Subject of study. This article presents the results of a study of the possibilities of using the interference of polarized rays in the creation of an optical current meter. The interference optical current meter is proposed, its structure and operating principle are described in details. The development relates to optical polarization devices, in which the magneto-optical Faraday effect is used to measure alternating current in high-voltage power networks. The aim of study is the development of the interference method for measuring current in high-voltage power networks and the development of interferometric optical current meter free from the defects of known devices. Method. The modeling of the proposed device and theoretical studies of the work of a system, including polarizers, a Wollaston prism by means of vector algebra, were used in this work. Main results. The interference method for current measurement was developed. The combination of distinctive design and output signal processing features made it possible to create a simple compact interference optical current meter, which is free from the shortcomings in contrast to known devices that also solve the measurement task of current in high-voltage power networks. Practical significance. The current meter can be used as a basic device when creating a series of alternating-current meters for electrical high-voltage power networks of various classes working in commercial electricity metering, as well as in automation systems of various power plants and low-voltage equipment.
