The series of electronic devices "Energomera" includes modern metering devices designed for use not only in everyday life, but also in industrial conditions. Electricity meters Energomera CE 101, for example, have long been included in the Register of measuring instruments, which is a legal basis for their use in power grids. Due to the ease of maintenance and reliability of the design, these devices are very popular with a wide range of consumers.
Description of the device
The energy meter is single-phase, as well as its three-phase modifications are capable of measuring the active and reactive components of the power consumed from the mains. In addition, with the help of Energomer's electricity meters, it is possible to organize an assessment of electricity consumption in a multi-tariff mode. This makes it possible to differentiate the metering of power consumed during the day or night, as well as during peak hours.
On the mounting block of most models of this class, along with switching contacts, there are special terminals for remote recording of readings. The connection of the telemetry output of the electronic meter CE 101, for example, is carried out through these contacts during its initial start-up. In addition, it has a built-in non-volatile memory unit. In the event of a loss of current in the supply line, the display records the last readings, as well as the date, time and tariff in which the device was operating before the voltage was removed.
There are also two LED indicators on the front panel of the CE 101 electric meter. The first one, designated as "Network", starts to glow when the electricity is connected. With the appearance of the load, it starts flashing; this means that the electronic accounting scheme has started to work.
If the LED under the “Network” marking does not light up, check the contacts on the connector terminals on the front panel. If everything is in order with them, and the indicator still does not light up, the device should be sent for repair.
The indicator window located next to it indicates the rating of the currently consumed power "600 imp / (kW-h)".
Specifications
Before choosing a specific model of the Energomer meter, it is imperative to familiarize yourself with the technical characteristics of the purchased device. Electric meter CE 101, for example, has the following technical characteristics:
- First class in accuracy.
- The number of provided tariff zones is one.
- The voltage for which the meter is designed is 230 Volts (50 Hz).
- Allowable forward current - 60 or 100 Amperes (depending on the model).
- The power consumed by the device itself from the network is 0.8 watts.
- The limit of permissible temperatures is from -40 to + 70 degrees.
- Weight - 0.495 kg.
The circuit for connecting the device to the serviced power network is straightforward, and in terms of the degree of protection against dust and moisture, it belongs to the IP5 class.
Service life of the device and calibration interval
For "Energomera" electric meters, the service life is determined by the conditions in which they are constantly used. This indicator may differ significantly from the parameter specified by the manufacturer in the technical specifications (up to 30 years). This difference sometimes reaches half of the specified period.
After a certain time interval that has passed since the start-up of the electric meter, the supplier's service is obliged to verify the device. The calibration interval for CE 101 devices, for example, is set in the range from 8 to 16 years, depending on the year of manufacture. The specific figure is usually indicated by the manufacturer in the passport of a three-phase meter.
Benefits of electricity meters
When considering the advantages of the range of products from "Energomer", it is noted that these devices are considered the highest quality of all samples on the market. The advantages include:
- High functionality of the product, capable of operating in several modes and storing the necessary information in memory.
- Convenience of taking readings, which, if desired, are transmitted to the dispatching console in automatic mode.
- Long warranty period (up to 30 years).
Due to the reliability of the accounting device, the probability of its accidental breakdown is minimized.
How to take readings
Before you start taking readings from the Energomer CE 101 electric meter, you should decide on the capacity of this device. The entire line of models of this class has 6 or 7 digits with a comma and an extreme right digit of a different color on the indicator.
The last sign highlighted in red means fractions of kilowatts that are not taken into account when taking readings. To obtain correct information, the user will need to rewrite all the numbers to the left of the comma. The written off number indicates the total consumption of electrical energy for the entire period of use of this meter. Thus, for modifications S6 and R5 of the CE-102 meter, only 5 digits should be recorded, and for the S10 model - 6.
To obtain the total, the user will have to subtract the readings taken last month from the previously recorded figures. This difference will correspond to the amount of consumed electricity for the reporting period. To get the result in monetary terms, you need to multiply the readings by the rate at the tariff for 1 kilowatt, set for the given region. For a two-tariff device, the procedure will become somewhat more complicated. In this case, you will need to record the readings for night and day time separately. To obtain the final result, you need to multiply the captured data by your “own” tariff, and then add up the two calculated values.
Counter varieties
To describe the existing varieties of devices from the "Energomera" line, it is enough to mention the following models:
- CE101.
- TsE6803V.
- TsE6803VM.
- TsE68038 and others.
In addition to this division, the TsE6803V models, for example, are distinguished by the method of fastening a specific sample within the cabinet. In accordance with it, products are marked with alphanumeric characters: R31, R32 or Ш33. The presence of codes R31 and R32 on the device means that there are special fasteners on its body, by means of which it is attached to a DIN rail.
A DIN rail type guide is made in the form of a metal profile with a longitudinal groove.
Products marked with Ш33 mark are fixed inside the cabinet or panel using a special anchor fastening consisting of three bolts. On the back wall of the meter, special fastening loops are provided for this purpose.
Features of installing the counter
When familiar with the various models of the Energomer line, the connection of the meter to the mains is considered separately. This is due to the fact that the correctness of this procedure depends not only on the correctness of charging for the consumed energy, but also on the performance of the meter itself.
It is allowed to start connecting the device only after all the necessary permits for this procedure have been drawn up.
The installation instructions for the device are as follows:
- Representatives of Energosbyt send technical documentation to the consumer, indicating the type of electricity meter. It also contains the rating of the circuit breaker, as well as the cross-section of the supply wires and the method of fastening (on the wall of the shield or on a DIN rail).
- A local electrician or specialist from the provider installs the meter on site and conducts a test connection to the network.
- The same person will seal the device, after which an act of delivery and commissioning is drawn up.
The final document is signed on the one hand by the representative of Energosbyt, and on the other, by the consumer of electricity.
Electricity meters from the Energomera line, including three-phase devices, are distinguished by their versatility and increased functionality. This is manifested in the ability to use the device in a wide variety of areas of economic activity related to the consumption of electricity. The products of this group have been familiar to users for more than a dozen years and have proven themselves during this time only from the good side.
