The Energomera series of electronic devices includes modern metering devices designed for operation not only in everyday life, but also in industrial conditions. Electric meters Energomera CE 101, for example, have long been included in the Register of measuring instruments, which is the legal basis for their use in electric networks. Due to the ease of maintenance and reliability of the design, these devices are very popular among a wide range of consumers.
Product Description
The Energomer 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, by means of energy meters, Energomera manages to organize an estimate of the energy consumption in multi-tariff mode. This allows you to differentiate the account 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 reading of readings. The connection of the telemetric output of the CE 101 electronic counter, 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 power failure in the supply line, the latest readings are recorded on the display, as well as the date, time and tariff at which the device worked before the voltage was removed.
On the front panel of the CE 101 meter, there are also two LED indicators. The first of them, designated as “Network”, starts to glow when electricity is connected. With the advent of the load, it starts to blink; this means that the electronic accounting scheme has started to work.
If the LED marked “Network” does not light up, you should check the contacts on the terminals of the connector on the front panel. If everything is okay with them, but the indicator still does not light, the device should be sent for repair.
The adjacent indicator window indicates the nominal power consumption of “600 imp / (kW-h)”.
Specifications
Before choosing a specific model of the Energomer meter, it is necessary to familiarize yourself with the technical characteristics of the purchased device. The CE 101 electric meter, for example, has the following technical specifications:
- First class for accuracy.
- The number of tariff zones provided is one.
- The voltage for which the meter is designed is 230 Volts (50 Hz).
- Permissible direct current - 60 or 100 Amperes (depending on 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 diagram for connecting the device to the mains is direct, and in terms of protection against dust and moisture, it belongs to IP5 class.
Instrument life and calibration interval
For electric meters of Energomer, the service life is determined by the conditions in which they are constantly operated. This indicator may differ significantly from the parameter set by the manufacturer in the technical conditions (up to 30 years). This difference sometimes reaches half the specified period.
After a certain period of time that has elapsed since the commissioning of the electric meter, the service of the supplier is obliged to carry out calibration of the device.The verification interval for CE 101 devices, for example, is set within the range of 8 to 16 years, depending on the year of manufacture. A specific figure is usually indicated by the manufacturer in the passport of a three-phase meter.
The advantages of electricity meters
When considering the advantages of the product line from Energomera, it is noted that these devices are considered the highest quality of all the samples on the market. The advantages include:
- High functionality of the product, able to work in several modes and save the necessary information in memory.
- Convenience of taking readings, which, if desired, are transmitted to the control panel in automatic mode.
- Long warranty period (up to 30 years).
Due to the reliability of the accounting device, the probability of its accidental failure is minimized.
How to take readings
Before proceeding to take readings from the electric meter Energomera CE 101, you should determine the bit depth of this device. The entire line of models of this class on the indicator has 6 or 7 digits with a comma and the rightmost digit of a different color.
The last highlighted red sign indicates fractions of kilowatts, which are not taken into account when taking readings. To get the 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 time that this meter has been used. Thus, for versions S6 and R5 of the CE-102 counter, only 5 digits should be fixed, and for model S10 - 6.
To get the final value, the user will have to subtract the readings taken last month from the previously recorded digits. 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 rate of 1 kilowatt established for this region. For a two-tariff device, the procedure will be somewhat more complicated. In this case, you need to record the readings for night and day time separately. To get the final result, you need to multiply the captured data by “your” tariff, and then add up the two calculated values.
Varieties of counter
To describe the existing types of devices from the Energomera line, it is enough to mention the following models:
- CE101.
- CE6803V.
- CE6803VM.
- CE68038 and others.
In addition to this division, the CE6803B models, for example, are distinguished by the method of attaching a specific sample within the cabinet. In accordance with it, products are marked with alphanumeric characters: R31, R32 or Ш33. The presence of the code R31 and R32 on the device means that there are special fasteners on its body through which it is mounted on a DIN rail.
A guide rail of the din rail type is made in the form of a metal profile with longitudinal notch.
Products marked with the Ш33 symbol are fixed inside the cabinet or shield using a special anchor fastening consisting of three bolts. On the back wall of the meter, special fixing loops are provided for these purposes.
Features of installation of the counter
When getting acquainted with the various models of the Energomer line, connecting the meter to the mains is considered especially. This is due to the fact that not only the correctness of charging for the consumed energy, but also the performance of the meter itself depends on the correctness of this procedure.
It is allowed to start connecting the device only after all permits required for this procedure are completed.
Instructions for installation of the device are as follows:
- Representatives of Energosbyt send technical documentation to the consumer indicating the type of meter.It also specifies 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 the DIN rail).
- A local electrician or specialist from the provider sets the meter in place and conducts a test connection to the network.
- The same person seals the device, after which an act of commissioning and putting it into operation is compiled.
The final document is signed on the one hand by the representative of Energosbyt, and on the other, by the consumer of electricity.
Electric 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 business areas related to electricity consumption. The products of this group have been familiar to users for more than a dozen years and have established themselves during this time only on the good side.
