The Mercury 230 counter can be used with equal success in everyday life and for industrial purposes. This device is a frequent guest in luxury cottages containing a large number of various electronics, from refrigerators, washing machines and ending with underfloor heating.

You may also be interested in what methods of transmitting electricity readings exist. And if the resulting numbers are too large, you should think about saving, which you can read about.

There is a special modification for transformers that can work autonomously or in conjunction with an automated electricity consumption control system.

Design description

The Mercury 230 direct-flow meter works on the same principle as other devices of this kind: it receives signals from special sensors and translates them into the language of power and energy.

The user can, at will, read the data both directly from the device itself and remotely.

The design of the device includes the following elements:

• frame;
• measuring device;
• terminal block and cover.

Current transformers and resistive dividers are the first to pick up incoming signals. Then the information is received and converted into a digital code by the microprocessor. Thanks to this, the equivalent of the consumed power is displayed. Another function of the processor is to control the electrical units of the meter.

Specifications

It does not make sense to list the characteristics of the model in full, since it will take a lot of time. It is worth noting especially important parameters:

1. Accuracy class. This indicator determines the percentage of instrument error. The larger it is, the less reliable the mechanism is considered. The Mercury 230 electric energy meter has an accuracy class of 0.5, which is an excellent indicator.
2. Rated voltage - 3 * 57.7 per 100 V. Maximum current - 5 A.
3. Dimensions - 258 by 170 by 74, weight does not exceed 1.5 kg.
4. Operating temperature - almost any, from -40 to +55 Celsius.
5. Additional features. The device has burglary protection, there is a seal on the front panel. The meter can diagnose its own problems and generate an error.

Many technical characteristics (rated voltage, max current, etc.) depend on the specific model. Description Mercury 230 differs markedly from simpler models.

Basic and advanced features

The set of functions also depends on the chosen modification (see below). In this case, the list of basic and additional functions is given in the form that is typical for Mercury 230 ART models:

Modifications

Descriptions of Mercury 230 meters would not be complete without mentioning modifications. The series is distinguished by a large number of modifications, as different areas of application require additional functionality. It is not possible to fit them into one model. Yes, and the cost of such a device will be exorbitant.

Here are some model modifications:

1. Mercury 230 AM. The device offers accounting in a single tariff mode, assuming only an increase in data from the moment the device is put into operation. The device can be used offline and in the ASKUE system.
2. Mercury 230 AR. The model offers consumption accounting for a separate phase or as a whole. The meter "cooperates" with CAN, RS - 481 interfaces. Another advantage of the model is a programmable phase summation mode, which will prevent cases of electricity theft.
3. Mercury 230 ART. In this case, there are several modifications, among them is the Mercury 230 ART 01 electric meter. It is distinguished by a wide range of additional functions that will allow you to buy what the user specifically needs.

The three-phase counter Mercury 230 is a device of new release. This device has telemetry outputs and a special interface designed for information exchange. An electronic seal is installed on the device, the device can carry out automatic diagnostics of various malfunctions. The manufacturer of electric meters is the company "NPK Incotex".

Device Description

A direct-flow meter Mercury 230 is installed to account for electricity in three-wire and four-wire networks. The device can be connected either by direct or transformer method. If a transformer is connected to the device, then it will be possible to take into account electricity at objects with a high load.

The device, which has three phases, has a liquid crystal display. This screen displays data in kilowatt-hours. The display has 8 digits. The first 6 digits show integer values ​​of kWh, the last 2 - decimal places, hundredths of kWh. The error that exists in the readings of this device is 1.0. Devices are installed indoors, where the air temperature can be -40 ... + 55ºC.

If the device is connected through a transformer, then it is possible to measure a current greater than that for which the device is calculated. Counters are mounted in the domestic and industrial sectors. Household appliances are installed in residential buildings. Industrial appliances are used in the industrial sector, in businesses, factories and plants. Counters are induction and electronic. Electronic ones have a high quality certificate, are more accurate, they do not have rotating parts and convert the signal that comes from the measuring elements.

