How much does it cost to check the electricity meter at home. Expiration of the calibration interval of the electric meter
The procedure for verifying electric energy meters in the laboratory of FBU "Rostest-Moscow"
For verification of electric energy meters in the laboratory of FBU "Rostest - Moscow", metering devices must be delivered to the address Nakhimovsky Prospekt, 31 to the Department of Metrological Support for Acceptance and Storage of Measuring Instruments, located at the entrance to the building of FBU "Rostest-Moscow" from Sevastopol avenue on the ground floor.
Acceptance of meters for verification is carried out from 8.30 – 17.30 (Mon – Thu) and from 8.30 – 15.00 (Fri)
If you are an individual, you must have a passport of a citizen of the Russian Federation with you.
If you are a legal entity, you must have a letter of guarantee with you.
The term for checking the electric meter takes no more than 15 working days from the date of payment for the work.
The cost of verification in the laboratory of FBU "Rostest-Moscow"
- Electric energy meters, single-phase active energy - 700.00 rubles. (price without VAT 20%);
- Multi-tariff single-phase and three-phase active and reactive energy meters - 1550 rubles. (price VAT 20%);
- Three-phase electric energy meters of active energy or reactive energy - 800.00 rubles. (price without VAT 20%);
- Three-phase active and reactive energy meters, bidirectional, multifunctional - 3400.00 rubles. (price without VAT 20%).
The procedure for verification of electricity meters for legal entities at the site of operation
For verification of electric energy meters on the road, it is necessary to send an e-mail or a letter of guarantee, indicating the exact address where the verification will be carried out, after which an invoice will be issued.
Departure of the verifier is carried out only after payment or signing of the contract, within the agreed time frame.
Please note that before the verification, the Customer is obliged to notify the energy supply organization about the removal of the seal from the meter.
There are regulations indicating for what period of time an electricity meter is designed.
After the expiration of the established period, the meter must be replaced, the energy company may send a resolution on mandatory replacement.
What is the life of the electric meter provided by the manufacturer, when it is necessary to change the induction, and when the electrical device.
And is it possible to continue to use the device if after the expiration date it still works properly.
The accuracy class of the meter means the maximum percentage of error (in any direction) that the meter can tolerate.
So, earlier devices of accuracy class 2.5 were allowed to work.
This meant that 2.5% of the energy could not be taken into account or, on the contrary, added.
For example, if the error is 2%, then a 100 W incandescent lamp can “wind” 98 W per hour, or 102 W.
Today, the requirements for the accuracy class are higher.
What is the service life of an electric meter
Electric meters are of two types, using different principles of measurement, and, accordingly, a different design.
induction or mechanical
The design is based on the principle of electromagnetic induction. The consumed current passes through the coil, which creates a magnetic field. This field rotates the disk, which is connected by a worm gear to the gears of the dial. The more current passes, the greater the magnetic field and the faster the disk rotates.
Single-phase induction counter SO-I446M
The service life of induction meters is considerable, about 30 years.
Electronic
Modern electronic metering devices are distinguished not only by high accuracy, but also by the absence of moving mechanisms, which theoretically increases their service life. “Theoretically”, since devices have recently entered our lives, and they have not yet been tested by time.
The instructions for electronic meters indicate the expiration date - 25 years - 30 years.
Electronic counter
hybrid
The concept of a "hybrid" counter, in fact, does not exist. The design of the device is either mechanical or electronic. Hybrid models are sometimes called models that have the external features of both.
The model can have a mechanical filling, but at the same time be compact, with an attractive interface, LCD display.
On the other hand, many electronic devices are equipped with a simpler and more familiar mechanical dial with scrolling numbers on the rollers.
Such a mixed version usually costs a little less and helps to save on the purchase of the device while maintaining the high accuracy of the electronic design.
Remote meters are used in private homes. ensures safe operation of the device.
You will find a scheme for installing an electric meter in a private house.
The transformation ratio of the electricity meter is a value indicating the accuracy of the device. How to calculate this value, you will learn.
How is the expiration date different from the calibration period and the warranty period?
