Abstract :
The design and construction of inductive voltage dividers (IVDs) for use in impedance bridge applications in the 50 Hz to 1 MHz frequency range is described. Two dividers are described; one designed to operate from 50 Hz to 2 kHz and the other designed to operate from 2 kHz to 1 MHz. Preliminary comparison results of the new IVDs over the 100 Hz to 50 kHz frequency range are given. A new bridge to self-calibrate the IVDs is also described. The bridge is based on the straddling method and has been designed to characterize IVDs over the 50 Hz to 100 kHz frequency range.
