Documentation for any electrical installation includes a drawing of the grounding device (grounding), a precise description of all its parts and resistance calculated for specific operating conditions. Rules for the operation of electrical installations (PTEEP) require that a passport be issued for any grounding. What information is included in the ground loop passport, and how to fill it out correctly?
General information
Grounding is installed to protect people from electric shocks, and it also ensures the correct operation of electrical appliances. When they talk about a grounding device, they mean a grounding conductor and grounding conductors together. When installing a grounding mechanism, it is necessary to issue a passport.
The passport for the grounding device must include the following elements:
- date from which operation of the device began;
- listing technical characteristics and properties;
- results of inspection of the device condition;
- list of inspections and detected faults;
- executive scheme.
- information about repairs and those transformations that were made to the design.
Breaks and insufficient contact along the entire circuit between the electrical installation and the ground electrode must not be allowed. It is necessary to measure the electrical resistance of the structure and inspect its components. For this purpose, soil is lifted in different places and an inspection is carried out.
Grounding device passport form
The grounding passport has the status of the main regulatory document, therefore, when checking electrical installations by authorized bodies, it must be provided.
There is a special form for entering data - Form 24. When filling out the grounding device passport, indicate the name of the electrical installation and the start date of its operation.
If repair work was carried out, the date of its completion is noted.
The list of technical characteristics of grounding includes information about the material of the grounding electrodes, their quantity, size, and configuration. Vertical and horizontal grounding conductors are described separately. The depth of the connecting strips is indicated.
The passport must contain an executive grounding diagram. Make any changes related to repairs or replacement of parts. If changes occur in the design, these are also noted.
Data on the resistance of the soil and the grounding device is entered, and the method of connecting the elements is noted. Describe what kind of protective agent the joints are coated with (enamel, resin, etc.).
Entering test results
There is no single form for a grounding device passport. There is only a recommended sample. It can be changed at your discretion, but the basic data must be present in the document.
On the very first page (cover) they write the name of the object, followed by technical characteristics and a diagram. Then a table is presented in which the results of the inspections are entered.
Since ground electrodes are in close contact with the ground, corrosion resistance is important for them. Each time during inspection, special attention is paid to the degree of corrosion and the characteristics are entered into the table. The specialist inspecting the grounding writes his name on the form and signs it. Such entries in the passport are made every 6 months, in accordance with the requirements for verification periods.
The soil is selectively opened and... The passport also contains a table for this data. After checking the grounding circuit, a report is drawn up and attached to the passport. The frequency of such inspections is much less - once every 12 years.
You can read more about methods for monitoring grounding equipment in manual RD 153-34.0-20.525-00.
Portable model
This type of grounding is used to ensure safety when working on electrical equipment that is turned off. It is also used on those parts of the device through which current must flow, but it is turned off during work. Absolutely all portable devices strictly comply with GOST.
A passport is also issued for portable grounding. It contains information about the technical characteristics of the product, information about its acceptance and permission to operate, manufacturer’s warranties, as well as storage conditions and safety measures when handling the device. In essence, this document is similar to any other passport of an electrical product.
Lightning protection is a set of measures aimed at reducing the risk of damage or destruction of buildings and premises, transport infrastructure, communications, and technological equipment from the effects of atmospheric electricity. In this article we will tell you how the Ministry of Health works and how to obtain a passport for it.
From this article you will learn:
What is and why lightning protection and grounding are needed
Atmospheric electricity is dangerous because of its unpredictability. Up to 16 million thunderstorms occur annually on the globe, that is, about 44 thousand per day. As a result of a direct lightning strike, destruction of buildings, fires, and death of people located at these facilities or in dangerous proximity can occur. This may also result in equipment failure or damage.
The lightning discharge at the point of breakdown is approximately 30 kV per 1 cm. Lightning always hits the place where it is easier for charged electrons to spread. Therefore, the metal tip of the lightning rod will accumulate lightning discharges, for which this is the easiest way.