Specifications

The electronic counter Mercury 230 differs in the increased accuracy and high reliability. The smallest operating time is 150 thousand hours. Duration of operation of the device - 30 years. The terms of verification of electric meters (inter-verification interval) are 10 years. The warranty period is 3 years from the date of manufacture.

Specifications:

1. The rated current for the transformer connection is 5 A.
2. The base current for direct connection of the device is 5 A or 10 A.
3. The highest current strength is 60 A.
4. The phase voltage indicator is 230 V.
5. Frequency -- 50 Hz.
6. 2 pulse output modes: basic, verification.
7. The limit of permissible error of the device refers to accuracy class 1.
8. Dimensions, dimensions: 258x170x74 mm.

When there is no current in the series circuit, the instrument's test output, when measuring active and reactive energy, does not generate more than one pulse per 10 minutes. These devices are highly durable and reliable. Previously, they were installed at manufacturing enterprises. Now they are often used when wiring electricity in country houses. This is due to the presence of a large number of household appliances, which require a high power supply.

Basic and advanced features

Now electric meters, in addition to the main function - electricity metering, have various additional properties, with the help of which it is permissible to control some of the characteristics of the electrical network and the modes of the device itself. You can take data from this device not only at the place of operation, but also remotely through some types of interface. The Mercury two-tariff meter is a device that has enhanced capabilities.

Standard connection options for a three-phase meter Mercury 230:

1. Measurement of electricity data, their storage and visualization on the display for such a time interval: from the last reset, 24 hours, 30 days, a year.
2. The device can take into account the current according to two tariff plans for 16 time zones.
3. The device can be programmed every month for a new tariff.

The device records the following characteristics:

• instant power calculation;
• determination of potential difference;
• definition of current by phases;
• network frequency indicator;
• power in different phases and total.

The device has maximum protection. If the limit is exceeded, the device notes this, the exact time when the excess occurred is also indicated. The digital output allows you to control the load.

The machine has an event log. It contains the following indicators:

• the time of connecting the device to the network and disconnecting from it;
• phase accounting;
• adjustment of the tariff schedule;
• accounting for the opening of the counter;
• exceeding the limit.

Consider additional features of the device. The counter has additional functions:

• electricity metering in forward and reverse directions;
• it is possible to transfer data on the consumption of electricity for each phase;
• the presence of an archive of power data with an interval of 1 to 45 minutes;
• the archive data storage period is 85 days;
• the highest indicator of morning and evening power;
• accounting for losses;
• accounting for magnetic impact with data recording in a special journal;
• power quality control.

Wiring diagram

Consider how to connect the device. You can connect the meter according to different schemes, in which current transformers will be used as a data source. Here is a connection diagram for the Mercury 230 meter. The most common is a ten-wire connection diagram for the device. Its advantage is the presence of power circuits and measuring instruments. The disadvantage is a large number of wires.

The sequence of connecting the meter and transformer:

• terminal 1 - input A;
• terminal 2 - input of the end of the measuring winding A;
• terminal 3 - output A;
• terminal 4 - input B;
• terminal 5 -- input of the end of the measurement winding B;
• terminal 6 -- output B;
• terminal 7 -- input C;
• terminal 8 -- winding termination input C;
• terminal 9 -- output C;
• terminal 10 -- zero phase input;
• terminal 11 -- zero phase on the voltage side.

To install the meter in a break in the transformer circuit, terminals L1 and L2 are used. You can connect the meter using a semi-indirect circuit. In this case, the current transformers are connected to a star. Then the installation of the device is facilitated and less wires are needed. The accuracy and quality of the data does not deteriorate.

A seven-wire method for connecting a TT is also used. Its disadvantage is the lack of galvanic isolation of circuits. Such a scheme is considered dangerous to use and is now almost never used.

Connecting an electric meter Mercury 230 has much in common with installing a single-phase device. But there are many differences in the installation of the installation. The connection diagram is available on the meter body, on the reverse side of the cover.

During installation, the color sequence must be observed. Even numbers of wires correspond to the load, odd numbers - to the input. Three-phase multi-tariff meter connection schemes are used.

