According to the regulations, the lifetime of the electricity meter is limited by the failure of the device or the end date of the intertesting interval, which is 16 years. After that, the metrology service gives a conclusion about the possibility of using the device in the future.

Currently, the bodies of the State Energy Supervision Authority are installing new equipment, even if the replacement time of electric meters is far from the end date of verification. Such a decision is regulated by the Decree of the Government of the Russian Federation of May 4, 2012 under the number 422, according to which the account of the amount of energy used should be performed by devices of accuracy not lower than class 2.Replacement of faulty instruments or electricity meters with the service life left is carried out at the expense of the owner of the residential premises( Article 210 of the Civil Code of the Russian Federation).

Types of counters for the calculation of electrical energy

Currently, the count of the amount of electricity consumed is counters:

• induction type;
• electronic devices.

Induction meters use the principle of magnetic induction, thanks to which current-carrying coils with their electromagnetic field act on a movable metal disk. According to the number of his turns, the amount of energy spent is judged. The expiration date of such electric meters is limited, since their design provides for the presence of moving parts.

Modern electronic meters do not suffer from this drawback, since they record electricity on the basis of pulses generated by discrete elements when electric current is applied to them. Thanks to the elemental base of such electric meters, their shelf life is virtually unlimited, and in addition, modern electronic stuffing provides ample opportunities for automation of accounting.

Tariffs for used electrical energy

It is not a secret for anyone that the cost of electricity at night is several times different from the daily price. Depending on whether a constant tariff is used or the cost of energy varies depending on the time of day, one-tariff or multi-tariff meters are used. The latter can be adjusted taking into account the day or night, weekdays or weekends, holidays, etc. As a rule, single-rate electricity meters have a longer shelf life due to the simplified design.

Requirements for the installation of the meter

In addition to matching the meter with the register of authorized devices, the device must be installed in accordance with the following standards:

• distance from the floor - no higher than 1.70 m;
• device must be rigidly attached to the shield and installed in a container or cabinet;
• the height from the floor to the contact area of ​​the device should be in the range from 0.80 m to 1.70 m;
• the wiring to the instrument must be of a continuous type( without twists and soldering);
• requires free access to the meter for reading, replacing and repairing.

The inspection of the condition of the seals and the reconciliation of the readings are authorized by the specialists of the Energy Supervision. The replacement of electricity meters in the apartment is determined according to the current regulatory framework.
