Any apartment owner at least once faces this problem: who should change electricity meters and, in general, what to do if the meter breaks down? Let's try in this article to give answers to the most exciting questions.
Replacement of electric meters can occur for various reasons. In fact, the meter is a device designed to calculate the energy consumed. This means that he must pass the state metrological certification. If the life of your device has come to an end, make sure that its accuracy class is not 2.5. If this is the case, you will have to buy a new meter, since only devices that have a precision class of at least 2.0 are now allowed. But still you can find out who should change the electricity meter, even if you buy a new device. For example, "Mercury" is an electric meter, quite popular among city dwellers.
In addition to those instruments with an accuracy class of 2.5, replacements are subject to devices with expired verification period , counters with broken seal or technically faulty specimens.
It is necessary to find out how to connect an electricity meter, especially if it does not work correctly. Reasons for its replacement can be: lack of rotation of the disk or its uneven rotation, malfunction of the counter mechanism, violation of the integrity of the case, damage to the window on the front side of the device. At the same time, the costs of replacing the meter are entirely borne by the owner of the property.
And yet who should change electricity meters? Since its replacement is fraught with danger to life, this work must be performed by competent people with extensive experience in electrical equipment. When replacing, an act must be compiled, in which it is necessary to reflect the readings of the previous meter and the initial readings of the new device. Also, you need to make sure that the installation of the documentation is in accordance with all the requirements of the rules. Do not forget about the seal, without which the counter does not recognize any verification. You also need to keep the passport of the device, which indicates information about the initial state inspection at the factory.
So, we figured out who should change the electricity meters, and now it is worth knowing what exactly counters to buy. As already mentioned, the accuracy class should not be equal to 2.5. In addition, this device must be included in the state register of metrology. You need to buy a meter with a nominal current of up to 40 Amperes. Otherwise, it may even ignite the appliance. Earlier, it was allowed to use models designed for only 10 amperes, but now, with the appearance of complex technical devices, which have become much larger in each house, the electric network transmits a much larger amount of current, and the measuring device must comply with it. All old-style instruments should be immediately replaced with new ones to prevent an emergency. This will also help to better control electricity consumption, eliminate cases of energy theft, reduce the rate of charging for electricity and improve overall security in the entrance of the apartment building.
