Purpose. Increasing connectivity and, as a result, reducing the time of receiving telemetry information on the distribution network section by means of the development of a hardware complex for monitoring and information transmission. Methodology. The research was carried out on the basis of system and elemental-structural approaches with elements of simulation modeling, programming and analytical calculations. Results. The results of the work are applied. Within the framework of the conducted research of the subject area, it has been suggested to use information and communication technologies to increase the level of operational response to emergency situations during the operation of electric transformer step-down substations. The parameters of the short-circuit current protection system have been calculated for the substation, based on the values of which a protection device with communication interface buses has been selected, which allow applying the approach of the Internet of Things, the Industrial Internet of Things, and the Internet of Energy for the subsequent construction of an automated information system. Hardware synthesis, selected means of automation and the given schemes allow further implementation of a full-fledged system of monitoring and control of the transformer substation. Scientific novelty. The concept of a universal system of information collection and transmission for distribution power systems has been proposed at the level of technical implementation. Practical significance. The paper offers a hardware data collection and transmission system that can be used in power systems for connection and telemetry of relay protection devices.
