Abstract

Inductance is realized at Spanish Centre of Metrology (CEM) by means of a modified coaxial Maxwell- Wien bridge. A study of the unequalized currents in the whole bridge network was carefully carried out in order to check their effect on the system’s accuracy. Previously, stability and thermal coefficient of different kind of inductors have been evaluated to select those with the lowest temperature coefficient and best short-term stability to be employed in this evaluation.
