Two-tariff electricity meter: reviews. How to calculate electricity using a two-tariff meter?

Electricity bills are mandatory monthly payments. Therefore, it is necessary to replenish the personal account in a timely manner and prevent debts on it, so as not to be left without electricity. Today, utility bills are charged by the supplier, and customers only need to deposit money into the account on time.

But to control charges, experts advise making an independent calculation of the cost of electricity. And also such a practice will allow the consumer to find out how to save money when using electricity. In the review, we will tell you in detail about all the nuances of calculating the amount for light for individuals.

How to calculate the amount for electricity by the meter (including the cost of 1 kW of electricity)

To calculate the consumed energy resource, residents need to submit their readings to the management or energy sales company every month from the 10th to the 26th. It is also recommended to periodically independently calculate the amount to be paid in order to check the correctness of charges and identify for yourself where you can save in the world.

The procedure is simple, and every consumer can master it. The main thing is to follow the sequence of stages and know the established tariffs. The rates can be found on the website of your power supply company. They are usually installed at the end of the year and are valid for the next 12 months.

Take readings

Currently, there are two types of electricity meters:

induction;
electronic.

The former include older models. They are also called mechanical. Induction meters operate in the same tariff zone. The indicator is removed to the comma, that is, to the value highlighted in a different color. This is usually 5 or 4 digits.

Electronic devices are more accurate than mechanical ones and can take into account the energy consumed over several daily periods, therefore they are divided into the following types:

single rate;
two-tariff;
three-rate.

If you have the first option installed, then you need to take the indicator in the same way as for an induction meter. But two- and three-rate devices take into account the consumed energy over several time intervals, denoting:

“Day” or “Peak” - T1;
"Night" - T2;
“Half-End” - T3.

On such metering devices, the indicators are displayed alternately with an interval of about 30 seconds. The value of the daily rate can be indicated next to the digital display or in the lower or upper left corner. It all depends on the brand of the electric meter.

Reference! All indicators are recorded to the decimal value, that is, to the comma. Rounding up is allowed.

Enter and calculate by formula

After you have written down all the daily indicators, you need to calculate the energy consumed for the month. To do this, first subtract the previous readings from the data for the current month. If the electricity meter is multi-tariff, then calculate each rate separately according to the principle: from T1 current. subtract the previous T1, and so on.

The amounts received must be multiplied by the current tariff. For example, for 2020, Mosenergosbyt has the following rates:

Tariffs	Moscow	Urban population using electric stoves	Horticultural, horticultural, dacha BUT citizens	Other consumers
from January 1, 2020 to June 30, 2019
T1 (peak)	6.57	5.25	5.47	6.57
T2 (night)	1.95	1.37	1.95	1.95
T3 (half-peak)	5.47	4.37	4.54	5.47
from 1 July 2020 to 31 December 2019
T1 (peak)	6.57	5.58	4.97	6.57
T2 (night)	2.13	1.5	2.13	2.13
T3 (half-peak)	5.47	5.58	4.97	6.57

In order to get the total amount to be paid, you need to add up all three received amounts for daily rates. If there is a benefit, then it is deducted from the total amount.

If you have any difficulties in calculating electricity by the meter, then you can use the online calculator.

How to count electricity by the meter and the amount of payment for it?

In order to calculate the electricity consumption accounted for by the electricity meter, you will need to take readings from it twice. To do this, at the end of the next month (or during installation, if the meter is new), write down all the digits displayed on the scoreboard, up to the decimal point (in some models of counters, the digits after the decimal point are highlighted in a different color). The figures after the decimal point can be ignored, as they mean too little volume.

Exactly in a month (it is better to do this on a day to day), take the meter readings again and subtract the previous readings from the received figure - this will be the amount of electricity you consumed over the past month. To find out the amount that must be paid for the consumed energy, the resulting figure must be multiplied by the cost of 1 kWh. Data on the cost of 1 kW / h can be obtained from the receipt you received or by contacting the dispatch service of its supplier. Also, information about tariffs, as a rule, is posted on the official website of the latter.

