The electronic electricity meter has become the mainstream power consumption measurement device in today's society. With the development of electronic technology, the function and performance of electronic electricity meters have been greatly improved. The functions have been enhanced in terms of human-computer interaction and management control, while the accuracy class, anti-interference ability, and lifespan have also been significantly improved.

1. Stability of electronic electricity meter

Electronic electricity meters use hundreds or thousands of electronic components based on their complexity and intelligence, and any deviation in these components can impact the performance of the meter. In the early days of the birth of electronic electricity meters, the technology of electronic components was also relatively backward. The discrete type of devices required inefficient and complex production and processing technologies to ensure their quality. With the advancement in electronic technology, the reliability and maturity of electronic components are increasing day by day. This serves as a foundation for the stability of electric energy meters. In order to ensure the stable and reliable operation of electronic electricity meters after entering the market, manufacturers carry out high-temperature aging during the production process. This allows the product to enter a stable period on the electronic product bathtub profile.

2. Accuracy of electronic electricity meter

As a basis for measuring power consumption and calculating charging fees, electronic electricity meter are closely related to people's livelihood issues. The accuracy of power measurement is very important in this context. The energy meter class is 0.2,0.5,1 and 2 are all common, but the frequently used number is 0.5 is primarily used by industrial users, while 1.0 is mainly utilized by residential households. The accuracy error of electronic electricity meters is closely related to the circuit design capabilities and device performance of energy meter manufacturers, such as using high-precision current and voltage sampling devices to directly improve measurement accuracy. In the early stage of electronic electricity meter calibration process, the accuracy error is complex and environmental requirements are also comparable. During production, it's necessary to control temperature at 24 degrees Celsius. The air conditioning vent cannot face the calibration meter device, and external environmental factors will affect accuracy error. Today's class of electronic technology is less sensitive to the requirements of the calibration environment.

3. Life of electronic electricity meter

As a product, the element of life of an electronic electricity meter is of great concern to users. The general design life of an electronic electricity meter is about 10 years, and it can reach more than 15 years with special requirements. There is no wear of devices without long-term mechanical movement in electronic electricity meter, so the impact on their life mainly depends on the R&D design capabilities and quality of components used by energy meter manufacturers. The main components that affect the lifespan of an electronic electricity meter include LCD displays, electrolytic capacitors, and safety capacitors, among others. For such key devices, energy meter manufacturers will conduct long-term double 85 tests when doing device selection and accelerate the test to verify the life of the device.

4. The anti-interference class of electronic electricity meter

The electronic electricity meter adopts highly integrated chips and components, and is designed with special anti-interference lines or shielding treatment. It has strong anti-interference capabilities. In the electronic electricity meter standards (CE, IEC, MID, CPA), anti-interference has clear project requirements and performance requirements. Only by meeting these requirements can a product be put on the market.
