Electricity meter ЦЭ6803 В is an electromagnetic device with elements of microprocessor technology. It is designed to calculate the electrical energy that was consumed by the consumer. The device is being manufactured by Energomera concern. Due to its low cost, the device is popular. It should also be remembered that the TsE6803 B intertesting interval is 16 years.

Purpose of the device
Energy meter TsE6803 V allows you to measure the active component of the consumed power. The device was entered in the register of measuring instruments and can keep records at one tariff.
This fact suggests that it cannot be used to separately calculate energy in the daytime and at night in accordance with the tariffs of the organization supplying electricity.
The device can be connected using three or four conductors. In the second case, not only the phase conductors are involved, but also the neutral wire. It is also possible to connect directly or indirectly (using transformers) to a network with a frequency of 50 Hz.
Installation of the device on the street is allowed, but only in cabinets that prevent dust or moisture from entering the meter.When installing the device, the following requirements must be observed:
- The operating temperature range should be -40 to 60 degrees.
- The air humidity indicator cannot be higher than 98%.
Subject to all operating conditions and correct connection to the mains, the service life of the device is 30 years. The manufacturer provides a four-year warranty for its product from the moment the meter is put into operation.
Decoding of marking
GOST is indicated on the front panel of the device, in accordance with which it was manufactured. Each series of the meter has certain requirements for operation, as well as technical characteristics. All important information is indicated on the labeling of the device. As an example, we can take the model TsE6803V / 2 1 T 110 V 1-7.5A 3ph.4pr. M6 Sh33.
Its designation is deciphered as follows:
-
2 - defines the accuracy class of the device. - 1 T - the meter takes into account the consumption of electricity in accordance with one tariff.
- 110V - the nominal voltage of the device is 110 volts.
- 1-7.5A - the maximum current is 7.5 A.
- 3f.4pr - diagram of connecting the device to the network.
- M6 - indicates the type of reader, in this case six-digit mechanical.
- Ш33 - the method of mounting the device and the type of housing. The model in question must be mounted on a shield.
Working principle and design
The Energomera enterprise also produces a modified version of the meter - TsE6803VM. The main differences between these devices are in a more advanced element base, improved protection against burglary and theft, as well as a new protective system against underestimation of electrical energy. The principle of operation of the meter consists in determining the active power of the consumed energy by multiplying the indicators of the current strength and voltage of the consumed energy. Then the device generates an impulse, which is transferred to the electricity metering mechanism.
The meter body is made of plastic. After mounting the device, a seal with a proof stamp must be installed on it. This procedure should be carried out by employees of the electricity supplier or energy saving company.
The installation of the device can be carried out by the consumer independently, but checking and sealing is carried out by employees of the relevant organizations.
Before purchasing the device, it is worth studying the technical characteristics of the CE6803 V meter. The device is designed to operate in a network with a frequency of 50 to 60 Hz. The rated current is 5 A, and the maximum is 60 A. All other parameters can be found in the passport TsE6803 V.
Installation and connection
Before installing the device, it is necessary to check the device for mechanical damage and the presence of seals. Also you need to pay attention to the method of fixing the device - on a DIN rail or a shield using a bolted connection. The CE 6803 meter can be connected to the power grid directly or using transformers. It should be remembered that when connecting the device, the power voltage must be disconnected.
Transformers are necessary if it is necessary to measure the power of the consumed energy in a circuit where the voltage and current indicators are higher in comparison with the meter. The simplest is the direct connection circuit. When connecting devices, you need to carefully strip the ends of the conductors. The exposed part of the wire must be flat and inserted into the terminal without distortion. After that, first tighten the upper clamping screw, and then the lower one.
This device is a fairly reliable means of accounting for consumed electricity. It can be used not only in domestic but also in industrial environments. If a malfunction is detected in the operation of the meter, you must immediately call a representative of Energonadzor.
