How to take readings from a three-tariff electricity meter: step-by-step instructions for a multi-tariff device

How to take readings from a two-tariff device

Many consumers, especially older ones, are faced with questions about how to take readings from a two-tariff meter and the likely complexity discourages them from purchasing a profitable mechanism.
In fact, there is nothing difficult to remove. To make the purchase of a new device worthwhile, you need to use the device correctly and figure out how to take readings from a two-tariff meter. To avoid overpayments according to indications and the accrual of penalties, you must carefully monitor the transmitted indications, recording them monthly (preferably after the 25th day of the month) in a special notebook and paying regularly. A time period is selected on the display (indicated by T01, T02): the readings of electricity consumed during the day are taken into account at the tariff T01, at night - T02. You should press the “Enter” button. After this, at intervals of less than a minute (depending on the manufacturer, model), readings for individual tariffs are displayed

You should pay attention to tenths and hundredths of kW/h - they are separated by a dot, comma or other color. Integer numbers will correspond to the electricity consumed in kWh.

Procedure

To take readings from a multi-tariff meter, you need to:

1. First of all, determine the number of tariffs on the installed meter. There may be two or three. On the first days of the month, it is necessary to write off the readings recorded on the accounting device. On the three-tariff version, these data are indicated: T1, T2, T3. On the two-tariff electric meter, this information is indicated: T1 and T2, respectively. There is no need to write down the entire indicator; you can write down the numbers that come before the decimal point and the one after it. For example, if the display shows 564.233, then you need to enter 564.2.
2. To remove the indicators, you must press the “Enter” button. The display will alternately highlight the required combinations T1, T2, T3 or T1 and T2 with a two-tariff view. The button is pressed once, and the device will automatically display the data with a break of 30 seconds.
3. After this, it is necessary to determine payment tariffs for energy consumed. If a gas stove is installed in the house and the accounting is kept by a two-tariff device, then the T1 readings (daytime) are paid at a cost of 3.80 rubles, and the T2 data (nighttime) are calculated at 0.95 rubles. If the house has a gas stove and the accounting is kept by a three-tariff device, then the first two costs remain the same, and T3 data is calculated at 3.20 rubles.

If an electric stove is installed in the house, the tariffs change slightly. Indicators T1 with a two-tariff and three-tariff system are calculated as 2.66 rubles, T2 - 0.67 rubles. And half-peak hour (T3) is calculated at the rate of 2.24 rubles.

• Next, fill out the receipt. When multi-tariff accounting is maintained, different payment codes are used. With a three-tariff meter, these indicators are as follows: T1 - 13, T2 - 2, T3 - 15. When a two-tariff meter is installed, the following codes are used: T1 - 1. T2 - 2. From the last readings, you need to subtract the previous indicators of the device and multiply them by the corresponding tariff value.
• Next, the results for three or two obtained indicators are summarized. If the home owner has any benefits, their amount is deducted from the payment amount received. The receipt can be paid at any savings bank or post office.
• If you lose your last payment receipt, all the necessary numbers can be found on the meter. To do this, press the “Enter” button and hold it for 2 seconds. The device alternately displays all previous indicators at the time of the last payment. The multi-tariff meter retains all information about the indicators throughout the entire period of use. This greatly simplifies the comparison of the device readings with the figures of the latest payments.

The benefit in this situation is very noticeable. These devices are a real opportunity to save your own money.

Three-phase or single-phase design

When purchasing, it is important to clarify for which network this electric meter model is intended. The signs are as follows:

The signs are as follows:

1. A 1-phase device has two terminals on each side, that is, four in total.
2. 3-phase has at least four terminals on each side, that is, at least eight in total (there may be additional ones).

Those who live in city apartments need to purchase a 1-phase meter. But owners of private houses, if they do not know the number of phases, should first calculate the number of wires in the line connected to the house. If there are two of them, the network is 1-phase, if there are four, it is 3-phase.

A 3-phase model can be connected to a single-phase network without any problems, so those who currently have one phase, but plan to switch to a 3-phase power supply in the future, can safely purchase a three-phase meter. But, of course, it is impossible to connect a 1-phase meter to a 3-phase network.

