Abstract
A solution to the problem of measuring a standard inductor in terms of the unit of capacitance using a stable ac two-phase generator is presented. Accurate separation of inductive and conductive components is obtained by means of a self-adjustment feature of the system, whose quadrature phase, in principle not essential for LC comparison, allows exclusion of any reference resistor. Standard deviations s < 1 × 10-6 and overall uncertainties near to 1 × 10-6 (1σ) are obtained with a test implementation of the system.Keywords
