Abstract :
Application of ratio voltage or current transformers allows to use commercial digital LCR-meter as a comparator of two impedances. Advantages of such comparison method include the opportunity to increase the resolution up to 7-8 digits and the elimination of an error from nonlinearity of a meter.
