Installation of an electricity meter in a house, on the street or in an apartment: rules and requirements

Who today can imagine existence in the modern world without electricity? Very few people, in fact. Consumed by each electric power needs to be measured. Therefore, you need to perform the installation of a device that will help in this.

What counter should I set?

Counters are electronic and induction, this unit is based on a functional principle. Induction counters are not so strong and accurate, therefore more and more consumers replace them with electronic ones.

Still there are classifications, which are based on the accuracy of the devices and the rated current. When the error is smaller, the measurement is more accurate. Counters with a rated voltage of 0.4 kV are usually selected for country houses where there is no powerful equipment.

Electricity meter in a private house: what you need to consider when installing

An electrician with an average qualification is able to install the device. But there are rules for installing an electricity meter and a number of documents that you need to acquire before that. A typical contract, for example, you need to request from a network provider, you also need a job assignment, in which there will be an act of separation of the balance sheet. This package of securities contains those requirements, which must be observed by the consumer in order for his house to become connected to the power grid. In addition, the documents demarcate the responsibility of the owner of the house and the electricity supplier. It is precisely in this connection that it is recommended to install an electric power device inside the house in a distributive heated shield.

Installing an electricity meter: a list of requirements

It is best to install the device in a dressing room, a hallway, so that in case of checking or working with it there was access.

The input line must be de-energized beforehand. This is done in consultation with the company's electricians or with a network provider.

The interval 0.8 - 1.7 m is the optimal height, if the hinged installation of the electricity meter is performed. The device is mounted horizontally on the surface.

First, the incoming electricity circuit must be connected to the automatic safety switch, and then to the meter itself.

All the electronics in the building need to be secured. For this, there must be a protective earth. If a phase skew or a short circuit occurs , it will be a protection.

Connection of the general wiring to the whole house (usually a shield with automatic machines) is made to the output of the meter.

If the consumer saw that the integrity of the seal was broken, you urgently need to call a representative of the network provider, so that he resets the counter.

The requirements of the electrical installation during installation must be adhered to.

It is important to make a test inclusion.

Electricity meter in the apartment: what needs to be taken into account during installation

The rules for installing the electricity meter (PUE) contain all the important aspects, guided by them, the representatives of the network company make installation of the apparatus in the apartments.

Find out the date - that's what you need to do first thing before starting the installation. She must stand on the seal. For 3-phase meters, the limitation period should not exceed one year, for single-phase meters, two.

Distribution boards located on the areas of apartments - a traditional place for installation of mechanisms. If they are still installed right in the living room, where the input is located, then it should be a special closed flap in the hallway or in the corridor. They also set up a group of automatic machines for the whole apartment.

The basic requirements that must be met when installing

It is necessary to prepare a place where the installation of an electric switchboard and the installation of an electricity meter with automatic devices will be carried out.

After agreeing with the company's electrical installers or the network provider, it is necessary to de-energize the input line.

We prepare a place for the installation of an electric switchboard with a counter and automatic machines.

It is necessary to disconnect the input line from the voltage. This can be agreed with the representatives of the wiring company.

Do not forget about the grounding, which in case of phase distortion allows you to secure all electrical equipment in the room.

First, the input current circuit must be connected to an automatic safety switch, then to the counter.

It is necessary to connect the output of the device to the introductory machine or their group.

A test inclusion is in progress.

Installing an outdoor meter

Often, these aperatures are installed in the open air, and not in the room itself, but this should also be done in accordance with a number of technical and operational requirements.

The best option is to install an electricity meter on the facade at a height of 0.8 to 1.7 meters, which will enable representatives of the network company or service maintenance to get free access to the device. It is also better to install a safety device on this electrical switchboard.

Setting the counter on the pole

There are a number of uncomfortable moments for servicing devices mounted at altitude. Although, on the other hand, the installation of an electricity meter on a pole excludes the possibility of theft of current, which is a big plus.

The inconvenience that arises first of all is the inaccessibility of the device when it is necessary to read its readings. To see its display, you need to climb on some support, etc. In principle, it is possible to use an electricity metering system that operates in an automatic mode, such as, for example, SOUP 04. It makes it possible to read meter readings remotely from the unit on any poles. The installation of the electricity meter on the pole is the cheapest, and it is the least expensive for materials.

The basic requirements for installing a counter on the street

Taking into account the rules of the SAE, you must disconnect the network line before proceeding with the installation.

The interval of 0.8 - 1.7 meters is the ideal height for the mounted installation.

The electrical flap must be heated. Since at a temperature of -5 ° C the electric meter can start to give incorrect readings.

First, the input current circuit must be connected to an automatic safety switch, then to the meter.

Protective earthing will protect the electronics in the event of phase failure or short circuit.

It is necessary to connect the counter output to the introductory machine or their group.

A test inclusion is in progress.

Features of two-tariff system

The installation of a two-tariff electricity meter is due to the fact that various records of consumed electricity are maintained. Alas, few even know this. Such a system is differentiated by time of day, so we pay for energy consumption at night - from 23:00 to 7:00 - pay at a price four times less than in the daytime.

This is due to the fact that there are two main operating modes of power plants - peak and low. In the morning hours from 7 to 10 the maximum power consumption is observed. It is during this period that the work of many enterprises begins. Also, the maximum falls on the evening hours - from 19 to 23, when people come home. A sharp decrease in the level of electricity consumption is observed at night. The unstable rhythm of work has a bad effect on the life of equipment in power plants. With a uniform load, the consumption of resources - coal, gas, and oil - is also reduced. If you align the operation mode of the stations, you can save them.

The cost of installing an energy meter with multi-tariff accounting will pay off over time, as it will be possible to pay only 40% of the price for each kWh per night, that is, savings of up to 60%. Conveniently, the fact that many models provide the ability to monitor the statistics of the load, current, see the graphics. Since such counters are equipped with a "current loop" interface, they have a pulse output, and also have an event log.

To transfer the user to a multi-tariff tariff, you must first contact the energy supplier - in the city or district power network, apply for the installation of this unit. After receiving a response to the application with permission to switch to a new tariff, you can perform the installation of a new device, and then renew with an organization the contract for the supply of electricity under the new tariffs.

Who should install electricity meters?

Since settlement machines are the property of an energy sales organization (usually), then their specialists must install them. They also seal the counter. The consumer is only responsible for its storage and use.

Self-Installing the Counter

The consumer who made the decision to install this device on his own, should know that he takes full responsibility for himself. The installation of an electric power meter by one's own hands is not too complicated. The main thing that must be considered and must adhere to - the rules of electrical safety.

When the wiring is installed under the meter, the ends of the wires near them must have a length of at least 12 centimeters.

The neutral wire at a distance of 10 centimeters in front of the device must have insulation or a shell of a different color. If aluminum wires are connected to the meter, it is important that the conductor's surface is cleaned with a steel brush (can be a file) and covered with a layer of special neutral technical petroleum jelly.

Before connecting, the contaminated petrolatum should be removed from the conductor and immediately applied again a thin layer of petroleum jelly. The screws are tightened in two steps. The first - is tightened without jerks with the greatest permissible effort, then the tightening is not complete, but greatly weakened, followed by a secondary one - with a normal force. And the installation of the electricity meter is carried out. The price that representatives of the service organization will request from you in case of self-installation will consist only of the service for sealing the device.

The clamping box of the elecro-counter, the junction box or the test block - are necessarily subject to the sealing process. The chamber of the voltage transformer, as well as the handle of the disconnector drive, again the assembly of the clips is sealed in the event that the installation of the settlement meter was carried out at the substation of the consumer.
