Pue 7 year of release. PUE (last edition)

Hello, dear visitors and readers of the Electrician's Notes website.

In many articles published on the pages of this site, I often refer to regulatory technical documents, such as PUE, PTEEP, POT R M-016 and others. I do this in order to prove to the reader that all the requirements are not invented by me out of my head, but are taken strictly from regulatory documents.

PUE (Electrical Installation Rules) is the main regulatory white paper(NTD), which is used by design engineers when creating electrical installations of all modifications and types. If to speak in simple words, then the PUE are the rules that describe electrical devices and the principles of their construction, as well as the basic requirements of individual systems, nodes, elements and communications of the power system.

Let me remind you that the PUE apply to newly constructed and reconstructed electrical installations of direct and alternating current with a voltage of up to 750 (kV), including special electrical installations.

Attention! Currently in the territory Russian Federation the PUE is valid in the form of separate sections and chapters of the 7th edition and the current sections and chapters of the 6th edition.

As for the countries of the former Commonwealth of Independent States (CIS), the 6th edition of the EMP is still in force there, which is now considered to be somewhat outdated.

I’ll tell you a little about the history of the creation and development of the PUE.

History of PUE (Electrical Installation Rules)

PUE has been in existence for over 50 years. Its publications are constantly supplemented and revised to this day, because there is a constant development of technology and technology, which requires more stringent requirements for electrical safety and reliability of electrical installations.

For example, PUE 5 editions were published in the period from 1976 to 1982 in separate sections. PUE 6 edition was developed and put into effect by the Ministry of Energy and Electrification of the USSR on June 1, 1985.

In the period from 1999 to 2003, individual chapters and sections of the new PUE 7th edition were developed taking into account modern GOSTs, SNiPs and recommendations of working groups.

For example, Chapters 4.1 and 4.2 of the EMP of the 7th edition were approved by order of the Ministry of Energy of the Russian Federation on 06/20/2003 and entered into force on 11/01/2003.

At my workplace there is a general edition of PUE-6, as well as newly introduced sections and chapters of PUE-7 in the form of separate brochures.

What is the difference between the PUE of the 7th edition and the PUE of the 6th edition?

The sections and chapters of PUE-7 released into the light have tightened the requirements for electrical safety, which have become practically compliant international standards and norms. Some concepts have also been introduced:

  • IT earthing system
  • protective grounding (instead of the concept of grounding)
  • etc.

I would also like to say that PUE-7 does not take into account the requirements for the protection of electrical installations from fires in accordance with GOST R 50571.17-2000, from overvoltages during ground faults in electrical installations above 1000 (V), from switching and lightning surges and discharges in accordance with GOST R 50571.19-2000, GOST R 50571.18-2000 and GOST R 50571.20-2000.

Thus, the PUE of the 7th edition is not the last edition, but will also be supplemented in the future.

PUE 7 edition download

Dear readers and guests of the site "Electrician's Notes", I suggest you download the current editions of PUE-6 and PUE-7 completely free of charge in in electronic format which I personally use.

I like the electronic version of the PUE (Electrical Installation Rules) because it conveniently, clearly and systematically breaks down all its sections and chapters. I would like to note that in the electronic version of the EMP are laid out in the form of a general publication, i.e. as current chapters from the 6th edition and introduced chapters from the 7th edition.

Another plus of the electronic edition of the PUE is the presence of active links to related clauses of the rules.

If you do not need an electronic edition, then I suggest downloading the PUE in .pdf or .doc formats.

Rules for the installation of electrical installations (PUE) is the main regulatory and technical document that designers are guided by when calculating electrical installations of all types and modifications.

In other words, PUE are rules that describe the principles for constructing electrical devices, as well as the basic requirements for power systems, electrical components, elements and communications.

In fact, the PUE is the Bible and the main reference book for any qualified electrician. If a master comes to you who does not know what the Electrical Installation Rules are, this is not an electrician. Hit him in the neck.

The rules described in the PUE apply to newly constructed or reconstructed electrical installations of direct and alternating current with a voltage of up to 750 (kV), including special electrical installations.

Currently, the PUE operates on the territory of the Russian Federation in the form of separate sections and chapters of the 7th edition and the current sections and chapters of the 6th edition.