At the time of checking and sealing any electric meter, its service life begins. This is not the same period of 25 years specified in the manufacturer's passport (25 years is an approximate period, the expiration date in which the device will remain in working condition, according to the factory's calculations).
In the documentation, next to the start-up date, the time and date of the next test to be carried out is put. Otherwise, this period is called the calibration interval (IPI).
The fact is that although the device as a whole continues to work, from time to time failures that are invisible to the eye may appear in it, an error may increase, which must be identified and eliminated.
The warranty period for electric meters, as well as for any other device, is the period in which the buyer can count on free warranty service, repair or replacement.
Various manufacturers indicate different dates warranty, for example, 5 years.
Calibration intervals may differ for different meter models. For single-phase - 2 years. For three-phase - a year. Electronic meters can be checked less frequently: once every 4 to 16 years.
Besides, different types inspections can be scheduled for different calibration periods. So, if an electric meter is subjected to metrological control once every 16 years, then it will be checked for serviceability of the internal battery and errors in operation every 6 years. Checking the reliability of connecting circuits can be assigned by energy sales organizations in accordance with their work schedules.
The essence of such a check (reliability of connection) is to remove the cover, remove dust from the contacts, tighten the bolts and seal again.
The start of the calibration interval is the date of sealing and commissioning, and not the date of production or purchase.
After the calibration interval has elapsed, the metrological service may conclude that the meter is still in good condition and can continue to be used.
What is meter verification, who does it and how?
The meter is checked for errors:
- Primarily at the manufacturing plant.
- Periodically. At the end of the calibration period, the readings of the electric meter are compared with control devices.
- Out of order. Even if the end of the verification period has not come, verification can be carried out in cases where the passport was lost, the seal was torn off, there were doubts about the correctness of the readings, instrument repair and other emergency situations.
Verification can be performed either by a representative of the power supply company or by a specialist from a certified metrological laboratory.
Finding the latter can be more difficult, but their services can cost less than a full-time electrician.
The verification procedure is carried out on site, dismantling of the equipment is not required. The operation of the electric meter is checked with an ohmmeter and a wattmeter in several operating modes.
In addition, the threshold of sensitivity is determined, an external examination of the hull is carried out, the strength of the insulation and the absence of self-propelled are checked.
If an error in the electric meter has been identified, the expiration date of which has not yet expired, the simplest and most correct solution would be to replace it with a new one. The hassle and cost of repairs are not worth the candle.
Conclusion
So, the service life of the device (approximate time of its proper operation) is indicated in the passport and is approximately 25 - 32 years.
The calibration period is indicated in the technical documentation by the checking electrician and starts from the moment the device is put into operation.
This is the time until the next check. Regular checks and comparisons of readings with multimeters are carried out every 1 - 2 years, more thorough checks are established by the energy sales company every 4, 6, 16 years and other periods.
The warranty period is the time during which you can get a warranty repair. It can be 2, 3 or 5 years old.
After installing the electricity meter, it is necessary to register it, for this a seal is placed. and who should put a seal, read the article.
How to take readings from a two-tariff meter correctly, see.
There is no need to rush service companies with checks, even if it is clear that the period between verifications has ended. But if a representative of the organization came before the expected time, you need to clarify the reason for the unscheduled verification and make sure from the passport that the time has really come.

To guarantee the correctness of the readings of the device, for example, a gas, electricity or water meter, a standardized procedure for comparing the data received from the device with a “standard” can. This procedure is called verification and allows you to confirm the accuracy of the meter measurements, as well as to allow or prohibit its further operation. In order to understand the essence of verification as clearly as possible, it is enough to recall the procedure for how the accuracy of a watch or any instrument that shows time is compared with a radio signal or television broadcast of the exact time.
As mentioned above, verification is not carried out for all measuring devices, but only for those that are officially recognized by the state and are related to the regulation of ensuring the uniformity of measurements. That is why meters of electric energy, water, gas fall under this classification. It is possible to carry out their official installation or dismantling only if the device, according to the results of verification, was entered in the State Register. Accordingly, it will not be possible to change the counter without verification.
Relevance of device verification
At the legislative level, verification for electricity meters became mandatory only in 2010, while other measuring devices have been undergoing this procedure since 2008.