The most lightning-dangerous period of the year in the Russian Federation is the summer season, mainly July. As a rule, thunderstorms are most frequent in July, as the height of the clouds increases to 12-14 km above the ground, and because of this, the charge between them increases.
Types of lightning protection
Lightning protection devices (LPDs) are a way to protect infrastructure facilities that are designed to neutralize lightning discharges.
The lightning discharges that we see in the window are already the reverse stroke of lightning. The structure of the MH resembles a ring. A direct strike is a direct contact of a lightning channel with a building or structure, accompanied by the flow of current through it.
There is also a secondary damage associated with the induction of potentials on metal structural elements, equipment, in open metal circuits, caused by nearby lightning discharges and creating the danger of sparking inside the protected object.
The introduction of high potential is the transfer into a protected building or structure through long metal communications (underground, above-ground and above-ground pipelines, cables, etc.) of electrical potentials that arise during direct and close lightning strikes and create the danger of sparking inside the protected object.
Lightning protection device
MH is divided into external and internal. External is an elementary type of protection against electrical discharge during a thunderstorm and is designed to intercept lightning and safely lead it to the ground. Thus, at the moment of a direct strike on an object, the lightning protection system must take on the full force of the lightning discharge current and divert it through down conductors into the grounding circuit, where the energy will safely spread in the ground.
Lightning protection project
An important task when designing a facility is the informed choice of the MH system. This is an important part of the construction project from the point of view of the environment, the preservation of buildings and structures, life support facilities and industrial communications from the effects of atmospheric electricity.
It should be noted that in Russia there are standards for the categorization of protected objects and the effectiveness of lightning protection measures.
When designing, the guidelines used are given in:
- RD 34.21.122-87,
- SO 153 – 34.21.122 – 2003,
- GOST R IEC 62305-1-2010,
Equipment
External MH consists of:
- lightning rod,
- lightning rod (down conductor),
- horizontal ground loop,
- deep rod grounding.
Installation of lightning protection
The following requirements apply to the installation of the PUE grounding loop:
- Accessible location of grounding conductors for visual inspection once every six months during the periods of greatest and least freezing of the soil (hot and cold seasons), as well as for opening the soil at least once every 12 years.
- Strength of connecting elements - the deep rod grounding conductor must be securely attached with a bolted or welded connection to the horizontal grounding loop. The ground electrode should not come out of the ground, since in this case the lightning discharge current will not spread inside the soil, a reverse transformation will occur, the consequences of which will be catastrophic for the MZ facility.
- The level of reliability of devices that act as fuses.
- Measurement of grounding elements. The measurement must be carried out by accredited electrical laboratories. The insulation resistance measurement protocol is always .
To prepare for installation, it is necessary to establish the dimensions of the building and the materials used in the structures, determine the installation locations for grounding, the descent of down conductors from lightning rods to the grounding loop, as well as the installation of lightning rods. Then the required number of down conductors, lightning rods, grounding conductors, auxiliary elements - holders and fasteners - is calculated.
Installation includes the following sequence of operations:
- installation of holders;
- installation of lightning rods and laying of current conductors;
- installation of grounding (laying a circuit of metal strips or rods into a trench around the building).
Attention
After installation, it is imperative to check the grounding resistance, which should not exceed 15 Ohms. Then the ground loop will be connected to the common ground loop of the electrical installations in the building.
Active lightning protection
In addition to traditional external systems, active MH – an installation with a proactive streamer emission system – has now become widespread.
The principle of operation is based on anticipating a lightning strike by forming its own artificial streamer, which is directed towards the lightning leader. This effect can be achieved, for example, by installing a parallel chain of capacitors and arresters.
If the lightning leader approaches such a lightning rod, the electric field strength will increase and the spark gaps will breakdown, resulting in a spark discharge. The air around is ionized, which contributes to the appearance of ascending streamers, and ahead of the approach of the descending leader. This advance interval is the main characteristic of the installation and is indicated in its passport.
This is how an active system works in general terms. Manufacturers claim that the protective zone of such devices significantly exceeds the traditional external MH system (Franklin rod). However, at present there is no reliable evidence of the greater effectiveness of this system over the traditional one.