The electric meter cannot be returned or replaced if it does not fit. The fact is that when selling a device, a special mark is placed in the passport - because of this, the product, as they say, cannot be returned, unless, of course, a manufacturing defect has been identified.

Therefore, when purchasing, all parameters and characteristics of the meter must be checked with all possible thoroughness.

In addition to phasing, pay attention to:

• rated current: must exceed the maximum of the input circuit breaker by one step;
• accuracy class.

An important characteristic is the noise level (some models buzz).

What do you need to know?

• When planning to take readings from a two-tariff meter, use a piece of paper and a pencil, because you are unlikely to retain a large series of numbers in memory, and the slightest mistake will lead to incorrect calculations.
• Check the electricity meter regularly for physical damage.

Important! If you find defects in the form of a broken seal, erased numbers or a faulty case, immediately contact your utility service. Refrain from taking readings until you consult a specialist.

• When installing the device, you must receive a passport with the specified date of verification of the mechanism. When installing the device, the RES employee must explain how to maintain a two-tariff electricity meter and how to take readings correctly.
• Don't try to fool the technology. Modern technologies will definitely reveal the deception, and the violator will be punished with a fine for an offense.

Important! Damage to the meter mechanism due to the fault of the apartment owner is subject to administrative punishment.

How profitable is it?

It is impossible to say unequivocally whether installing a two-tariff electric meter is beneficial or not. Tariffs in each region of Russia are set separately. In some, the difference between the night tariff and the single tariff can be 3-4 times. But, more often than not, night charges are approximately two times less (compared to day charges). And even under such conditions, you can save a fairly large amount - 1/3 of monthly charges or more. True, for this it is necessary to transfer the operation of electrical appliances to the night. Tariffs for some regions of Russia are shown in the table. It can be used to estimate the difference in tariffs.

Single-zone and two-zone electricity tariffs for 2016 for some regions of Russia

After analyzing the table, you realize that not everything is as rosy as it seemed. In some regions, where daily rates are much higher than single-tariff rates, savings are a big question. The night benefit is eaten up by overpayment during the day. In such areas, everything needs to be carefully calculated (see below for how). When making calculations, you need to take into account that you will buy a new two-tariff electricity meter with your own money, as well as reprogram it if necessary. So for a while you will simply be recouping your investment. And no one is immune from changes in tariffs or the legislative framework. And it may well happen that in a few years it turns out that you pay more on a two-tariff meter than on a single-tariff meter. There are already many such cases.

How you can save money

Modern household appliances may have a delayed start function. Thanks to it, you can do laundry at night, wash dishes in the dishwasher, prepare breakfast (multi-cookers, bread makers and other similar equipment). Some even heat water in storage boilers at night, closer to the morning, by setting timers on them. In addition, a fairly large number of “standard” equipment operate at night - a refrigerator, air conditioners or heating devices. So, it may well be that the consumption at night will be greater than during the day.

Most modern home appliances have a delayed start function.

If the tariffs in your region are “normal” and there are savings, it makes sense to install a two-tariff electricity meter in large families where consumption is high. This system is beneficial for night owls who go to bed long after midnight. Their main activity occurs at night, so the main consumption will be during the lowest rate. But you can accurately determine whether this innovation will give you any tangible benefit or not only after calculations.

Determining economic efficiency

First, you need to find out the dual-zone and single-zone tariffs in force in your region. Then, within a few days (preferably a week), conduct an experiment. Transfer all possible technical processes to the night, and track how much electricity you consume at night and how much at daytime. Readings will have to be recorded manually at 7 am and 11 pm. It is necessary to write down taking into account the decimal places - this way the calculations will be more accurate.

How long do ordinary household electrical appliances last?

You summarize the readings collected over the week - separately for daytime, separately for nighttime. Multiply by the corresponding tariffs. You receive the amount you pay when switching to a two-zone tariff. To have something to compare with, count the total amount of electricity consumed (add the night and day parts) and multiply by the single-zone tariff. Now you can calculate the difference and evaluate whether this idea is worth getting involved with.

Excerpts from the forum

What is multi-tariff mode and its purpose?

As you know, the load on the energy system is uneven. During the day, electricity consumption is several times higher than at night (to be precise, the peak occurs in the morning and evening). In order to motivate the population, multi-tariff systems have been introduced in many countries, including Russia, taking into account the characteristics of a particular city (settlement).