The service is not provided free of charge, as it is not included in the list of mandatory utilities. There are two types of verification that can be carried out for measuring instruments:
- primary;
- periodic.
The process of initial verification is fully undertaken by the manufacturer. This is necessary so that the consumer can buy a meter that works according to the standards established in the state. Installation of an electric meter assumes that the user has a device that has passed the initial verification at the factory. Verification of water or electricity meters of a periodic type is carried out during the operation of the device after the expiration of the designated inter-verification periods. In some cases, it is possible to organize an extraordinary verification. The procedure may be prescribed if:
- the consumer has irrevocably lost the certificate of the previous verification;
- adjustment of water meters / electric meters was carried out;
- the old instrument was replaced with a new one.
Installation of water, light or gas meters does not require verification of the device; at this stage, verification carried out by the manufacturer is sufficient.
Verification terms
Each device for metering water supply or electric energy must have a document - a passport with the date of the initial factory verification. This is worth remembering, as many people make the mistake of calculating the time for periodic verification based on the date the device was purchased. The range of the calibration interval most often found in passports modern models counters, is 6-16 years.
The law establishes the terms during which the data taken from the electric meter can be considered reliable. For mechanical induction appliances equipped with a disc, this period is 8 years. Modern electronic meters have a long calibration period - up to 16 years. If the user decides to install a new model of the device, he will also need to invite a specialist to carry out verification.
Who does the verification
Verification has the right to be carried out exclusively by a representative of an accredited metrological institution. The price of the service may vary for a number of reasons. For example, the cost of checking electricity meters at Mosenergosbyt varies depending on the type of device - electronic or mechanical. In fact, the device must be provided by the owner. He must do this within the time limits described in the meter's passport or if inaccuracies are found in the readings. Inaccuracies in readings are also a reason for conducting periodic unscheduled verification.
According to the legislation in force in the Russian Federation, namely the Decrees of the Government of the Russian Federation No. 491, 442, 354, and the provisions of the Housing Code of the Russian Federation, the burden of maintaining the electric meter, including its verification (replacement), lies with the owner of the dwelling. And it is the owner who needs to monitor whether the meter verification period has expired, whether the meter complies with current legislation. More information about the installation and operation of electricity meters can be found in the article: "".
So, why is it necessary to replace a faulty electric meter? The fact is that in accordance with paragraph 59 of the Decree of the Government of the Russian Federation of 05/06/2011 No. 354 "On the provision of public services to owners and users of premises in apartment buildings and residential buildings", in case of failure or loss of an individual, common (apartment), room metering device previously put into operation, or the expiration of its service life, determined by the period of time before the next verification, the procedure for payments for consumed electricity may be changed. So, the first 3 months will be calculated according to the average monthly consumption, and then according to the standard of monthly consumption of electrical energy, established by the decree of the Government of the corresponding subject of the Russian Federation.
But serviceable meters consumers of electricity can change according to own will, for example, if it became necessary to install a multi-tariff meter instead of a single-tariff one.
Mandatory verification (replacement) is subject only to electric meters whose calibration interval has expired, or faulty metering devices. A meter is considered faulty if the disc does not rotate or rotates unevenly (jerks), the indicator or display does not work. The meter is faulty if there are mechanical through damage to the body, drilled holes, the viewing window is broken or peeled off from the body, or the tightness is broken.
The calibration interval is the period of time during which the meter is guaranteed to give correct readings. The calibration interval is indicated in the passport of the meter. The terms for checking meters are different, from 6 to 16 years, and depend on the model and type of meter. This information can be clarified with the power supply organization.
The consumer who has received the notification can choose between carrying out verification or replacing the electricity meter. Verification is carried out by the State Regional Center for Standardization, Metrology and Testing, this service is paid. As a rule, most of the metering devices that are to be replaced have an accuracy class of 2.5; such devices are not accepted for verification.
If the consumer decides to replace the electricity meter, you should contact the energy supply organization to conclude an agreement on the provision of services for the replacement or installation of the electricity meter with its sealing.
