Installation of electricity meters is quite complex process. In order to have at least some idea of what requirements must be met for installing meters, we will talk about them in this article.
Since the electric meter is a complex metering device, it can be influenced by external factors, such as high humidity, temperature, aggressive chemical components in the air, vibrations, etc. These requirements are almost always met when the installation is carried out in an apartment; the only thing that needs to be taken into account is in this case- if the electricity meter is installed in public areas (on staircase, aisle, etc.), then it must be in a locked cabinet with a window at dial level.
Electricity meters must be installed in specially designated places - cabinets, niches, on panels. It is allowed to install meters on wooden or plastic boards that are rigidly fastened. Electricity meters should be installed at a height of 0.8 - 1.7 m, however, if urgently necessary, the installation height can be reduced to 0.4 m. Installation below this figure is prohibited.
It is worth paying attention to the fact that when electricity meters are installed in Moscow, the design of cabinets, drawers and niches should ensure ease of operation of the meter for service personnel. There should be easy access from the front side to the terminal box, as well as ease of installation and replacement of the meter.
Particular attention should be paid to the installation location of the meter in the case when is it necessary to install an electric meter in a garage?. If the garage is not heated, then you should pay attention to the choice of meter - there are special meters that are designed for installation in unheated rooms.
Also Special attention These factors should be taken into account when making installation of an electric meter in the country or installing an electric meter in Moscow within the Moscow Ring Road, of course, if someone constantly lives in the country winter time, and it is constantly heated, then there is no urgent need for this.
Work on installing electricity meters must be carried out by qualified workers who are authorized to work and have undergone special training. Before work is carried out, it is compiled (or changed) wiring diagram secondary circuits which will be connected to the electric meter. After an external inspection, during which the technician must make sure that all seals are present, the electric meter is connected.
The wire for installing the meter is selected in accordance with the power that will be consumed by the consumer. The maximum permissible wire cross-section is 10 mm2. In the case when technical specifications It is necessary to install a conductor of a larger cross-section; special lugs must be soldered to its ends, or the installation must be done using special adapter clamps. This is especially important in cases where it is necessary to install a common house electric meter, because the load can be quite high, and accordingly the cross-section of the wire will need to be selected appropriately.
It is worth paying attention to the installation location of switching equipment or fuses - they should be no further than 10 m from the meter. This is especially important when electricity meters are installed in private houses or garages, as well as when installed on poles and supports. In these cases, it is necessary to take this requirement into account and try to place circuit breakers or fuses as close as possible to the electric meter.
Who today can imagine existence in modern world without electricity? Few people, in fact. The electricity consumed by each must be measured. Therefore, you need to install a device that will help with this.
Which counter to install
There are electronic and induction meters; this division is based on functional principle. not so durable and accurate, so more and more consumers are replacing them with electronic ones.
There are also classifications that are based on the accuracy of the devices and the rated current. When the error is smaller, the measurement is more accurate. Meters with a rated voltage of 0.4 kV are usually selected for country houses where there is no powerful technology.
Electricity meter in a private home: what you need to consider when installing
An electrical installer with average qualifications can install the device. But there are installation rules and a number of documents that you need to acquire before this. A standard contract, for example, needs to be requested from the network provider; you also need a work assignment, which will contain an act of division of balance sheet ownership. This package of papers contains the requirements that the consumer must comply with in order for his home to be connected to the power grid. In addition, the documents differentiate the responsibilities of the home owner and the electricity supplier. It is precisely in this regard that it is recommended to install the electricity device inside the house in a heated distribution panel.
Installation of an electricity meter: list of requirements
It is best to install the device in a dressing room or hallway, so that in case of inspection or work with it there is access.
The input line must be de-energized in advance. This is done in agreement with the company’s electricians or network provider.
An interval of 0.8 - 1.7 m is optimal height, if fulfilled mounted installation electricity meter. The device is mounted horizontally on the surface.
First, the incoming electrical circuit must be connected to the circuit breaker, and then to the meter itself.
All electronics in the building must be secured. For this there must be a protective ground. If a phase imbalance occurs or it will be protection.
The general wiring for the whole house (usually a panel with automatic switches) is connected to the meter output.
If the consumer sees that the integrity of the seal has been compromised, an urgent need to call a representative of the network provider to reseal the meter.
The requirements of the PUE during installation must be adhered to.
It is important to do a test run.
Electricity meter in an apartment: what you need to take into account during installation
The rules for installing an electricity meter (PUE) contain everything important aspects, guided by them, representatives of the network company install devices in apartments.
Finding out the date is the first thing you need to do before you start installation. It should be on the seal. For 3-phase meters, the statute of limitations should not exceed one year, for single-phase meters - two.
