over the complex plane
Luca Callegaro, Vincenzo D'Elia, Massimo Ortolano +1
We present here the concept of three-arm current comparator impedance bridge, which allows comparisons among three unlike impedances. Its purpose is the calibration of impedances h…
Experiences with a two terminal-pair digital impedance bridge
Luca Callegaro, Vincenzo D'Elia, Marian Kampik +3
This paper describes the realization of a two terminal-pair digital impedance bridge and the test measurements performed with it. The bridge, with a very simple architecture, is ba…
