Which electricity meter is better to put in the apartment: the classification of appliances

When looking for where to buy an electricity meter, it is important not to forget that the choice and purchase of an instrument should be made taking into account all factors. The device can not be returned and exchanged, if there are reasons that prevent its installation, because the sale of the sale is accompanied by the introduction of appropriate marks in the passport. This document contains the serial number, as well as the seal supplied by the state verifier.

Replacing the old electricity meter with a new device is performed in the following cases:

  • inconsistency of the instrument with the requirements put forward by the power company;
  • device breakage;
  • settling in a new living space.

Note! There is only one reason for the return of the electricity meter – the presence of a factory defect.

Instruments for counting electrical energy are classified according to the following criteria:

  1. Type of construction (mechanical type or induction and electronic).
  2. The number of phases (single and three phase).
  3. Type of measured energy (devices for measuring reactive, active energy, as well as universal).
  4. Tariff (one-, two-and multi-tariff).

Now such a problem as the replacement of electricity meters, at whose expense the installation of the device is of concern to many citizens, is particularly relevant. From a theoretical point of view, measuring devices are included in the area of ​​responsibility of the electricity supplier company. But in reality, the decision of the question falls on the shoulders of residents living in an apartment or in a private house, which the law requires to have a device for metering electricity, as well as its timely replacement in case of non-compliance with the requirements or serious damage.

There are more than 400 items of measuring equipment for electricity on the market. When the task is to buy an electric meter in the apartment, the price in this case is of secondary importance.

Electronic designs are complex devices whose main task is to convert the input signal into a digital data format. The result is reflected by a mechanical dial or screen.

Advantages of designs:

  • error in the testimony is very small;
  • functionality allows you to keep records in several tariffs;
  • The percentage of theft of electrical energy is very small.

Note! Electronic designs have additional functionality that allows you to buy an electricity meter with remote control, increased memory or built-in clock.

Disadvantages of electronic devices:

  • high sensitivity to sudden voltage drops in the network;
  • high price;
  • designs do not differ in special reliability concerning operation;
  • repair is very expensive.

The average price of electricity meters in this category is in the range of 900-3100 rubles. The cost depends on the design features of the device and the availability of additional functions, as well as the manufacturer. Before you decide to buy electric meters with a remote control, it is worth considering that the cost of devices with remote control is three times higher than that of standard devices.

Rates for meters with remote control (remote control):

Electromechanical devices are still found in old buildings of Soviet times. New generation devices are significantly modified, however, they use a similar operating principle. The design has the form of a plastic box, equipped with a viewing window. Through the glass, you can see the rotational movement of the disk and the accounting data for the consumption of electricity.

The counter is equipped with 2 coils, creating electromagnetic fields due to the passing voltage. Thanks to these magnetic fluxes, an aluminum disk is set in motion, which affects the wheels that display the numbers. The rotational speed of the disk in the old electricity meters, as in the new ones, depends on the volume of electricity consumption. This is displayed on the device indicators.

Note! Outdated induction devices gradually go out of circulation, although they are not without certain advantages.

Advantages of induction devices:

  • reliability in terms of operation, low failure rate;
  • unlimited terms of operation of electricity meters;
  • sudden voltage drops in the electrical network do not adversely affect the device;
  • affordable price.

This version of the design has drawbacks:

  • Significant errors often occur in the testimony;
  • devices are absolutely not insured against theft of electricity;
  • the device carries out an independent transfer of electricity readings (self-propelled accounting without the participation of consumers).

The cost of induction type electric meters varies in the range of 750-3300 rubles.

Pricing for induction accounting equipment:

On sale there are devices with one or three phases. It is necessary to buy a single-phase electric meter if the apartment is powered from a single-phase network consisting of 2 wires with a voltage level of 220 V. At the same time, the maximum allowable network load is 10 kW. This type of accounting equipment is most often used in private homes and city apartments.

Note! It is allowed to connect the device to a three-phase power grid, however, this will require 3 devices – a single-phase power meter for each phase.

The price of single-phase electricity meters is on average 870-2700 rubles.

If the house is powered by a network with 3 phases and a voltage of 380 V, it would be better to buy a three-phase electric meter. The need to use such powerful equipment is due to high energy consumption.

Most often from such networks eat:

  • apartment buildings;
  • small industries and factories;
  • workshops;
  • shield general purpose.

The average price of three-phase electricity meters is in the range of 2800-3300 rubles.