The situation is approximately the same with two-tariff meters, which are now gaining popularity and are distinguished by the division of accounting for consumed electricity into night and day. In such metering devices there are two displays: one indicates the indication of the consumed electricity in the daytime, and in the other - at night. In order to calculate the amount, you will need to take both readings, subtract the corresponding readings obtained last month, multiply each of the values by the price of 1 kWh (it is different during the day and night) and add the resulting values.

How to calculate electricity if there is no meter

If a metering device is not installed in the house or the calibration interval has expired, then the readings cannot be transmitted. In such situations, accruals are made according to the standards, that is, according to the indicator established in the region. It should be borne in mind here that the power supply company has the right to apply a multiplying factor of 1.5 if the residents have the technical ability to install a metering device, but they do not do this for some reason.

The following indicators are taken into account:

The number of permanently and temporarily registered persons.
Living space.
The current standard in the region.

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

Electricity consumption rates without metering device directly depend on the following points:

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

Reference! Currently, a program has been introduced aimed at the interest of consumers in the installation of electricity meters. Therefore, tariffs are expected to increase up to 20% for those facilities where there are no metering devices, while the increase in electricity rates using meters is from 5 to 10%.

How to pay ONE if the house does not have a common metering device

If the house does not have a general house meter or its calibration interval has come to an end and the readings are considered invalid, then the electricity consumption is calculated based on the established regional standard. Also, the power supply organization, at its discretion, can add a multiplying factor of 1.5 to it. This applies to situations when it is technically possible to install a common metering device in the house, but the tenants (or the management company) do not seek to do this.

The utility bill includes the following:

The number of people registered on a permanent or temporary basis;
Apartment area;
The current standard for electricity consumption in the region.

How to calculate electricity by the area of the room

If a metering device is not installed in the house, then the consumer pays for electricity according to the standard established in the region. This rate is multiplied by the number of residents and depends on what type of stove is installed in the house and how many rooms. Square area calculations are not performed.

The current standards for one person in 2020 in some regions of the country:

Region	Object with gas stove (kW)	Object with electric stove (kW)
Moscow	50	80
St. Petersburg	78	111
Permian	185	263
Transbaikal region	65	96
Rostov region	96	156

Power consumption calculation

The task: how to calculate electricity consumption seems simple - add up the power consumption from the passports of all household appliances and multiply by the number of hours of operation. But for the calculation, it is also necessary to take into account the starting load, which for induction-type consumers is the same as during operation, and for capacitor-type equipment - much more.

Induction appliances include those that give off heat during operation - incandescent lamps, irons, stoves. For condenser - refrigerator, TV, washing machine, their starting power will be 2.5 - 3 times higher than indicated in the passport. For example, let's take 6 consumers:

electric stove - 500 W;
lamps - 15 W, 10 pieces;
iron - 2300 W, heating for 10 minutes per hour;
refrigerator - 170 W;
TV set - 200 W;
washing machine - 1000 W.

Power consumption in this case ((500 + 15 * 10 + 2300/6) + 2.5 * (170 + 200 + 1000)) / 1000 = 4.46 kW.

This number needs to be increased by 10% in order to create a safety stock. Thus, the required power is 4.9 kW.

Calculate electricity meter readings online

At present, it is not difficult to calculate the readings of an electricity meter online, since there are many sites with calculators on the Internet. For the calculation, you only need to enter the following data:

consumer group;
the number of citizens living;
accounting type;
the rate in force in the region;
enter readings from the device.

The calculator will independently calculate the amount to be paid. But many calculators do not take benefits into account. Therefore, if it is available, calculations must be made from the resulting amount.

How to take readings from three-phase meters

There are two types of three-phase electricity meters - the old type, requiring transformers and electronic direct connection (without transformers). If an electronic one is installed, it is necessary to take the readings of the electricity meter in the same way as described above. Just write down the values, wait until the required information is displayed on the screen, or "scroll" the data to the required page.

Connecting an electric meter in a three-phase network through current transformers

If a large power is allocated or there is an old-style metering device, a transformer is installed on each of the phases. To take readings in this case, you need to know the transformation ratio. The readings taken must be multiplied by this factor. The resulting figure will be the actual consumption.