The history of the creation of the Rules

PUE has existed for over 65 years (the first edition was published back in 1949). Due to the constant development of technology, the emergence of new technologies, the increasing requirements for electrical safety and reliability of electrical installations, these rules are continuously supplemented and revised.

For example, the fifth edition was published between 1976 and 1982 in separate sections. PUE 6 was developed and put into effect by the USSR Ministry of Energy and Electrification on June 1, 1985, and most of it is still in effect today.

Gradually, the obsolete chapters of PUE 6 are being replaced with the corresponding chapters of PUE 7, as they are developed taking into account the most modern GOSTs, SNiPs and recommendations of working groups. Thus, the 6th edition of the PUE is still valid, with the exception of some obsolete chapters (see their list below).

In the period from 2000 to 2003, the following chapters of PUE 6 became invalid (and, accordingly, chapters of PUE 7 came into force):

  • July 1, 2000 - section 6 in its entirety, as well as chapters 7.1, 7.2;
  • January 1, 2003 - chapters 1.1, 1.2, 1.7, 7.5, 7.6;
  • September 1, 2003 - chapter 1.8;
  • October 1, 2003 - chapters 2.4, 2.5;
  • November 1, 2003 - chapters 4.1, 4.2.

What is the difference between the PUE of the 7th edition and PUE 6?

The sections and chapters of PUE-7 released into the light have tightened the requirements for electrical safety, which have become practically in line with international standards and norms. Some concepts have also been introduced, for example:

  • grounding system TN-S;
  • grounding system TN-С-S;
  • grounding system TN-C;
  • TT grounding system;
  • IT grounding system;
  • protective grounding came to replace the concept of zeroing;
  • etc.

I would like to note that PUE-7 still does not take into account the requirements for the protection of electrical installations from fires in accordance with GOST R 50571.17-2000, from overvoltages during ground faults in electrical installations above 1000 (V), from switching and lightning overvoltages and discharges in accordance with GOST R 50571.19-2000, GOST R 50571.18-2000 and GOST R 50571.20-2000. Thus, it is obvious that PUE 7 is not a complete edition, and will be supplemented in the future.

Our website presents, consisting of the PUE of the 6th edition with all the chapters from the 7th edition that have entered into force. Thus, this is the most complete and most up-to-date version of the Electrical Installation Rules subject to all official changes and additions.

Also you can (PDF, 3 Mb) in order to print it on paper.

The rules for the installation of electrical installations contain a set of requirements for the design, placement, maintenance, operation and repair of electrical installations. In the article you can read and download the full text of the PUE in the 7th edition.

What is established by the Rules for the installation of electrical installations

PUE-7 is a revised 6th edition. The Rules establish requirements for electrical networks and equipment both for outdoor use and inside buildings or advertising structures.

The 7th edition contains general electrical power supply, test standards, and protection and insulation. The second section is devoted to the transmission of electricity through overhead lines. We are talking about power lines with voltage up to 1 kV and above. Not only descriptions of the types of overhead lines are given, but also the procedure for calculating their parameters.

The fourth section regulates the operation of substations and switchgear, the sixth - electric lighting and lighting fixtures for outdoor and indoor use, advertising structures.

The seventh section establishes the rules for the use of electrical equipment of special installations. These include, for example:

  • elevators;
  • water installations;
  • electrical components of fire alarms;
  • power equipment and more.

PUE establish the materials from which certain devices should be made, the cross-section of cables for certain loads. It also provides formulas for calculating loads, describes the possibility of using specific equipment in specific environmental parameters (temperature, humidity) or climatic conditions.

Classification of premises for electrical safety

  • premises without increased danger;
  • premises with increased danger;
  • areas are especially dangerous.

In rooms without increased danger, optimal conditions are maintained for the operation of equipment and electrical networks. They do not have the conditions characteristic of groups 2 and 3.

Hazardous premises are subject to one of the following conditions:

  • humidity from 60 to 70% or dust capable of conducting current;
  • floors made of metal, reinforced concrete, brick or earthen (conductive);
  • high temperature inside;
  • the probability for a person to grasp with one hand the grounded metal structures of the building, machines, equipment, and the other for the bare parts of electrical equipment.