This type of equipment is used in the private sector, if devices with high power consumption are used:

  • three-phase electric motors;
  • electric boilers for heating;
  • welding machines and other specialized tools.

The operation of any accounting equipment is accompanied by some errors regarding the readings. From what class the meter belongs to, differences in its performance depend. Only a few percent deviation from the actual consumption is allowed.

Home appliances for apartments on average have a deviation of 2%. In practice, this is manifested as: if a consumer has consumed 100 kW of electricity, the data displayed by the meter will be in the range of 98-102 kW.

Note! The lower the accuracy value (class) in the technical passport of the device, the less errors occur when taking into account electricity. Such meters are much more expensive than others.

If you determine which electricity meters are better, starting from the error index, you should give preference to the 2nd class of devices. On sale there are devices of several varieties with different percentages of error:

  • 0.2–05%;
  • 2.5%;
  • 1-2%.

Features of the choice of devices according to the accuracy class

Electricity consumer Accuracy class Mains voltage class
Electricity producers 0.5 and above (units, complete with metering function by the hour and the ability to store information for 3 months.) With no restrictions
Apartment buildings 1.0 and above With no restrictions
Consumers with a power level of more than 670 kW 0.5 and above (units, complete with metering function by the hour and the ability to store information for 3 months.) With no restrictions
Individuals 2.0 and above With no restrictions
Consumers with a power level less than 670 kW 1.0 and above Up to 35 kW
0.5 and above More than 110 kW

With the advent of electronic devices on the market, the accounting system for consumed energy has changed significantly. Having completed the installation of an electric meter in an apartment, now it is possible to carry out accounting within several tariffs. Modern devices are able to support 2-3 tariffs, and some models – and more.

How much are electricity meters: prices of four-tariff devices:

Energomera CE 102M R5 145 J 253295 2320
EKF Skat 105E / 1-5 (60) TOI4 10501 2775

 

At the heart of the multi-tariff meter is a breakdown of accounting by time. For example, the calculation of energy consumption at the daily rate starts at 7.00 and ends at 23.00. The countdown of the night tariffing mode starts at 23.00 and ends at 7.00.

Helpful advice! The cost of electrical energy consumed during the day is significantly higher than at night. All energy-intensive costs, such as washing, can be scheduled at night to save.

The price of electricity meters day / night is much higher than the usual one-rate. But not all apartments have a significant difference between the cost of electricity during the day and night, so the cost of buying multi-tariff equipment may not pay off. Before buying, it is worth making calculations of expenses broken down by day / night and compare them with the results of a single tariff.

If the savings reach 35-50%, it is possible to safely replace the electric meter in the apartment with a multi-tariff one, if the difference is only 100-200 rubles, then such an acquisition would be inappropriate.

Devices of the modern generation are more perfect than the old models, because they are working on a fairly large amount of electrical energy, excluding the appearance of serious problems:

  • drops;
  • failures;
  • circuit and fire.

Requirements of Resolution 442 on the replacement of electricity meters

According to the updated Resolution No. 442, the rules for controlling the market for retail sales of electricity have been changed. The document prescribes that the transfer of readings of electricity meters used by citizens of the Russian Federation should be carried out using only electrical devices, and the minimum acceptable accuracy class of devices is 2.0.

Note! If the accuracy class of the device is less than the allowable value, the electricity meter should be replaced. Such a device can be used throughout the service life claimed for it or until a serious breakdown.

After the resolution No. 442 was issued, the service life of electricity meters correspond to the duration of the inspection interval – 6 years. This means that the non-conforming device can be used until the first check by the authorities, then it must be replaced. Today, the production of devices with an accuracy class below 2.0 stops. Also, repair is not allowed.

On the one hand, the procedure for changing the accounting equipment is designed to improve the safety of operating electricity, on the other hand, the question arises at whose expense the electricity meters are replaced. In view of Article 221, the replacement payment is made by the owner of the dwelling.

Which electricity meter is better to put in the apartment: choose the device

There are circumstances in which payment is made by the municipal service. This applies to those contracts obtained during the installation of electricity meters in the apartment, where there is a corresponding mark, otherwise the owner will cover all costs on his own.

Be sure to adhere to all safety rules, isolate all wire sections qualitatively and be extremely careful when performing each action. You also need to take care of obtaining the appropriate permission from the control authorities and have the necessary documents in place.