But in general, you need to read the contract. The calculation procedure should be spelled out there - in some organizations they write out readings, below they put down the transformer data or the transformation ratio, and the actual calculations are made by the operator himself. So if you have a 3-phase meter, check the form and procedure for calculations when installing and sealing the metering device and putting it into operation.

Calculator for calculating a two-tariff electricity meter

If you have a two-rate device installed, then you need to calculate two daily zones: day and night.Night-time rates are cheaper, so you need to take these nuances into account when calculating.

To find out how much the monthly payment for the consumed resource will be, an online electricity calculator operating in the Moscow region will help. To get the value, it is enough to enter the following data:

location of the object (city, suburb);
readings from metering devices.

Calculations are carried out in automatic mode after clicking on the "Calculate" button.

If you have already tried to calculate the amount to be paid by yourself or have used an online calculator, then we ask you to share your experience. Your opinion is very important for other consumers, since on its basis they can draw conclusions and find the most acceptable option for calculating electricity.

Types of electricity meters

There are a huge number of different electricity meters. However, they can all be divided into three main types:

induction or mechanical;
electronic;
hybrid.

Mechanical devices

Structurally, induction meters are made as follows - between two coils, current and voltage, there is an aluminum disk, which is mechanically connected to the scale.

The principle of operation is that the current flowing through the coils creates an electromagnetic field that makes the disc rotate. It transmits its rotation to the counting mechanism through a worm gear. The more current flows through the coils, the greater the inductance of the electromagnetic field, which makes the disk rotate faster, and therefore the scale.

In the classification of meters, inductive are the most inaccurate. This is due to errors arising from the transformation of the electromagnetic field into the rotation of the disk. And also quite serious errors can occur in the mechanism of rotation of the scale.

The main advantage of this type is its low price.

With electronic mechanism

Electronic electricity meters have appeared relatively recently. They are based on measuring current by means of analog sensors. The information from the sensors goes to the microcontroller, where it is converted and displayed on the LCD.

The advantages of electronic include:

Small size.
The ability to customize several algorithms for calculating electricity.
The highest accuracy class among other types due to the lack of a large number of elements during measurement.
The ability to customize the ASKUE system.

The main disadvantages are the high price and high sensitivity to voltage spikes in the network.

Mixed models

Hybrid meters, as the name suggests, are a combination of inductive and electronic meter components. The measuring part from them is taken from the mechanical ones, and the processing and output of readings is carried out using a microcontroller.

This type was created in order to reduce the price of equipment that could be connected to the AMR system. This type is insensitive to voltage surges.

The disadvantages include large sizes and low accuracy compared to electronic ones.

How to take meter readings correctly?

Induction devices are "old" bulky devices with a rotating wheel.
Static - or modern electrical.

Many still have induction, but the tendency to switch to electronic models is already clearly visible - they count more accurately, and look better, and do not make noise.

When taking readings from an induction device, pay attention to the first 5 digits (for some models 4).

The last digit is usually put a little separately or highlighted in a different color, it rotates relatively quickly - as a rule, they do not write it in the receipt (for an even and simpler account) - these are indications after the "decimal point" in decimal fraction.

Otherwise, the organization makes calculations based on the average consumption over the past months - this data will be reflected in the receipt.

How to take readings from an electronic meter, multi-tariff readings

An electronic device can calculate a single tariff, or it can be configured for accounting for several tariffs (different tariffs are introduced in order to save money - during the day it is a little more expensive than usual, and at night it is much cheaper).

The desired mode is selected in the device menu (modes are usually changed by repeatedly pressing the enter button):

T1 - for single tariff.
T2 - for separate payment of the grace period from 23:00 to 7:00 in the morning.
T3 - one standard tariff and two preferential tariffs.

When alternately displaying these modes (T1 and T2), the device will show different readings that have "run over" for a month at this rate.

The difference with the previous readings is calculated for each tariff separately.

How to take readings from an electric meter when replacing it

Meters are changed due to their obsolescence, in case of suspicion of inaccurate readings and for periodic checking in the laboratory. What to do with the readings if the old meter was dismantled and a new one was installed?

Before the old meter is removed, the readings from it are copied onto paper.