The most common is the two-tariff system (day-night), and its three-tariff modification (peak-half-peak-night) is also found. The transition to such metering schemes can significantly reduce electricity costs. As an example, we give the prices for various time zones for the city of St. Petersburg (for an apartment with a gas stove).

Example: tariff table for St. Petersburg.

As you can see, the difference in price between night and day rates is slightly less than twofold. Even if you only turn on the washing machine when the nightly tariff is in effect, you can save a lot.

To switch to a two or three tariff system, it is necessary to install an electronic electricity meter, the design of which allows for such a count. As for induction modifications, they do not have such functionality.

How to correctly take readings from the device

To figure out how to take readings from an electric meter, you need to know its type. The principle of data recording may differ.

How to read an induction type meter

For old-style products, the numbers are visible on the display. If the wheel moves quickly, the values ​​can change several times a day. The digital series varies within 6-7 units. The latter is often highlighted in color or the window in which it is located is larger than the others. It is not taken into account when fixing values. For a number of devices, any selection is not provided by the manufacturer, so the controller records a completely digital series.

Before reading the meter, the inspector checks the values ​​for the past month or quarter recorded in the journal. The supplier often sends out receipts, which already indicate the difference in indicators after the controller has recorded the current consumption. If the property owner has submitted an application to change the device, then GorSvet is obliged to draw up an act that will display the amount of electricity wasted during the entire operation of the device.

How to take readings from an electronic meter

Electronic devices also have a window, inside which numbers and values ​​periodically appear. They are updated with some frequency, which allows controllers to make calculations using a standard algorithm that is suitable for a single-tariff system.

The multi-tariff meter displays the difference depending on the time of day: at night the values ​​are lower. The data recording algorithm changes slightly (the number of actions increases).

Mercury 200: taking data

Data recording from the Mercury electric meter is carried out in several ways, depending on the model of the device installed inside or outside the building. Multi-tariff ones have markings on the screen. It is fixed by pressing a special button located near the screen.

When using a single-tariff meter, the data is recorded with one press of the “enter” key. The designation T1 appears on the panel. A day-night device requires pressing the corresponding button twice.

How to take Mercury 230 electricity meter readings

Reading data from the two-tariff Mercury is carried out according to a standard algorithm. To record the readings, press the “enter” button once: the text T1 and a series of numbers appear in the window (kWh during daylight hours, from 8:00 to 00:00). The indicators are recorded in the log book.

Then the “enter” key is pressed again so that the T2 mark and other indicators indicating the amount of current wasted per night (from 00:00 to 8:00) are displayed in the window. The value is entered in the appropriate column in the journal.

How to calculate electricity using a multi-tariff meter

The final calculation is carried out using indicators for the previous and current months. Calculation example:

• for the current month: T1 - 1500 kW, T2 - 150 kW;
• for the last month: T1 - 1300 kW, T2 - 100 kW.

Mathematical calculations:

• 1500-150=1350;
• 1300-100=1200;
• 1350-1200=150.

How to read data from the Energomer meter

The main difference between the model and all the others is the presence of a key on the panel, which is designated by the abbreviation PRSM. Multi-tariff products "Energomer" are considered more innovative devices, so the models are almost identical in characteristics. The main disadvantages include the high price.

From the Micron counter

Micron electricity meters have a single key on the panel that needs to be pressed when recording data. After pressing, 2 dots should appear on the screen, moving chaotically around the window. The latter indicates zones divided into tariffs. When the point crosses the border of a particular zone, the display will display numbers indicating the number of kW wasted in 25-30 days. The T1 R+ and T2 R+ markings appear on the screen.

From the Saiman counter

Products of this brand replaced outdated devices from the 80s and 90s. release regardless of the region, so many are satisfied with Saiman devices. They are convenient to use in everyday life: there are no buttons on the display to record data. Numbers indicating the consumed kW appear on the display once a day.

You can track a certain periodicity: first, the device identification code appears, the kW value itself, the date and the inscription “Total”. Single-tariff products are easier to use; data is displayed on them instantly. In two-phase devices, the sequence is shown by zone (T3, T2 and T1).

Payment methods

Users who have switched to a differentiated electricity metering system are faced with the question: how to calculate payments for a two-tariff electricity meter?

