Mercury counters: varieties

For example, if you need to know the amount of energy consumed at tariff T1 for February, you need to subtract T1 January from T1 February. The difference is the cost of a certain tariff.

How to take readings from it is quite clear if you take a little time and carefully read what is written on the display. If you have another meter installed, you can also learn about the rules for recording readings from the article How to take readings from an electric meter. Many people are starting to use Mercury-230 electricity meters.

Old-style electricity meters are induction devices. They are characterized by a mechanical disk that spins on the front model of the device.

How to take readings from the Mercury 230 electricity meter

Taking readings from a single-tariff Mercury meter is not so difficult. To do this, pay attention to the 6-digit dial and write down all the signs up to the decimal point. In order to find out what indicator you received for the current period, subtract from the current data those that were taken last time.

As for taking readings from a multi-tariff meter, first you need to write down some readings.

Taking readings from multi-tariff Mercury occurs as follows:

1. Make sure the meter is in ready mode. In order to check this, you need to look in the upper left corner and find the line there at the “A” mark. If it is not there, then you will need to switch the counter to the required mode.
2. Switching to ready mode is done by pressing the button on the right. Most often it is located next to the “enter” button.
3. After the mode is activated, we select indicators. The change is made using the "Enter" button.
4. The first indicator that appears on the display is the energy consumption during the daytime; by pressing the key again, we will get the indicator for the night.

That's all, now you can issue a payment receipt and pay for electricity.

The electrical power of the meter is converted into an analog signal, which once again goes through the conversion process, but this time into a pulse signal. The main element of the electric meter is a microcontroller, which analyzes all signals and calculates the amount of energy consumed.

Also, with the help of this device, information is transmitted to output devices. As for induction meters, they consist of the following elements: an aluminum disk, a voltage coil, a calculation mechanism and a permanent magnet.

Induction

These devices are familiar to many of its users thanks to their glass window, behind which a special disk spins. The speed of its turnover depends on the amount of energy consumed. This type of electric meter is no longer relevant, as it is being forced out of the market by various modern analogues.

Due to its unprofitability, no one installs it now. Induction devices have more disadvantages than advantages, because their design does not allow automation of accounting and, under the influence of certain factors, can distort their readings.

Along with the use, the production of induction meters has also decreased. The reason for this is the preference for newer and more modern types of electricity meters.

Digital

These are newer devices that have become very popular today.

Compared to the previous type, digital electricity meters have many advantages:

All about electricians: power supply, electrical equipment, electrical installation

The uninterrupted operation of the electrical appliance allows you to record consumption both during the day and at night. By comparing the readings of the previous payment on the meter with the new data and carrying out simple calculations, the consumer pays for electricity.

Let's find out how to take readings from a multi-tariff meter (article Mercury 230 ART-01). To do this, you need to record the following data: T1 – current consumption during the day, T2 – current consumption at night. Before recording data, you must make sure that the device is in ready mode.

Can you tell me in Linux, when connecting Mercury 221, the device /dev/ttyUSB0 appears, is this enough or is a special driver still needed?

When the meter is connected to three-phase consumers, the process is carried out through current transformers. This scheme makes it possible to reduce the cost of electricity and increase the reliability of its supply. Direct connection meters do not make more than 100 A. This is due to the limitation of conductor sizes. The higher the current, the larger the cross-section of the wire required to pass it.

Functionality

• determination, recording and display on the liquid crystal display of information on electricity, including active and reactive in the total, separately for each of the 36 past months or 120 days;
• division into four prices and 16 zones with the possibility of individual settings for any month;
• determination of energy losses in the network;
• output of data on auxiliary current, power characteristics, voltage;
• archiving information separately for each type of electricity;
• recording peak loads in the morning and evening hours;
• recording the most important events in the journal;
• control and management of quality indicators.

The device provides the ability to record basic parameters in a log and then display them on external media.

Choosing an electric meter

Currently, Incotex has stopped producing devices operating on the induction principle, so only electronic modules are available for purchase.

It makes sense to purchase multi-tariff devices only if such a payment scheme is used in the region of residence and it is possible to use household appliances at night.

There is no point in purchasing a model capable of transmitting readings to the electric company if the latter does not have this capability.

It is debatable how necessary it is to purchase a device, for example, the 201 series, where after installing special software, it becomes possible to call the office to obtain detailed information. Additional modules that make up such an electric meter lead to a significant increase in the cost of the device. Again, as practice shows, the simpler the device, the longer it will last.