Internal lightning protection system
In addition to the external one, which is essentially an elementary Franklin rod, there is also an internal MZ, which is a complex of protective devices against surge voltages - resistors and inductors. In no case does it replace the external one. The purpose of the SPD is to protect expensive network equipment. SPDs are divided into three types.
It is known that there are direct and indirect lightning strikes. Direct - lightning strikes a building or the communication or power line supports connected to it. Indirect – occurs due to lightning strikes near communication lines.
Type 1 impulse overvoltage from a direct shock. It is usually installed in rural areas with overhead power or communication lines, in buildings with lightning rods or located near high-rise objects (mobile communication towers, tall trees, etc.).
Type 2 impulse overvoltage from an indirect shock. In this case, the stored energy is approximately 17 times less than the energy of a direct impact.
Type 3, for its survivability, requires the use of types 1 and 2 in front of itself and is installed directly next to the consumer. It could be, for example, a regular UPS-type surge protector or a voltage stabilizer.
Lightning protection passport - sample
The passport is handed over to the owner of the protection object after installation of the lightning protection device. It contains a title page, inspection and verification protocols, as well as a diagram indicating measurement control points.

Our objects
A lightning protection passport is a document that is drawn up by the parties after the installation of a facility’s lightning protection system in order to confirm its compliance with safety standards and subsequent protection of the customer in the event of claims (controversial issues) from fire safety supervisory authorities. The installation company provides guarantees that indicate the parameters of the object, as well as its specifics. Work is underway to strengthen and ground the positions. All this is formalized and then transferred directly to the customer. All data and indicators that were available at the time of the inspection are entered into the protocol. It is evidence that the operation of the facility is absolutely safe.
Guarantees provided by the lightning protection passport
A lightning protection certificate is issued during the acceptance of work. Before this, specialists inspect not only the object itself, but also the surrounding area. Only representatives of the relevant authorities or specialized companies can carry out such work.
Certification is carried out during test work during the commissioning of the building (structure). It repeats after a certain period of time. The exact deadlines must be indicated in the document issued. It will guarantee that everything is in order with the house (or any other object), and in the event of a lightning strike, the building will be reliably protected.
Drawing up an act implies mutual responsibility, because a deliberate violation of its terms can lead to problems.
An annex is also added to the passport document, which will contain detailed instructions in case of unforeseen situations. Lightning protection is provided by the following devices:
- down conductor;
- lightning rod;
- grounding element.
The operating principle is as follows: the lightning rod intercepts. The down conductor then helps to remove the lightning charge, after which the ground electrode connects it directly to the ground. The charge fades and is no longer dangerous. All parts of the system must be properly connected to each other.
Advantages of a grounding passport
A building's lightning protection certificate has a number of advantages:
- guarantees client safety;
- insures against potential threats (lightning);
- makes the structure resistant to external influences.
Now it is required by many representatives of government services (fire department, gas inspectorate). The document is filled out in several copies at once. This is necessary so that all parties can control the process. A sample form can be found on our official website. There you can familiarize yourself with all the points of the form.
If you do not draw up such documents, then there is a high probability that you may be injured during a thunderstorm.
Lightning protection is provided not only for residential but also for industrial facilities. This rule is established in accordance with GOST. The correct choice of category, as well as proper installation of all systems will ensure reliable protection even during serious disasters. A high-quality electrical installation will prevent all sorts of problems. Every year, thousands of people around the world become victims of the elements, where ball lightning also poses an increasing danger.
A person must understand that in the absence of the necessary lightning protection devices, he exposes himself to great risk. Many buildings have not met modern safety requirements for a long time, so we are actually living on a powder keg. If you do not check for a long time, the risk of being struck by lightning increases. Net neutral can also fail. Its inspection is carried out exclusively by professionals.
The passport contains evidence that the company can carry out such work, as well as a document stating that the devices meet all modern requirements. An example of filling it out can be seen on our website, where you can also fill out lightning protection, which will make your life safer.