Costs for different tariffs are calculated separately.

Calculations for a two-phase meter occur in several stages:

1. Rewrite the daily readings.
2. By pressing the “Enter” button, record the night readings.
3. Calculate the difference in readings for each category.
4. Multiply each indicator by the cost according to the tariff.
5. Add up the resulting numbers.
6. Enter the total amount on the receipt.

As you can see, there is nothing complicated in the procedure for taking readings. It is produced according to the usual scheme.

Reference! To find out how to pay the day-night meter readings for your model, refer to the instructions that came with the device.

According to the electricity meter

The current data is subtracted from the device data for the previous month. The difference will indicate the actual electricity consumption in kilowatts. This scheme is always used, regardless of the type of meter. If in one month you submitted less than actual evidence, you will pay less, and in the next month more. One way or another, if you submit readings taken from the meter, the actual consumption will coincide with the accrued one.

Payment taking into account the social norm of consumption

In the receipt for utility bills for light, specify the social norm of consumption. Subtract the value of the social norm from the readings obtained. Multiply the remainder by the cost of a kilowatt at the regular tariff, and multiply the social norm indicator by the cost of a kilowatt within the norm. Add both sums. The resulting number is the amount to be paid.

Without electricity meter data

You can pay for electricity without a meter in the following cases:

1. The device is broken.
2. There is no counter.
3. There is no way to take readings.

If the meter breaks down, the date on which this happened is recorded. If it is not known, then the month in which the device failed. Three months are given to replace the meter, during which charges will be made based on the average for the last six months. After 3 months, payment will be calculated according to the standard.

Attention! If supervisory authorities suspect that the meter has been deliberately damaged, then payment will be calculated according to the standard increased by 10 times. Such calculation will be carried out from the date three months before the discovery of the breakdown and until it is eliminated.

There is no meter in the apartment. Most often, this situation occurs in former dormitories. In this case, payment for electricity is calculated according to the standard.

Three indicators are taken:

• number of registered;
• electricity consumption standard;
• electricity tariff.

The product of these indicators is the cost of electricity to be paid.

If you stop submitting meter readings, then charges will occur based on the average for three months, after which the standard will appear on the receipts. This is less profitable, so it is better to transmit the correct readings to the energy sales company on time.

How are readings taken?

We take readings from the electric meter. Photo No. 3

Readings from any electric meter are taken either by the owners of the facility in which the device is installed, or by authorized persons from the management company that provides utility services to a specific group of people. At the same time, the owner of the property has every right not to allow his meter readings to be taken either by representatives of the management company or by other persons.

In this case, the cost of electricity provision services will be calculated at average regional tariffs.

The actual procedure for taking readings is different for different types of three-phase meters:

• When using a device with an inductive counting form, in order to obtain the required numbers, it is necessary to copy the available readings on the rotating display of the device onto a piece of paper. If one or two digits, usually out of five or six in general, have a different color than the rest, then when readings are taken, these numbers are discarded (they show an intermediate calculation of electricity consumption on a small scale, so they are not taken into account when determining monthly readings).
• When using an electronic meter, you will have to refer to its instructions. The fact is that different models of meters show 10-15 seconds: time, date, power consumption indicators for all time and by periods (T1 - 7-23:00, T2 - 23-7:00, T3, T4, etc.). d. – grace periods). As a rule, the sequence of displaying values ​​corresponds to that described above, however, for the most accurate determination, you should refer to the previously mentioned counter instructions.

Taking readings from a three-phase meter is only half the battle. Next you will have to do the following:

1. Determine how much electricity was consumed over the last month. To do this, it is enough to take the meter readings for the previous month and subtract them from the currently available ones. You can find out these readings either by monthly recording, or by looking at the last paid receipt for electricity.
2. Multiply the resulting electricity figure by the current tariff in your region. So, for example, with an electricity consumption of 200 kW per month and a tariff of 4 rubles per 1 kW, you will have to pay 200 * 4 = 800 rubles.

As you can see, there are no particular difficulties in working with three-phase electric meters and taking readings from them is as easy as shelling pears. We hope the material presented above was useful to you. Good luck paying your utilities!

