Abstract
A comparison of methods used for the calibration of inductive voltage dividers at the National Bureau of Standards and the Physikalisch-Technische Bundesanstalt is presented in the frequency range between 10 kHz and 100 kHz. The error determinations performed on three transportable test dividers using two different calibration procedures agree well within the measurement uncertainty of ±3 × 10-7, making evident the lack of systematic errors in both methods.
