The increase in the cost of energy carriers dictates the search for savings. Sometimes the economic prospect of search literally lies on the surface, and, to be more precise, on the meter counter. Let's say that multi-tariff device is the right way to save money purse or plastic card. You will be helped by the helpful advice of those who have gone through a complicated and tedious journey "in the zone of special attention" to replace the device.

Electricity meter in apartment
In any apartment or house there are monitoring devices that monitor electricity consumption.
The expediency of resetting the meter should be based on the expected properties and capabilities of a certain type of electricity meters. Which electricity meter to choose for practical use?
Types of electricity meters
According to the principle of operation, the circuit and the assembly distinguish between induction and electronic devices. The main element of the induction counter is a counting mechanism that registers the number of revolutions of the moving element of the device. At present, inductive types of meters are morally obsolete.
An alternative is an electronic energy meter, in which the number of fixed revolutions corresponds to the output pulses.
Unfortunately, the total replacement of obsolete household equipment has not taken on grandiose proportions.
Therefore, before the electricity meter is preferred for replacement, it is necessary to study typical wiring diagrams.
Schemes for connection of meters
According to measured values, household meters are classified into:
- single-phase for measuring alternating current 220V, 50Hz
- energy meters three-phase 380V, 50 Hz.
Regardless of the connection scheme of the device, there are rules where to install the electricity meter and how.
single-phase circuits
Single-phase meter circuits are designed to account for the energy carrier at a single tariff.
Let's tell you, the single-phase electricity meter has the following characteristics:
- low power consumption
- standard telemetry output
- shunt current measuring device
- good protection against hacking and theft.
Naturally, the priority of a single-phase device in the possibility of using a one-, two-tariff and multi-tariff electricity meter in an apartment.
One-tariff direct counters, equipped with a mechanical indicator, have an accuracy class of 1.0.
Useful tips and details about single-phase meters are shown in this video.
Helpful Tips
It is known that in the vastness of our country, as well as in the entire civilized world, a differentiated two-rate electricity metering system has been adopted. This system and a two-tariff electricity meter allow you to pay for night hours (23.00-07.00) at a cheaper rate of almost 4 times.
So why not use this tariff system. By the way, full visualization of the tariff on these counters can be done with an optical button to view the LCD data or via the IR port of the RS-485 interface.
The question "How to switch to a more favorable tariff" is begging.
Replacing the electric meter
If you naively believe that replacing the meter in an apartment is easy to produce, then you are deeply mistaken in understanding how to connect the counter (legitimately). There is a long process of processing documents and coordination with interested authorities and individuals in the form of a comprehensive service for replacing the meter: "counter" + "parametrization" + "installation" + "sealing".
Certainly, it is possible to entrust the conduct of activities to specialists who monitor each replacement of a meter in the zone of increased attention. They have a right! But calculate the cost side of the replacement. In most cases, the real cost recovery for the purchase of the device, its own installation and connection takes place during the first years.
Installation and registration of a multi-tariff counter
To switch to a multi-tariff counter system, you will need:
- a statement on the desired replacement of the meter and the transition to a new tariff
- documents (technical conditions and the project agreed in RES)
- acquisition of a multi-tariff counter
- verification of the counter and the protocol of parameterization with the issuance of the document on the hands
- installation of a counter with a break and new sealing
- application for electricity at new tariffs
- conclusion of an agreement on permission to switch to a new tariff.
In practice, avoiding any point of red tape marathon, it does not work out. In the replacement and installation of the new device, several services are involved, exclude presence and dependence, which is impossible.
Are you interested in sealing the electricity meter, how to do it yourself? No way, do not wake up the broken seal in place.
Moreover, in the Instruction, the consumer of electricity is told: "... when replacing the old meter, you can not touch its upper seals (the seal of the electricity meter fixing the seal with the brand of the meter is factory or with metrology), but only the lower one on the clamping cover of the distribution terminal box (the seal of the responsible power supply organization) ".
The installation of a multi-tariff (multi-zone) meter will be justified for a user who actively uses electricity at night with a favorable low-cost tariff. Otherwise, to improve the maximum power consumption will help more sophisticated appliances equipped with programmable timers.
