Electric meter. Single-phase and three-phase meters

Are you interested in single-phase and three-phase electricity meters from the supplier — the company AvecGlob? Here you will find interesting information on this topic.

Appointment

Electric meters as measuring devices are used to measure the amount of electricity supplied or used for a certain period of time. Compact measuring instruments are designed as modular devices for alternating current, and can be installed in the home and at work. In the latter case, electric meters are also used to measure pulses in control systems and automation, powered by alternating current. The time and pulse counters are used to reliably monitor the production and maintenance times, which allows you to accurately plan and control the production sequence, maintenance cycles and warranty time.

Electric meters are used to measure kWh energy in single- and three-phase systems, for example. at industrial enterprises, in offices and apartments in apartment buildings. They help to minimize operational costs and facilitate cost allocation.

Single-phase meters

Typical features of these devices are:

Use of digital technologies based on microcontrollers;

Low inertia during start-up;

Low self-energy consumption;

The correct determination of the amount of energy, regardless of the external conditions of use (for example, with external exposure to electromagnetic fields);

LED indication;

Protective fencing;

Absence of mechanical wear of components.

Supplier — AvekGlob Company — offers at a reasonable price from the manufacturer a diverse range of AC electric meters manufactured using precision nickel based alloys. The supplier guarantees the timely delivery of products to any address specified by the consumer.

Three-phase counters

To connect, very often, powerful electrical appliances are required to be connected to a three-phase network. Advantages of the three-phase system are as follows:

The absence of influence of voltage drops on the accuracy of measurements. In a normal network, when high load is switched on, voltage fluctuations and electrical noise occur. In a three-phase network, vulnerable devices and equipment can be fed from a separate phase;

With a break in one phase, you can connect consumers to the remaining, while, for example. A phase motor will consume less energy.

Operating principle

A single-phase meter has two coils, one of which enters the row (ampere), the other in parallel (volts), generates induction eddy currents in an aluminum disk, the electromagnetic interaction causes it to rotate and transmit this rotation to the counting mechanism. In a three-phase meter, energy consumption measurements take place for each individual phase, and the total readings are added.

Thanks to the appearance of electronic devices for electricity metering, it was possible to create a two-tariff meter. It is known that at night the energy consumption is much lower than at peak times. This is true for both the individual user and the whole power system. Modern electric meters are also produced in a two-tariff version.

Supplier — AvekGlob company — offers to purchase various sizes of single-phase and three-phase electricity meters, which are manufactured using precision nickel-based alloys. Products can be bought at a price formed on the basis of European and world standards of production. Implementation is possible in bulk and retail, for regular customers, a flexible system of discounts operates.