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-on meters do not exceed 100 A. This is due to the limitation of the conductor dimensions. The higher the current, the larger the cross section of the wire is needed to pass it. Such limitations are eliminated by current transformers.

Consider the connection diagram of the meter through the test terminal box: the terminals in the block are designated by the letters A, B, C. A wire comes to these terminals, which is connected to the 380 V power buses, and then goes to the meter through jumpers.

If necessary, the jumpers are untwisted, shifted, and the chain is broken. This can remove the mains voltage and ensure the safe operation of the device connected to the test box. ICC has a protective cover and a sealing device, a screw with a hole. The installation of the seal is carried out together with the installation of the meter.

Consider how to take readings of the electricity meter. The device has a 6-digit dial. It is necessary to write out all the numbers up to the decimal point. To calculate the energy consumption for the month, it is necessary to subtract from the new readings those that were last month.

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

There should be a line near mark A. If not, then press the right button. Then press the Enter button. In this case, the display will show the current consumption data for the day T1. Press Enter a second time and overwrite the value of T2 (at night).

Modifications

There are such modifications of Mercury counters:

1. Single tariff three-phase, multi-tariff and multifunctional: Mercury 230 ART, Mercury 231 AT.
2. Three-phase active and reactive electrical energy single tariff, article: Mercury 230 AR.
3. Three-phase active energy single tariff: Mercury 230 AM, Mercury 231 AM.
4. Single-phase active energy, single-tariff and multi-tariff: Mercury 200, Mercury 202, Mercury 201.

The SIKON controller is installed in Mercury meters with active and reactive energy with an internal rater, the devices can be bidirectional or unidirectional.

The energy that is used to feed electrical appliances and various kinds of equipment, as you know, is rapidly becoming more expensive and requires accounting and control of consumption. For this purpose, energy metering devices - electric meters - are installed in the premises.

This article will discuss the benefits of using and characteristics of the Mercury 230 ART 03 meter. However, before proceeding with the analysis of this equipment, some points should be clarified.

Which counter to choose

A single-phase electricity meter is installed in a two-wire network with alternating current and a voltage of 220 volts. Three-phase controls consumption and takes into account electricity, however, it works on the basis of three-wire (and four-wire) networks with a frequency of 50 Hz, with alternating current and a voltage of 380 volts.

A much more complex apparatus is a three-phase meter. It is installed to control the energy consumption in industrial buildings, factories, factories and other enterprises where a large amount of electricity is consumed.

If there is no neutral wire in the building, a three-wire meter should be taken; if there is a neutral wire, a four-wire meter should be used.

Three-phase measuring instruments of the Russian company "Mercury" are produced by the well-known company "NKP" Incotex. Among 120 varieties, there are both simple single-phase and the most complex multi-tariff devices, with the ability to control the load and transmit measurements to remote devices.

Three-phase counter Mercury 230 single tariff

One of the most uncomplicated devices can be called a single-tariff three-phase meter Mercury 230. Such an electrical meter is offered for operation by users who have three- or four-wire AC networks.

It works well in tandem with equipment designed for automatic regulation of electricity. The 230 ART 03 series meter is one of the metering devices for electricity consumption in AC networks. It is used both for economy and convenience.

The functioning of electric meters is based on the transformation of signals from devices for fixing current and voltage into numbers on a liquid crystal screen. Data from such devices can be taken both in direct contact and at a distance using built-in programs.

Application of the counter Mercury 230

Mercury 230 ART 03 is used both in industry and production, and in everyday life. It can be found in private houses and dachas, where electrical appliances operate that consume large amounts of energy, such as boiler rooms, floor heating, outdoor lighting and other energy-volume systems that consume this resource.

Additional tasks

In addition to electricity metering, this device performs many additional configurations, including accounting and storing data on the electricity used for a specific time period, taking into account the tariff schedule in a multi-tariff mode.

Activating a multi-tariff or two-tariff mode guarantees savings by using different tariffs for 24 hours. It is not always necessary to use tariff 4; for domestic needs, it is enough to install a two-tariff electricity meter.