Now let's move on from general advice to specifics:

• Each Mercury electricity meter must be equipped with a passport and technical documentation, which indicates the capacity of the electricity meter, a description of how it works, a connection diagram and other useful information. The technical documentation should include an operating manual that describes in detail how to correctly take readings, information about the verification interval, etc.

In the absence of a passport, the device will not be able to be registered and, accordingly, operation will be impossible.

• There must be a hologram on the electric meter, as well as a factory seal.
• Compare the signs and numbers on the electric meter with the serial number indicated in the passport.
• Check that the warranty card is filled out correctly, otherwise the warranty for the electric meter may be invalidated. If such a device fails or does not work correctly (for example, it overestimates the significance of the readings, beeps, consumes a lot of energy from an additional source, etc.), then problems may arise with its replacement or repair.

Please note that inflated readings (the device has more kW than it actually consumes) are not uncommon. This indicates that the device is not adjusted correctly.

Mercury 230 - electric meter review, characteristics

Meters of this model are currently being produced. The price for Mercury 230 starts from 2300 rubles.

Some meters have only a whole part of kilowatt-hours on the drum of the counting mechanism, while others, in addition to the whole part, have a fraction of kilowatt-hours, which do not need to be taken into account when taking readings.

Especially for you, I have compiled tables for the most common single-phase and three-phase Energomer meters (data taken from the operating manuals), where the exact position of the decimal point is indicated.

Purpose

Three-phase static electric energy meters “Mercury 230AM”, “Mercury 230AM” (hereinafter referred to as meters), are designed for measuring and accounting for active electrical energy of alternating current in three and four-wire alternating current networks with a frequency of 50 Hz.

The operating principle of the meters is based on the conversion of input signals of AC power and voltage from analogue to digital form, followed by calculation of the amount of active electricity and its display on an electromechanical reading device.

The meters provide registration and storage of electricity consumption values ​​at one tariff from the moment of commissioning.

The meters can be operated either autonomously or as part of an automated data collection system.

The meters are intended for indoor use, and can also be used in places that have additional protection from environmental influences (installed indoors, in a cabinet, in a panel).

The meters have a built-in electromechanical reading device (hereinafter referred to as the CU) to display the measured electricity.

The meters are produced with different brands: “Mercury” - for sales with a Russian-language trademark and “Mercury” - for sales with an English-language trademark. Metrological and technical characteristics apply to both brands.

The meters are available in the following modifications: “Mercury 230AM-00”, “Mercury 230AM-01”, “Mercury 230AM-02” , “Mercury 230AM-03” (“Mercury 230AM-03”), differing in base (nominal) and maximum current, rated voltage, accuracy class and meter constant. Distinctive features of meters of various modifications are given in Table 1.

Basic and additional functions

Let's look at how to take readings from an electricity meter. The device has a 6-digit dial. You need to write down all the numbers up to the decimal point. To calculate energy consumption for a month, you need to subtract from the new readings those that were last month.

Popular types of single-tariff electricity meters: Mercury 230 AR/AM1 Mercury 230 AR/AM02 Mercury 230 AR/AM03
In order to record the readings of a single-tariff Mercury meter, look at the 6-digit dial and write down the numbers to the decimal point.

To determine the meter readings for the last month, subtract the readings that were a month ago from the current latest meter readings.

Meter with built-in computer

Electronic meters are produced without a rotating wheel, with installed digital displays. Due to their versatility, they have a standard menu where additional settings are located.

The latest models of electricity meters are much better equipped. Several phases can be summed up to them. This is very convenient considering that many consumers switch to two or three tariff plans:

All additional settings allow you to find out in more detail information about consumption at a certain time of day, the operating time of the meter and data on the readings T1 and T2.

The consumer's first impression is that it will be difficult to read information from an electronic meter. To do this, you need to study the manual for the electrical appliance or consult an electrician.

In addition, there are models that do not need to regularly take readings. They are connected to a common central network and send readings to a server at the power company. And you just receive a monthly electricity bill.

The gradual introduction of two-tariff energy metering allows saving on electricity, especially in apartment buildings, as well as optimally distributing energy. But here it’s also worth considering at what hours your consumption is greater and at which times it is less. If daytime consumption is small, and the main load occurs at night, then the Mercury 230 model is perfect.

Mercury 230. Operating procedure. Reading information from the meter indicator using buttons

The values ​​of metered energy by tariff zones can be read both from the meter indicator using the buttons on the front panel, and through the CAN interface (or RS-485 or IrDA or GSM modem). At the top of the LCD there are elements that indicate the type of energy: A+, A-, R+, R-, day, month, year, previous year and losses (Note - inscriptions can be in both Russian and English).