Energy meters

Taking readings from the Energy Meter day-night electricity meter (two-tariff or multi-tariff) occurs in exactly the same way. The difference is that the button on these electricity meters is called “PRSM” (view). There may be two or three buttons, depending on the modification.

Electricity meter Energomera CE301

When you click on this button, numbers appear showing how many kilowatts were “increased” for each tariff zone. There are no more differences.

Take readings from the Micron electricity meter

In Mikron multi-tariff electronic electricity meters, there is only one button on the case, and you need to press it to display the required readings on the screen. Only in this case, you need to wait until “checkmarks” appear on the display above the letters “T1” and “R+” (see photo). This will be the reading for the first tariff.

How to take readings from the Micron electric meter model SEB-1TM.02M

Then click on the same button until the checkmarks appear above T2 and R+, if there are more zones, click further. This is how readings are taken from this day/night meter.

Saiman counters

Now in many regions they replace old induction meters with electronic ones free of charge and most often install devices from Saivan. These are very simple devices; they do not have buttons that can be used to forcefully “scroll through” the readings. You just have to wait until the required value is displayed. That is, in this case, take readings from the electricity meter - just wait until the required value (TOTAL) is displayed and write it down on the receipt (or transfer it to the appropriate service).

To make it easier to navigate, here is the order in which the data is displayed in this electric meter:

• date of;
• time;
• meter number;
• gear ratio (1600);
• TOTAL - readings of a single-tariff meter or are displayed sequentially T1, T2, TOTAL for day/night type meters (two-tariff).

It is necessary to record the TOTAL or T1 and T2 readings and also the general TOTAL readings on the receipt. Let us remind you once again that you only need to write down the whole part, without taking into account the numbers after the decimal point. You can watch the same information in video format.

Video on the topic

The cost of electricity is rising from year to year. And today, as active users of electricity, such devices are installed in almost all apartments. Using an electric meter allows you to clearly keep track of consumed electricity and save your family budget. In turn, this makes charges for consumed electricity transparent. In addition to the single rate, there is a double and even triple rate. First of all, the consumer is frightened by the alleged difficulty in submitting data to energy supply companies, since there is no knowledge of where the time is and what T1, T2 and T3 mean in the meter.

In what cases is it necessary to install more than a single-rate counter? We’ll look into it further. To do this, you need to calculate as accurately as possible the active use of electrical appliances - at what hours, what equipment and for how long you need it in operating mode. Is it possible to move something to night time: many washing machines and dishwashers are equipped with a delayed start function, but only a few use it. Then it is necessary to clarify the difference in charges per kilowatt for day and night use in the region, which must be paid monthly. If the difference is noticeable, then we will find out the cost of the device and the cost of installation in order to calculate the payback time for such an acquisition. An impressive portion of users talk about 6-18 months. Naturally, few are willing to devote time to such research.

Therefore, you can go by reasoning. If you are at work all day long, and there is not a lot of smart technology in your apartment, and you sleep at night, the installation is pointless and will most likely lead to an increase in payments. If you are the happy owner of smart appliances, such as a dishwasher and washing machine, a boiler, an air conditioner and heated floors, and your TV and computer often work at night, you can get some savings. It’s just important to remember that a broken regime has never made anyone healthy. And the noise from the washing machine can cause discord with neighbors. The approach to choosing equipment should be individual.

Types of three-phase multi-tariff meters

According to the type of design, three-phase metering devices are divided into 2 groups:

• electronic - transmit the number of counted pulses to the controller;
• induction - read the number of revolutions from a disk that moves through a magnetic field.

According to the type of connection, the following three-phase multi-tariff meters are distinguished:

• straight;
• semi-indirect;
• indirect.

The direct connection device is connected to the cable distribution, the cross-section of which varies between 15-25 mm2.

The maximum current parameter of three-tariff devices is no more than 100 A, and the power is 60 kW.

Instructions for installing the meter are indicated in the instructions. Installing a three-phase device is quite complicated; the devices are designed for heavy loads, so it is recommended that an experienced electrician carry out the installation work.

Manufacturers and prices

Electricity meters of any type are single-phase and three-phase. Two- and multi-tariff too. There are no differences in this, as well as in appearance. The difference is usually in price, but this is understandable - more complex equipment has a higher cost.

