Thee paper analyzes the electric traction network and its features. The article shows that the use of one type of protection creates dead zones. To ensure reliability of the protection system, along with the maximum pulse protection system, digital terminal should be used.

This article discusses neural networks and artificial intelligence from the prospects for the future life of humanity. Neural networks and artificial intelligence are also presented as a tool for conducting almost all types of business, production, medicine (medical imaging). Neural networks perform the tasks of identifying objects of research, semantic segmentation, recognition of faces, recognition of parts of the human body, semantic determination of boundaries, highlighting objects of attention in the image and highlighting normals to the surface, automating and optimizing processes implemented in the format of manual labour. Prospects for the implementation of neural networks and artificial intelligence should be considered not as a substitute for a person, but rather as a support system for decision-making, in which the final choice is left to the person.

The article analyzes the existing protection systems for the traction substation-traction network –electric stock system, including digital terminals having several levels of digital protection used in the Russian Federation. Their vulnerabilities were described. Based on the analysis, a protection system responding to a number of signs of the transition process and having a built-in logic function used to select a mode was developed.

Today, encryption reflects a high level of reliability and confidentiality when working with data, both within local networks and in the global Internet network. At present, data processing has become an integral part of society. It penetrates practically the whole sphere of human activity. There are negative consequences of the development of this area. Very achievements in the field of high-tech technologies are used everywhere and are very new.