Reading information from the Mercury 230 meter indicator using buttons

When the counter is turned on, within 1.5 s, all indication elements are turned on: cursors, icons and all segments of digital indicators. After which the counter goes into the display mode of current measurements. The LCD of the counter during its operation when using the keys can be in one of three modes:

• in the display mode of consumed electricity;
• in the mode of recording the indication of maximum power;
• in the display mode of the current values ​​of auxiliary parameters (instantaneous values ​​of active, reactive and apparent power, both in each phase and the sum, current in each phase, voltage in each phase, cos ϕ in each phase and in sum, network frequency, and for meters with an internal tariff (additionally - current time and date).

Display mode of accumulated energy according to current tariffs.

When the meter is turned on, the liquid crystal display (hereinafter referred to as LCD) shows the amount of active energy consumed at the current tariff for the entire period of operation of the meter. This value is displayed in kWh, with a resolution of 0.01 kWh (two decimal places). To the right of this number are the units in which the displayed value is expressed (kW⋅h). The number of the current tariff is shown on the left (T1 is the first tariff, T2 is the second, T3 is the third, T4 is the fourth). At the top of the LCD there are elements that indicate the type of energy: A+, A-, R+, R-.

The counter has two indication modes: manual and automatic.

In automatic mode, the LCD screen sequentially displays information about the accumulated active and reactive energy for each tariff and the sum for all tariffs for each type of energy. The number of parameters is no more than 12 and no less than one and is programmed using the “Configurator...” program. The duration of parameter display is also set by the “Configurator...” program. In manual mode, when you press the “ENTER” key, the information on the LCD changes cyclically as follows: the sum of the accumulated active energy at all current tariffs, then the next time you press the “ENTER” key, the amount of accumulated active energy at tariff 1 is indicated, indicating the tariff number, with further By pressing the “ENTER” key, the amount of accumulated active energy according to tariffs 2, 3, 4 is sequentially displayed, indicating the tariff number. After the last tariff (if the meter is four-tariff, then after the fourth, if three-tariff - after the third, if two-tariff - after the second), the amount of accumulated reactive energy at all current tariffs is displayed, the subsequent pressing of the “ENTER” key displays the amount of accumulated reactive energy at tariff 1 with an indication tariff numbers. When you further press the “ENTER” key, the amount of accumulated reactive energy according to tariffs 2, 3, 4 is sequentially displayed, indicating the tariff number. In this case, the number of the displayed tariff is displayed on the left, and if the amount is displayed, then the inscription “Amount” appears in the lower part. The amount of information displayed on the LCD is determined by the configurator, but does not exceed more than 12 parameters and at least one. For electricity meters with software version 2.2.83 and higher (production began on 04/07/2008), information on all tariffs and on all types of energy (active, reactive) is displayed manually on the LCD. The ability to change this indication mode using the “Configurator …” program is blocked at the electric meter level.

Indication of auxiliary parameters.

When you briefly press the “” key, auxiliary parameters are displayed on the LCD screen in the following sequence: active power (W) – reactive power (VAr) – apparent power (VA) – network voltage (V) – angle between phases – load current (A) – cos ϕ – network frequency (Hz), and for meters with an internal rater – current time (s) – current date. The parameter is selected by pressing the “” key for a long time (more than 3 seconds). When you briefly press the “” key, the total parameter value and for each phase separately are displayed on the LCD screen. When indicating network voltage and current, the total value is not indicated. If during the timeout for returning to automatic mode (5÷255 s) the “” button is not pressed, the indicator goes into automatic indication mode.

Power peak indication

When you press the “ENTER” button for a long time (more than 2 seconds), the LCD screen displays the current month in the “month _ year” format. Next, short presses of the “ENTER” button lead to sequential display of morning and evening power maximums for the current month on the LCD. You can also look at the previous three months. When displaying morning maximum power, symbols T1 and T2 are displayed, evening maximums – T3 and T4. The type of power is indicated at the top with the symbol “-” in the appropriate place.

Manual clock correction mode.

Clock correction is carried out in the current time display mode. By long pressing (more than 3 seconds) and releasing the “ENTER” button, the current time is corrected. In this case, if the value of the seconds of the current time is less than 30 seconds, the moment the “ENTER” button is released, the seconds of the current time are reset to zero; if the value of the seconds of the current time is more than 29 seconds, at the moment the “ENTER” button is released, the value of the seconds of the current time is set to 59 seconds. Implementation of maximum correction of the current time up to ±29 sec. perhaps once a day.