If this service will be provided by a third-party organization that meets the requirements established by the legislation of the Russian Federation, then the consumer, first, must apply in writing to the energy supply organization with the appropriate application to remove the seal and provide meter readings, wait for the device to be unsealed by representatives of the grid organization, and then install the meter and contact the organization that removed the seal to seal the newly installed meter. After replacing the metering device, contact the energy supply organization, having a general civil passport, documents for a new electric meter, an agreement with the organization that installed the device. If the new meter meets the requirements established by law, then after sealing, it will be allowed for operation.
The removal of the seal and the subsequent sealing of the meter in accordance with the Decree of the Government of the Russian Federation No. 442 dated May 4, 2012 are free of charge.
If the consumer decides to choose and purchase an electric meter on his own, then when buying an electricity meter, first of all, you should pay attention to the date of the initial verification carried out at the manufacturer (the device can be put into operation if the seals of the state verifier are not older than 24 months for single-phase electricity meters and 12 months for three-phase), accuracy class (not lower than 2.0).
The accuracy class of a measuring instrument is the maximum permissible measurement error, expressed as a percentage. Individual electric meters are manufactured with accuracy classes 0.5, 1.0 and 2.0; static watt-hour meters (electronic) - accuracy classes 0.2, 0.5, 1.0 and 2.0. The accuracy class of the device is indicated on its dial.
According to GOST 6570-96 "Induction active and reactive energy meters", the service life of single-phase electricity meters of accuracy class 2.5 is limited by the first calibration interval, and since October 1, 2000 they have not been verified, because these devices do not meet the requirements of the current standard. Simply put, electricity meters of accuracy class 2.5 with an expired calibration interval must be replaced.
Particular attention should be paid to the period of the calibration interval. This is especially important because, according to the law, the expiration of the calibration interval and the neglect of its verification make such a meter uncalculated, that is, despite its physical presence, calculations will be carried out for three months according to the average monthly volume of consumption, and then - according to the standards. And, of course, when choosing a multi-tariff meter, check that the meter complies with the tariff zones of the day established by order Federal Service according to tariffs: night zone from 23.00 to 07.00, peak from 09.00 to 11.00 and from 17.00 to 19.00 (the rest of the time not specified in the hourly intervals is a semi-peak zone, the day zone is considered the time of peak and semi-peak zones).
The next deadline for replacing the electricity meter is indicated in the contract with the energy supply organization, mainly for new types of electricity meters ("Granit-1", "Granit-2", SEO-1.15, "Puma 103", "Mercury 202.5", "Mercury 200.02" ) is 16 years old.
According to the law, electrical energy meters installed in residential premises must periodically undergo a verification procedure.
Verification of electricity meters is carried out by comparing the meter readings with the established standard.
Only trusted metering devices should be used, as stated in federal laws No. 102 (On Ensuring the Uniformity of Measurements) and No. 261 (On Energy Saving and Increasing Energy Efficiency).
Not everyone knows what verification of electricity meters is and confuse it with “check”. This is an official competent procedure for confirming their suitability for the possibility of further operation of devices as a metering device.
Law No. 102-FZ “On Ensuring the Uniformity of Measurements” regulates the mandatory verification of measuring instruments. Decree of the Government of the Russian Federation No. 250 dated April 20, 2010 lists 45 devices that are subject to verification. These include electricity meters.
Verification is primary and periodic:
- Primary. Carried out by the manufacturer after its assembly before commissioning.
- periodic. It is carried out during the operation of the device after a certain inter-verification period.
Extraordinary verification of electricity meters is possible if:
- the consumer has lost the verification certificate;
- adjustment or adjustment of the counter is carried out;
- The old device was replaced with a new one.
Each electricity meter must have a passport. The document contains the date of the initial verification.
The frequency of verification determines the countdown from the moment of the first confirmation of the accuracy of the electricity meter readings. The term for checking electric meters is established by law.
The established period for checking meters is the length of time during which the readings of electricity costs are correct.
The period of the calibration interval is indicated in the passport, usually varies between 6-16 years. After how many years it is necessary to carry out verification again, depends on the model of the device.
The readings of the electric meter are recognized as reliable:
- 8 years - it is necessary for a mechanical induction device with a disk;
- 16 years - for modern electronic meters.
