Electricity meters have so many ways to supply electricity

Electricity meter is used to measure the electrical energy meter, also known as electricity meter, live meter, kilowatt hour meter. Electricity measurement is an important part of the production and operation activities of power enterprises and the safe operation of the power grid. Trade settlement, assessment of the power system economic and technical indicators are dependent on accurate and complete electrical energy measurement device. The performance and management level of electric energy meter is not only related to the development of electric power industry and the image of electric power enterprises, but also affects the accuracy and fairness of trade settlement, involving the fundamental interests of the majority of electric power customers.

   For the general public, the energy meter is both familiar and unfamiliar, they all know that they have used the energy meter at home, but most people have never cared about this energy meter. There are many kinds of energy meters, different countries and regions have their own requirements, yongtailong as an energy meter export manufacturers, customers in more than 60 countries and regions, the design and development of the type of meters manufactured is more diverse.


From the perspective of power supply, I would like to introduce you to the classification of energy meters, which can surely bring you a sense of novelty.

Note: Live line L, neutral line N


Single-phase two-wire energy meter, (220V or 110V),The voltage between the live line and neutral line is 220V~230V in 4/5 countries around the world, and 110V in some countries, such as the United States and Japan. Single-phase energy meter is used for residential users' electricity metering and charging, which is large and extensive, directly related to the interests of thousands of households, and also related to the stable and safe operation of the power sector.

Single-phase three-wire energy meter (120/240V),2 live lines L, 1 neutral line N,Between neutral line and live line is 120V,Between the neutral line and the live wire is 120V, and between the live wire and the live wire is 240V.
Single-phase three-wire meters are used in the Philippines, Japan and Taiwan.








Two-phase three-wire energy meter (2*120/208V),
2 live wires, 1 neutral line,120V between neutral line and live wire,between neutral and live wire is 120V, between live wire and live wire is 208V.
South America will use two-phase three-wire meters.





Three phase three wire energy meter (3*100V),
3 live wires without neutral lines.Triangular connection,100V between the live wires,Used in power generation, transmission and substation high voltage side, PT and CT are needed when using.







Three-phase four-wire power meter, (3*220/380V),
smart three phase Power meter,3 live wires, 1 neutral line,Star connection,220V between neutral line and live wire,Between the live wire and the live wire is 380V. Mostly used for industrial electricity or large users.







DC power meter,
Mostly used in new energy power generation, telecommunication base stations, subways, DC charging piles and other applications, with the development of new energy generation and electric vehicles, the amount of DC meters is also growing rapidly.

 


With the progress of science and technology, the manufacturing and design level of energy meter has been improved, from the original common electronic energy meter to multi-functional energy meter (prepaid, compound rate), smart meters and other types to meet the growing market demand; yongtailong was founded in 1995, and has experienced various stages of energy meters. The market demand is still the largest for common single-phase energy meter, three phase kWh meter ,single-phase multi-function meter and smart three phase kWh meter.
