Abstract

The Physikalisch-Technische Bundesansalt (PTB) calibrates inductance standards in the frequency range from 100 Hz to 100 kHz and beyond. The relative uncertainties achieved range from less than 5×10^-5 to 5×10^-4 (2σ) depending on the frequency and the value of the standards. Because of the strong frequency dependence of the inductance standards it is of interest to use a suitable equivalent circuit to calculate the most accurate approximation for the frequency variation. A model is presented which allows the values of a GR1482 inductance standard to be calculated over the whole frequency range from 100 Hz to 100 kHz within the measurement uncertainties
