Project: Automated impedance metrology extending the quantum toolbox for electricity
Electrical impedance is used to manufacture passive electronic components, to analyse battery electrolytes, touchscreens and fuel gauges, and to calibrate dosimeters for radiation measurement. Currently, the lowest uncertainty impedance calibrations use previously defined ratios, with calibrations performed as a comparison with a known impedance. The ratio is normally defined by a purpose-built transformer and many different transformers are required for different impedance ratios. This project aims to replace this large number of individual standards by building a novel programmable impedance simulator. The project will produce new methods and devices to help establish a reliable impedance scale in the frequency range between 10 Hz and 20 kHz. New traceability routes will also be established where there are currently none, for example, impedance values for nanotechnology. This will bring the costs of impedance calibrations down, benefitting manufacturers of electrical components and users of electrical systems.
