Abstrakt:	The present article considers the principles underlying the construction of modern standards for electrical units on the basis of quantum effects and fundamental constants. The study was carried out in accordance with the new definitions of the International System of Units. Along with a study of the methods used for constructing quantum sensing elements, the authors consider operational modes of the corresponding experimental setup. To that end, an experimental model of the standard was created. Software developed for this task is described along with the measurement procedure. It is demonstrated that the results obtained in the course of experimental studies are in good agreement with theoretical models. Conclusions are drawn about the possible use of the obtained results in the construction of new measurement standards. Tasks for future research are outlined. It is shown that the standards for electrical units on the basis of quantum effects and fundamental constants are used in the metrology of electrical measuring instruments. [ABSTRACT FROM AUTHOR]