The frequency of verification should not exceed the prescribed time.
Verification of metering devices is carried out by special metrological institutions that have accreditation for this type of activity (for example, the Metrology Standardization Center).
Responsibility for the verification procedure of the meter lies with its owner.. The meter must be delivered to the nearest standardization center and the delivery date must be agreed in advance.
According to Article 13 No. 102-FZ, measuring instruments must be submitted for verification in a timely manner.
If the owner has suspicions that there is no accuracy in the testimony, he has the right to initiate the verification procedure independently and ahead of schedule.
Who should carry out scheduled qualified verification of electric meters? Mosenergosbyt must notify the date of obligatory verification and send notifications to consumers.
Verification is a paid service, paid by the owner of the meter.
The consumer receives a notification, removes the counter, delivers to the CMS. After the procedure is completed, he submits a verification certificate to the territorial point of Energosbyt.
The institution confirms the admission to operation, the meter is started in calculation scheme. If the counter does not meet the required parameters, it must be replaced with a new one.
An electricity meter with an accuracy class of 2.5 may not be accepted for verification. According to GOST 6570-96 “Induction active and reactive energy meters”, metering devices of accuracy class 2.5 must be replaced, they are not re-calibrated.
The removal of the meter must be properly documented. During installation, electric meters are sealed by both the inspecting organization and the supplier company.
Self-breaking of the seal is prohibited, it can be regarded as an attempt to cheat and deliberately change the indicators. This is subject to an administrative fine.
The meters must be removed by qualified employees of the energy supply organization who are required to:
- record current readings;
- make an act of removing the device;
- transfer payment for electricity for the verification period, which is calculated on the average.
The meter is also installed by a representative of the electricity supplier company. In this case, the employee must:
- draws up an act of installation;
- seals the device, fixing the seal on the cover of the terminal block.
If the device has successfully passed verification, it must be sealed. The following fillings are made on the tool:
- a seal of the electricity supplier is installed on the cover of the terminal block;
- the seal of the company that carries out the verification is placed on the fastening of the casings.
The design of measuring instruments should ensure the possibility of applying the verification mark in a place that is accessible for viewing.
If, due to the design features or operating conditions of the tool, it is not possible to apply a verification mark on the tool itself, it is entered in the verification certificate or in the passport.
It is also possible to verify electricity meters without removing. The CSM specialist is called to the house. He makes verification by measuring the voltage in the network and including a known load in the network for a certain time.
The results obtained help to determine the error of indications, then an appropriate act is drawn up.
It is important to note that the owner of the electric meter has the right to independently choose the organization for verification.
It is not uncommon for electricity providers to aggressively impose their trustees, and cases of fraud are also widespread. If you receive calls demanding to immediately replace meters or carry out verification, you need to call Mosenergosbyt and check the information.
Many owners are interested in the question of how much it costs to check an electricity meter in 2019.
The regulation of the Decree of the Government of the Russian Federation No. 442 of 05/04/2012, item 145 regulates that all expenses for ensuring the operation of the metering device, its integrity, and safety fall on the shoulders of the owner.
The owner of the meter pays for verification. The cost varies depending on the chosen institution.
Checking the meter without removing it is a little more expensive, since the call of a specialist to the house and the urgency of the work are paid separately. But it often happens that verification without removal is more expedient and brings less hassle.
As an example, we can cite the cost of services for the verification of electricity meters of one of the companies.
The cost varies depending on the type of meters:
- single-phase active energy meters - 675 rubles;
- three-phase active energy or reactive energy - 765 rubles;
- single-phase and three-phase active and reactive energy multi-tariff - 1500 rubles;
- three-phase active and reactive energy, bidirectional, multifunctional - 3300 rubles.
The price is indicated without VAT 18%. Often, for the urgency of work on verification during the working day, you have to pay extra 100%, within three working days - 50%.
The electricity meter is the property of the owner of the living space in which it is installed. Regular verification should be carried out for all existing electricity consumption meters.
Documents evidencing the conduct of periodic verifications, as well as the passport of the device, must be kept.
If there is no relevant documentation, Management Company reserves the right to deem the instrument unusable and require re-verification or replacement.