The most in demand on the market are two-tariff electricity meters from the Moscow Electrical Instruments Plant (MZEP). It’s not so much about the quality (it’s average, by the way), but about the price - these are the most inexpensive metering devices of this type. The company produces two-tariff energy meters SOE-55. They are available in eight modifications. They differ in the maximum current they are designed for and the number of zones that can be programmed. Any model can have two types of housings: for installation on a Din-rail or in a special box. The price of two-phase electricity meters SOE-55 is from $20 to $30, and this is in the retail chain.

Two-tariff energy meters SOE-55 in two cases - on a DIN rail and in a box

Energomer meters are available with the marking 102 in 4 modifications, with the marking 208 - in two. Each of the modifications can be made in several housings - a standard one for mounting in a box and one with protrusions for a DIN rail. There is also a housing with a remote reading indicator.

According to reviews, the units are quite good; products of this brand are distinguished by powerful terminals for connection, which is always good. They also have a warranty period of 5 years from the date of issue. In terms of prices - simple models cost about $23, with a remote control - $130.

Two-tariff electricity meter Energomera CE 102

Quite popular products from Moscow are Mercury counters. There are three modifications of multiphase meters of this brand: Mercury 200, 203 2T, 206. They can count 4 different tariffs, it is possible to program up to 8 zones per day, set 8 types of days (sometimes weekends and holidays are also counted at a reduced tariff). It is possible to set up to 12 seasons. Cost from $25 to $70 (depending on the degree of sophistication).

A two-tariff electricity meter is connected in the same way as a single-tariff one. There is no point in dwelling on this, everything is described here .

Rules for taking readings from electronic electricity meters

Devices of this type are equipped with an electronic display containing information relevant to the user. Here you can find not only current energy consumption readings, but also information regarding the date and time of operation of the device. For most models, this data replaces each other on the display with a specified frequency. For multi-zone models, readings are displayed in the corresponding zone.

To take readings, just wait until the relevant information appears on the electronic electricity meter. You can also press the corresponding “enter” button several times until the display displays the relevant information, which should be written down on a specially prepared piece of paper.

By the way, modern meters have banks with information. One of them stores the total consumption since the device began operating, in the other you can view readings for the last 11 months.

Functionality

Models with advanced capabilities are equipped with a network interface. It provides a connection to a personal computer. Thanks to specialized software, you can keep track of electricity consumption and transmit readings.

The digital meter may contain memory cells that allow you to record readings by month. This function allows you to avoid conflict situations in the event of an erroneous invoice.

It is also possible to view current indicators:

• current consumption;
• tension;
• power (active or reactive).

How to send by phone

PJSC Mosenergosbyt and LLC MosOblEIRTS launched a robotic service for receiving and processing data from electricity consumers. You can submit your testimony by calling +7 (499) 550-9-550. The service is equipped with a modern IVR system.

How to submit readings:

1. Dial the service number indicated above.
2. Wait for the robot operator to say “What are you interested in?”
3. Reply “Indications”.
4. Follow the robot's instructions: speak out the numbers of your personal account and the counter data.
5. The system automatically recognizes the data.

Why does the meter consume a lot of energy?

And before considering the immediate causes of phenomena that can generate more electricity than necessary, it is worth analyzing the likely sources of distortion of real results. As a rule, these are:

1. Season. In winter, the use of light and heat-producing devices increases. This is not entirely obvious and a person does not always notice that he has begun to use more than usual.
2. Replacement of conventional devices. If the meter has a disk, then it may not respond to a small device, but if it is a digital version, then the count will be kept until the phone is charged.
3. Meter components. If the device itself is assembled from cheap materials, then the accounting will be exceeded several times only due to technical instability.
4. Wear. It can be either during prolonged use or under constant high load. Nothing but replacement can be done here.

There is no perfect device, and therefore absolutely everyone can have distortions

It is important to understand where the indicator deviates from the norm and where it shows a completely incorrect result.

Pros and cons of equipment

The advantages include the opportunity to save electricity, more than halving its cost at night. Therefore, if you are a “night bird” or are ready to adjust your electricity use schedule to the tariff, then there will be an obvious benefit for you.

Another plus is that the power grid is less congested at night; repair work is usually carried out during the day. Therefore, turning off the lights at night is unlikely.

