Abstract
Calibrated inductive voltage dividers (IVDs) with the smallest possible uncertainties are required for the determination, maintenance, and dissemination of the ohm and the farad. An improved straddling method is described which uses triaxial guards to decrease systematic errors due to screen currents. The relative uncertainty with which IVD voltage ratios can be determined is calculated to be 1×10-9 (1 σ) at a frequency of 1592 Hz
