Electronic Energy Meter Features

① powerful, easy to expand.
An electronic energy meter is equivalent to a few induction meter, such as a full-featured electronic multifunction meter is equivalent to two positive active table, two positive reactive table, two largest scale and a only the loss of pressure chronograph, and can achieve this seven tables can not be achieved hourly metering, automatic meter reading data and other functions. At the same time, reduce the number of meter, effectively reducing the secondary circuit pressure drop, improves the reliability and accuracy of the metering device.
② high and stable level of accuracy.
Induction meter level of accuracy is generally 0.5 to 3.0, and due to mechanical wear and tear,  Electric energy meter , and electronic energy meter can easily use a variety of compensation easily reach a higher level of accuracy, stability and error good, electronic energy meter level of accuracy is generally 0.2 to 1.0.
③ starting current is small and the error curve flat.
Induction meter to 0.3% Ib measured to be up and down, the error curve is large, especially in the low load larger error; while electronic energy meter is very sensitive, at 0.1% 1b can be initiated and carried out under the measured, and the error curve is good, the error in the whole load range is almost a straight line.
④ wide frequency response range.
Induction meter frequency response range is generally 45 ~ 55Hz, while the electronic multi-function table of frequency response range of 40 ~ 1000Hz.
⑤ little influence by the external magnetic field.
Induction meter is based on the principle of moving into the measured magnetic field, so the external magnetic field on the meter metrological performance greatly. And  Electric transformer on electronic meter multiplier for computing, the measurement of performance by external magnetic fields smaller.
⑥ easy to install and use.
Induction meter installation, there are strict requirements, if hanging horizontal  power transformers deviations, even obvious tilt will cause energy measurement inaccurate. The electronic energy meter is used in electronic metering mode, no mechanical rotating parts, so there is no such problem, and its small size, light weight, easy to use.
⑦ overload capacity.
Induction meter is the use of the work coil, in order to ensure its measurement accuracy, generally only overload four times; while electronic multifunctional table can reach 6 to 10 times overload.
⑧ tamper stronger.
Stealing electricity in urban and rural areas is an unavoidable reality, induction meter tamper capability is poor. The new electronic power meter from the basic principle to achieve a common to prevent tampering. For example, ADE7755 through two current transformers were measured phase line, zero line current, and in which a large current basis as energy metering, enabling to prevent the short circuit current conductors, etc. stealing ways.
