description: This work is devoted to the analysis of a defective laboratory bench, modeling a virtual laboratory work on security in three-phase networks, comparing virtual laboratory work and real ones, their advantages and disadvantages. The tasks that were solved during the study: 1. Analysis of the educational laboratory stand acquired by SPbPU for the study of the risk of injury to a person by electric current in three-phase networks based on the theory of such networks. Revealing the discrepancy between the experimental and theoretical data during the operation of this stand. 2. Analysis of software and hardware systems and modern programming languages, in order to identify the main features, methods and tools for creating a virtual laboratory work. 3. Development of a virtual laboratory work on security in three-phase networks on the selected software and hardware complex or in modern programming languages, including the development of a methodological description for the laboratory work, which describes the steps for performing the laboratory practice using this software and hardware cycle.