Of the minuses, we emphasize that during the daytime the cost of electricity will increase. Moreover, the “day zone” is considered to be the period of time up to 23 pm. If you are used to actively using light at this time, for example, watching TV, sitting at the computer in the evening, running the dishwasher after dinner, cooking on an electric stove, then your consumption will increase.

Attention! Saving with a two-tariff meter will be easy for those who are used to actively using electricity between 11 pm and 7 am. If you use powerful appliances during the day, you won’t be able to save money.

The principle of operation of a two-tariff meter or how electricity consumption is calculated

A meter that counts according to two tariffs looks similar to a regular one. It has two display screens. One calculates daily consumption, and the other calculates nighttime consumption. The “day zone” is from 7 a.m. to 11 p.m., and the “night zone” is from 11 p.m. to 7 p.m.

The following tariffs apply in the Moscow region:

Let's calculate whether there will be any benefit from splitting tariffs. The tariff for a regular meter is 5.38 rubles/kWh and the tariff, differentiated day/night: the cost during the day is 6.18 rubles/kWh, at night – 2.29 rubles/kWh. So, if you use two-tariff metering, then during the day you pay 80 kopecks more for one kWh, and at night you save 3 rubles 9 kopecks for one kWh. To equalize consumption, it is necessary that for each kWh used at night, there should be no more than 3.86 kWh of the “day zone”. If the ratio is higher, then there will be no savings; on the contrary, it will be more expensive.

Why do we need different tariffs on a modern meter?

Unlike old meters, modern ones can take into account several tariffs. However, why is this necessary? As you know, electricity is consumed most actively during the day and evening. High loads on substations and other electrical network components have a negative impact, which, in turn, accelerates equipment wear.

To reduce the load, such additional tariffs were introduced. That is, you need to pay one rate for the day, and a different rate for the night. For example, during the day 1 kilowatt will cost, relatively speaking, 2 rubles, and at night it is already 50% cheaper. Thus, the owners of houses and apartments have the opportunity to save their own money, and for the supplying organization, to significantly reduce the load on the power grid.

Based on this, calculating the cost of electricity using a two-tariff meter is much more profitable than using an old-style electricity meter.

How to calculate electricity if there is no meter

If a meter is not installed in the house or its calibration interval has expired, then it is impossible to transmit the readings. In such situations, accruals are made according to the standards, that is, according to the indicator established in the region. Here it is worth considering that the energy supply company has the right to apply an increasing factor of 1.5 if residents have the technical ability to install a meter, but they do not do this for some reason.

The following indicators are taken into account:

1. Number of permanently and temporarily registered persons.
2. Living space area.
3. The current standard in the region.

All data is multiplied and, if necessary, increased by a factor of 1.5. The result is the amount to be paid.

Electricity consumption rates without a meter directly depend on the following points:

1. Number of rooms.
2. Number of residents, including those temporarily registered.
3. The region where the object is located.
4. Type of stove installed (gas or electric).

Methods for transmitting readings

There are several ways to transfer information about energy consumption data to the organization that is the supplier:

• Go to the company yourself . The information taken from the meter and entered into the required document is taken to the company. Here you have the opportunity to pay immediately for the services provided.
• You can transfer information remotely via computer . To do this, you need to log in to the service provider’s website. The readings are transmitted through your personal account or the corresponding fields on the website.
• Some multi-tariff meters are multifunctional devices , and therefore can themselves send data on energy consumption. If this service is activated, then there is no need to remove or calculate anything - the meter will independently perform all operations automatically.

Description

Electricity consumption is recorded using a meter at a certain tariff. However, in practice it is known that at certain times of the day energy consumption is more intense than at others. Therefore, organizations selling this resource enable consumers to switch to different tariffs depending on the time of day.

Tariff validity periods

The benefit of switching to three-tariff metering is that if the consumer distributes electricity consumption in such a way that the most energy-intensive actions are performed during the period with the minimum tariff, then he will be able to save on payments. It should be taken into account that night rates may differ from day rates by four times.

When using three-tariff metering, the highest cost of electricity will be at the time of day when its consumption is maximum. At half-peak consumption, the tariff will be less high, and during the night it will have a minimum value.

