Zhejiang Tianpusheng Electric Co., Ltd. is one of the largest manufacturers of electric energy meters in Taizhou City, Zhejiang Province, China. One of the products we promote is electronic energy meter. If you are interested in us, please contact us:https://www.yhddb.com/ 。Here is a brief introduction to the advantages of electronic energy meter:
①Powerful function and easy to expand
An electronic watt-hour meter is equivalent to several induction watt-hour meters. For example, a fully functional electronic multi-function meter is equivalent to two positive active meters, two positive reactive power meters, two maximum demand meters and Only the loss-of-pressure chronograph can realize the functions of time-sharing measurement and automatic data reading that these seven watches cannot. At the same time, the reduction in the number of meters effectively reduces the pressure drop of the secondary circuit and improves the reliability and accuracy of the entire metering device.
②High accuracy and stability
The accuracy level of induction watt-hour meters is generally 0.5 to 3.0, and the error is prone to change due to mechanical wear, while electronic watt-hour meters can easily use various compensations to easily reach a higher accuracy level, and the error is stable The performance is good, and the accuracy level of the electronic energy meter is generally 0.2 to 1.0.
③The starting current is small and the error curve is flat
The induction electric energy meter can be started and measured under 0.3% Ib, and the error curve changes greatly, especially when the load is low; while the electronic electric energy meter is very sensitive and can start and perform measurement under 0.1% 1b. Metering, and the error curve is good, the error is almost a straight line in the full load range.
④Wide frequency response range
The frequency response range of the induction electric energy meter is generally 45-55 Hz, while the frequency response range of the electronic multi-function meter is 40-1000 Hz.
With the comprehensive advantages of price, quality and technology, the company’s products can be seen everywhere. If you are interested in purchasing our products, please click on the link to contact us: single phase meter manufacturer.