Especially dangerous premises for electrical safety are characterized by at least one of the following parameters:

  • humidity about 100%;
  • organically or chemically active environment;
  • two or more conditions from the second group at the same time.

Electrical installations located outdoors (on the street) are equated to especially dangerous premises. It's connected with .

General instructions for electrical installations

All equipment, products and materials used in electrical installations (hereinafter - EU) must undergo mandatory certification in accordance with state standards(GOST) or technical conditions (TU). When designing electrical installations and selecting components, it is necessary to take into account the conditions of future operation.

The surrounding infrastructure (heating, air conditioning, water supply, etc.) must be arranged in accordance with the SNiP and the requirements of the latest version of the PUE, and the power plants themselves should not be applied.

In the presence of factors contributing to pollution (electromagnetic, noise, vibration, etc.), the construction of protective structures is required to neutralize the harmful effects. In addition, it is necessary to organize the disposal of waste.

When designing a power plant in accordance with the rules for the installation of electrical installations PUE - 7th edition, it is necessary to take into account the economic feasibility and the need to use advanced technologies and materials that reduce resource consumption.

All elements and cables of the same type must be uniformly designated in accordance with GOST R 50462 with letters or colors. All power plants must be fenced, and the fences must have the necessary strength. In public premises, solid fences are used, in specialized ones, without access by outsiders, mesh or non-continuous fences are allowed. Newly commissioned installations, new or after reconstruction, must be subjected to acceptance tests.

Scope of PUE

The PUE defines an electrical installation. This is a complex of lines, devices, machines, as well as auxiliary equipment designed to receive, redistribute, convert electricity. This complex includes not only machinery and equipment, but also the premises in which they are located (in the case of closed installations).

In addition to closed electrical installations located indoors, open or outdoor ones are also distinguished. They, in turn, are either not protected from the environment at all or are fenced with a mesh fence or canopies (clause 1.1.4 of the EMP). The open ones include power lines, street transformers, etc.

In turn, electrical facilities are divided into:

  • dry (humidity< 60%);
  • wet (humidity 60-70%);
  • raw (moisture > 75%);
  • especially raw (humidity about 100%);
  • hot (ambient temperature > 35 ° C constantly or periodically (more than 1 day));
  • dusty;
  • with a chemically or organically active medium.

The rules in question apply to new electrical installations or installations in the process of reconstruction. Moreover, direct and alternating current in them should not exceed 750 kV.

A separate section of the Rules is dedicated to the operation of electrical installations special purpose. If the installation is not described in section 7, then its device is regulated by another normative act. However, the use of PUE is possible for such devices if they are similar to those described in the publication.

The applicability of the Rules to already operating facilities is determined by the possibility of increasing their efficiency and reliability during further operation. As for the objects of reconstruction, the Rules apply only to those parts that are subject to reconstruction.

What changes have been made to the Electrical Code, edition 7

The 7th edition of the PUE is a revised sections and individual chapters of the sixth edition. Those chapters that are not revised remained in the 6th edition and are still used in this edition. Therefore, in the 7th edition, for example, there are no sections 3 and 5.

Edited chapters have been contributed to the 7th edition for 17 years. Thus, Sections 6 (Chapters 6.1-6.6) and 7 (Chapters 7.1 and 7.2) were the first to be revised. They were approved by Order of the Minister of Fuel and Energy of the Russian Federation dated October 6, 1999 No.

The remaining sections began to apply in 2003, but they were approved in different time and different commands:

  • Chapters 1.1, 1.2, 1.7, 1.9, 7.5, 7.6, 7.10 - by Order of the Ministry of Energy of the Russian Federation of July 8, 2002 No. 204;
  • Chapter 1.8 - Order of the Ministry of Energy of the Russian Federation dated April 9, 2003 No. 150;
  • Chapters 2.4 and 2.5 - by Order of the Ministry of Energy of the Russian Federation dated 20.05.2003 No. 187;
  • Chapters 4.1 and 4.2 - by Order of the Ministry of Energy of the Russian Federation dated 06/20/2002 No. 242.
