When choosing an electricity meter, the consumer should pay attention to many different factors. On the market today, there are metering devices of both sufficiently high quality and deserving not too good consumer reviews. Of course, when buying such equipment, first of all, you should pay attention to the brand of its manufacturer. For example, SOE-55 is considered a very good counter. Models of this brand have passed all the necessary tests, are recognized as suitable for use as metering devices, including in domestic conditions, and are distinguished by very good build quality.
General description of the device
ESR meters of the 55 series are produced by a plant owned by CJSC MZEP, located in Moscow. They belong to the class of household equipment and are intended for use in two-wire alternating current circuits with a frequency of 50 Hz. Among other things, these devices are also adapted to work in automated information-measuring systems of ASKUE. Some modifications of SOE-55 meters (in case "2") can be installed on a DIN rail or under the cover of the controller or modem terminal.
Featuresdesigns
These single-phase meters are built on an elementary modern base using high-speed electronic memory. Among other things, modern microprocessors are used in their design. There are modifications of ESR-55 on the market today:
- with one or two current sensors (used to prevent theft of electricity);
-
with built-in relay to turn off the consumer.
Information about the amount of electricity used in these meters can be displayed on an electromechanical device or on a liquid crystal display. Devices of the first type have the letter “M” in the marking.
Varieties
If you wish, you can purchase an ESR-55 meter today:
- one-tariff;
- two-tariff (with external tariff);
- multi-tariff.
Meters marked "ShT" are most reliably protected from the most common ways of distorting readings by penetrating into the wiring diagram or by exposure to an electric field. Local communication in these models is carried out using a special optical port. The printed circuit board in all SOE-55 meters is mounted using a special SMD technology. These devices are attached to the support with three screws.
Benefits: Electricity Supplier Reviews
Workers of power supply services to the pluses of SOE-55 meters are primarily:
- presence of protection against the most common methods of theft;
- large technological margin of accuracy;
- possibility to remotely turn off the consumer or reduce power if necessary.
To work as a part of ASKUE, these meters have special electronic interfaces RS-232 or RS-485, as well as a special output. The last design element is designed to prevent the loss of pulses during power surges.
Consumers also consider these counters to be of sufficient quality. The advantages of the models of the owners of houses and apartments include:
- resistance to low temperatures;
- high build quality;
- durability of transformer connection;
- vibration resistance;
- long service life.

It is allowed to use the SOE-55 electric meter in domestic conditions for 16 years. After that, it must pass the appropriate check or be replaced. In total, the 55 series ESR devices can, according to the manufacturer, last 36 years. According to the method of protecting the consumer from electric shock, they correspond to the second class (according to GOST 8865-93). The MTBF for these models is 140,000 hours.
What sizes can the model have
Today there are only three main types of ESR meters of the 55 series on the market:
- In case "0". The overall dimensions of the devices of this group are 210x137x65 mm;
- In case "1". This model is marked SOE-55/50-112. The case of meters of this modification has dimensions of 210x137x115 mm.
- In case "2". The dimensions of such meters are 213x131x83 mm.
Modifications of SOE-55/60 Sh-T-112 are also supplied to the market today. The case of these counters is marked with the number "0". They have the following dimensions: 210x137x65 mm. In any version, therefore, the ESR meter is compact. And therefore, finding a place for him in an apartment or a private house will be completely easy. For this, of course, these devices also deserve good reviews.
SOE-55: instructions for use
The service life of ESR-55 meters is therefore significant. However, this equipment can last a long time, of course, only if it is properly used. If necessary, the meter can be used at an ambient temperature of -40 to +60 C. The model can, of course, be operated around the clock. The relative humidity of the air in the room in which the meter will be installed should not exceed 98% at a temperature of 25 C. Such a high rate is allowed, however, only if there are no various kinds of aggressive gases and a large amount of dust in the air. In any case, this counter can also be installed in wet rooms, for example, in a free-standing bath. Of course, it is allowed to mount this equipment in street accounting boxes.
What are the disadvantages
Of course, ESR-55 meters have more than just pluses. They also have certain disadvantages. These include, for example:
- uncomfortable mounting method;
- brittle plastic terminal box cover.
The design of this meter is such that when connecting its main wire, unfortunately, it can be accidentally damaged. Therefore, include it in the network diagramshould be done as carefully as possible. All wires should be bent in advance.
Also, the disadvantages of SOE-55 counters include the not very reliable electronic part. Often (and especially when used outdoors) it happens that during a thunderstorm it fails. The same thing can happen with a short circuit in the network. This counter, meanwhile, is worth in the region of 1000-1500 r. It certainly isn't too expensive. But still, even such an amount lost due to a breakdown of the device will definitely affect the family budget.
Consumer Opinion
Despite some of the shortcomings of SOE-55 meters, reviews from homeowners, members of gardening associations, etc., as already mentioned, they deserved relatively good ones. Two-tariff meters of this brand are especially popular with owners of houses and apartments. The main advantage of such modifications, in addition to compactness, the owners of houses and apartments consider the possibility of saving. Indeed, at night in many cities of the Russian Federation and the countries of the former CIS, electricity costs almost half as much as during the day. Therefore, having such a counter, you can save quite a significant amount.
Can the device overestimate readings on its own
The accuracy class of the ESR-55 model, as already mentioned, is the first. Thus, he always calculates the amount of electricity correctly. However, sometimes, judging by consumer reviews, this device can still “fail”. According to the manufacturer, the defective rate for these meters is 0.3%. Therefore, the first time behind the readings of the device isfollow more closely. In order to check the accuracy of the number displayed on the counter display, you should perform a couple of simple steps:
- memorize or write down readings;
- unplug all electrical appliances from sockets.
After ten minutes, you need to check the readings again. During this time, they should not change in any way. The LED on the instrument itself should also not flash during this period of time.
In case of cheating, no independent actions, of course, should be taken. In order to remedy the situation, you must immediately call the house management and call electricians. The latter will remove the seal and first check whether the device is correctly included in the circuit. If no errors are found, electricians, at the request of the owners of the property, can take the device for verification (for a fee). But most owners of apartments and houses advise in this case to simply buy a new meter. It will cost, most likely, even cheaper than checking. In addition, the electricity in the house will be connected much faster if there is a new appliance.