Types of counters

Accounting principle

The two-tariff plan involves dividing the day into “Day” and “Night” segments:

1. Daytime period 7:00 – 23:00 (in some places until 22:00).
2. Night period 23:00 – 7:00.

If you compare the cost of a kilowatt with a single-tariff plan, then at night it will cost significantly less, but you also need to take into account the fact that daytime kW costs more.

The difference between a single-rate tariff and a daily two-rate tariff is the first thing you need to pay attention to when deciding whether to switch to it or not.

In some regions the difference is a few kopecks and is practically not felt.

In others, 25 - 55 kopecks and may not be profitable for most consumers.

The transition to differentiated energy metering is beneficial for those who work a lot and are not at home during the day, and in cases where the apartment has powerful energy-intensive equipment, the inclusion of which can be scheduled at night.

These can be heaters and electric heating boilers, boilers, dishwashers and washing machines and other programmable appliances.

There are also plans that take into account peak energy consumption times. These are several morning hours when most businesses start working (7:00 – 10:00), and evening hours when people return home and turn on household appliances (17:00 – 21:00).

• The night tariff is the same as in the two-tariff option.
• The daily peak is the most expensive.
• Daytime half-peak costs the same as a single-rate plan.

The meters are produced programmed for modes. You can read about what exactly these plans are in the instructions. It will indicate how many modes there are and at what hours. And also, does the payment system change on weekends (in some plans, on Saturday and Sunday, the grace period starts at 15:00).

Also, a certain number of days per year (usually 16 - 21) can be arbitrarily set as “red” holidays, on which a reduced tariff will apply. It is important for such devices that the date and time are set correctly on them.

In any case, to truly save on energy in this way will require planning. There is a positive experience when a large-volume water boiler was installed in comfortable houses, which was heated at night at a minimum rate. During the day, this water was consumed, and the central hot water supply was not used, which made it possible to save money.

By calculating the monthly benefit and dividing the cost of the equipment by it, you can find out the payback period of the device.

Mercury counters: varieties

First you need to familiarize yourself with all the Mercury meters that have gained popularity in our country. Let us note the fact that the Incotex company, which is a manufacturer of these units, has been a leader in modern markets for quite some time and produces not only electric meters, but also many other electronic equipment.

So, among the best Mercury counters are:

• Mercury 200;
• Mercury 201;
• Mercury 221;
• Mercury 230;
• Mercury 231;
• Mercury 321.

Separately, you should pay attention to the 200 series. Such units are mainly used in single-phase networks, with alternating current in the main circuit

In nominal metering, voltage is coded in volts. In this situation, electricity metering is done according to a single tariff plan.

The 201 series meters are considered to be the most popular. They have become widespread and therefore are currently used as the main installation for monitoring electricity metering not only in private homes, but also in enterprises. Such meters are the most functional; they can be not only single-phase, but also two-phase. As for the design, it is of excellent quality and is protected from any type of hacking.

An electric meter from this manufacturer can be:

Each electric meter requires a separate approach, and it is very important to know how to correctly take readings from them. The meter must be installed by a person from a special service, who will put a seal after installation

The meter must be installed by a person from a special service, who will put a seal after installation

This category includes several more serious types of counters:

All of them are used depending on the area in which the measurement should take place. The listed types are designed to operate with a rated current of 5A, while the maximum operating mark is 60A.

How to choose the right electric meter

The market offers a fairly wide selection of manufacturers of modern models, which are definitely better than the old ones. To choose the right device, you need to pay attention to the following characteristics:

1. Type of power supply: single-phase or three-phase. In apartments and small garages, single-phase devices are installed, since a voltage of 220V is sufficient for these electrical networks. Owners of large cottage houses, industrial garages and enterprises will need to install a three-phase device with a voltage of 380V, since these are premises with increased consumption of electrical energy;
2. Number of tariff intervals;
3. Additional features such as surge protection.

Important! To the big advantages of modern models, it is worth adding the ability to record previous readings, which eliminates the need to carry out long footcloths with calculations. And some models automatically submit readings to the power supply organization, which generally frees the consumer from the need to write out and count anything.

But even if you choose a more modest device, today there are more than enough ways to transmit readings - this is the Internet, and the telephone, and a receipt in the mailbox.
