Abstract

A high-precision multi-range unbalanced transformer bridge designed for inductance standard calibration is described. Basic theory of the bridge is discussed which enables direct measurement of differences of both impedance components (DL and DR). The instrument was designed to compare inductors from 100 mH to10 H in the frequency range from 100 Hz to10 kHz. The uncertainty of comparison in the impedance range from 1 W to 10 kW is assessed to be smaller than 10 ppm.