Before connecting, contaminated Vaseline must be removed from the conductor and immediately reapplied thin layer Vaseline. The screws are tightened in two steps. The first one is tightened without jerking with the greatest permissible force, then the tightening is not completely, but is greatly weakened, then the secondary one is with normal force. This is how the electricity meter is installed. The price that representatives will ask you for service organization when self-installation, will consist only of the service for sealing the device.
The electrical meter terminal box, adapter box or test block must be subject to the sealing process. The voltage transformer chamber, as well as the disconnector drive handle, and again the clamp assembly are sealed if the meter was installed at a consumer substation.
The meter should be installed in compliance with all safety rules, including fire safety.
Installation of metering devices is the responsibility of the homeowner and is carried out at his expense.
To avoid fines and problems, you need to know the basic installation requirements and do everything correctly.
Technical requirements
You should follow the basic rules for installing electricity meters:
- The device must be installed in a place that is convenient for testing or Maintenance;
- During installation, the line must be de-energized; this should be ensured in advance by agreement with company representatives;
- the counter should be at a height of 80 to 170 cm from the floor;
- it is necessary to install a safety switch before connecting to the meter, before it;
- grounding is required;
- wiring (machines) are connected to the meter;
- if the integrity of the seals on the meter is broken, you must immediately call a specialist to seal it;
- After installation is complete, a test run is performed.
Where to install
When installing the meter outside, the following technical requirements must be observed:
- usually, if there are requirements from the provider company, the device is installed on the facade of the house at a height of 70 cm to 170 cm for ease of maintenance;
- It is also practiced to install a metering device at an appropriate height on a concrete pillar, and it must be located on the territory at home, and the wiring at the same time it is installed in the house itself.
The question of whether the requirement to move meters outside is legal is controversial. In fact, there are no regulations regulating the location of the meter.
The energy sales company motivates this by the fact that there should be easy access to the device for control purposes. However, in this case, no one is stopping them from installing a modern electronic device with a function in their house at their own expense. remote control readings and control at your own pleasure.
At the very least, these requirements are to the detriment of home owners and create inconvenience for them:
- If placed outside, the service life of the meter will be significantly reduced, since this device is not intended to operate indoors. extreme conditions, in the rain, in the cold, in the heat. At low temperatures readings may be incorrect.
- When installed on the street, the homeowner will have to put up with the fact that his meter has access not only to company employees, but also to everyone.
- Sometimes, to protect the instruments, they are installed at a height of 3 meters, which, to some extent, protects them from thieves, but the homeowner himself, without a ladder, will not be able to see his readings.
In fact, by forcing citizens to install meters on the street, they are deprived of the right to take care of the safety of their property, as provided for in the Civil Code of the Russian Federation.
This is beneficial for energy companies, as having the instruments outside makes it much easier for them to inspect and test the instruments, as well as take readings of energy consumption.
But this outer side problems, but the reverse is that it will be possible to control not only the readings of the device, but also the connection to the network up to the meter. That is, ultimately, to solve their pressing problems at the expense of homeowners, and on a massive scale.
Documentation
You can try to negotiate the location of the meter in advance, and if you guarantee employee access to the house to inspect and check the device, the problem will be solved. If not, then it still won’t work without a counter.
To perform the installation work, an average electrical qualification is sufficient; you can invite an electrical engineer yourself if the services of the company’s specialists are too expensive.
Specialist's note: Before starting work on installing an electric meter, you should obtain standard contract complete with the Certificate of division of balance sheet.
This is a necessary piece of paper that clearly states who is responsible for what, what the homeowner is responsible for and costs, and what will be the responsibility of the company. This document is necessary, especially if the meter will be located on the street.
If the installation will still be on the street, it is necessary to require a clear division of responsibility, which will be reflected in the contract.
Despite the growing popularity of electronic devices, they are also selling quite well.
Compared to modern ones, they do not require expensive maintenance and are definitely more reliable.
So far they have not been surpassed in reliability and ability to work and function without breakdowns. In Europe, where most of the meters are electronic, over time, they again began to show interest in unpretentious and reliable electromechanical devices.
In any case, no matter what device is chosen, you should make sure that the seal is intact and undamaged. There is also an expiration date for fillings:
- for single-phase – 2 years
- for three-phase – 1 year.
It is recommended to install the meter as close to the entry point as possible. The meter must be located in a warm room, this can be a heated or insulated hallway, where the company employees will have easy access to the device.
If the company requires that household meters be installed on the facade of the house, if it was not possible to get the requirement lifted, you can cheat a little and place the meter where the warm terrace will subsequently be built.
