About the project

Yuri Kharechko’s blog on the LiveJournal platform is a specialized resource dedicated to the basics of electrical installations in buildings and issues of protection against electric shock. The project is positioned as material for advanced training of specialists in this field. The author's style combines technical rigor with critical analysis of the regulatory framework.

The site is actively working to clarify complex technical issues. In particular, the author is not afraid to enter into controversy with official sources if he sees errors in them. A striking example is the analysis of misinformation in the article Nullification on Wikipedia or a harsh reaction to comments that criticize the work of boards that create PUE with gross errors.

Main directions

The blog content is focused on practical aspects of electrical safety and the implementation of various grounding systems. The main topics of publications include:

• Analysis of errors in encyclopedias and standards. The author publishes brief analyzes of inaccuracies, for example, in Wikipedia articles or in comments to his materials in Zen.
• TN-S, TN-C-S and TT grounding systems. The construction of protective conductor circuits for these types of systems is discussed in detail.
• New standards. Particular attention is paid to GOST R 586982019 (IEC 61140:2016), which introduced new general provisions for electrical installations and equipment.
• IT system. The issues of implementing part of the electrical installation of a building with the IT grounding type are considered, which is relevant for medical institutions. It also describes how to combine different types of grounding (TN-C-S and IT) in one building.
• Connection to a common network. There are materials on how to implement TN-C, TN-C-S and TT systems when they are connected to the same electrical distribution network.

Features of the site

The project is characterized by a high density of technical information. There is no water or general reasoning here - only specifics on dates, GOST numbers and links to real articles. The blog archive is structured by publication periods, which makes it easy to find material for a specific year.

An interesting feature of the resource is its interdisciplinarity. The author actively uses the Yandex platform. Zen to promote his ideas, and then brings the audience back to the blog for a detailed analysis. This creates a closed loop of discussion where user comments and questions become part of a professional discussion.

Statistics show that the project has a stable audience: more than 3 thousand readers and hundreds of subscribers. This suggests that the topic is really in demand among specialists who want to understand the nuances of electrical safety.
