Abstract: Electricity is a strategic industry that provides the necessary energy for production, household and other aspects of modern life. However, the increasing complexity and scale of energy systems requires the introduction of new technologies for effective control, management and monitoring of energy processes. It is in this context that telemechanical systems are a crucial tool for improving the automation and reliability of power grids [1]. The main purpose of using telemechanical systems in the field of electric power is not only to provide automated control, but also to create conditions for optimizing production processes, reducing energy consumption, and increasing the overall reliability of electric power systems. Also, one of the main tasks of these systems is the organization of quick and accurate recording of changes in certain parameters of the electrical network, the state of the equipment, which is ensured thanks to good automation of these processes. The USP-140 controller is designed to implement telemechanics functions in modern smart network systems. This device is used for status monitoring, control of objects and devices that interact with the power grid [1]. SPD-3.2 optical point smoke detector is designed to detect fires in closed rooms of various buildings and structures, which are accompanied by the formation of smoke. Its main task is to detect a possible threat of fire in time, to facilitate the prompt detection of a smoke signal and the transmission of the "FIRE" signal to the fire control device [2]. Magnetic contact detectors are used to protect protected objects from intruders and trespassers. A door opening detector, such as the Satel B-3 A, is designed to detect the opening or closing of doors or windows in a room [2]. The object of the research is ZTP-273-10 PJSC "LVIVOBLENERGO". The subject of the research is digital technologies and telemechanization of the transformer substation ZTP-273-10. The purpose of the study is the telemechanization of the transformer substation, as well as the description of the installed equipment and the formation of telemechanical signals. The master’s qualification work provides basic information about telemechanical systems, which include the purpose, types and functions of these systems, control, transmission, telemeasurement, telesignaling, and telecontrol systems. During the internship at the enterprise, work was carried out with the scheme in the SYNDIS RV software environment. A description of this software environment and corresponding illustrations are provided [5]. The operation of the scheme, the structural diagram of telemechanization, the list of signals of telesignaling, telecontrol and telemeasurement are considered [4].
