What are the advantages of smart meters

The main types of smart meters are IC card meters. The user holds the IC card to the power supply department to pay for electricity purchase. The power supply department uses the electricity sales management machine to write the purchased electricity into the IC card. The user holds the IC card and swipes the contactless IC in the induction area. Card (referred to as swiping card, the same below), you can turn on the power supply, and remove the card after power supply. When the remaining power in the meter is equal to the alarm power, the power off alarm (or buzzer alarm) will be triggered. At this time, the user can swipe the card in the induction area to restore the power supply; when the remaining power is zero, the power will be automatically switched off, and the user must The electricity can be restored only when the card is used to pay for electricity again. For residential electricity, when compared with mechanical meters and electronic meters, it has the following advantages:

1. It has a variety of anti-tamper functions, small starting current, no creep, wide load, low power consumption, flat error profile, and good stability during long-term operation. Single-phase local charge-controlled smart meter
2. Beautiful appearance, small size, light weight and easy installation.
3. High accuracy: fully electronic design, built-in imported special chip, the accuracy is not affected by frequency, temperature, voltage, and higher harmonics.
4. Long life: using SMT technology, optimized circuit design, no need to adjust the circuit after the whole machine leaves the factory.
5. Low power consumption: The low power consumption design is adopted to reduce the line loss of the power grid.
6. Pre-purchased electricity; IC card transmits data to realize data readback, including: readback of total electricity, remaining electricity, accumulated electricity purchased in the meter, total electricity purchases and other information.
7. Store table constants, initial values, user addresses, names and other information.
8. Overload alarm power off, residual power alarm, remind users to purchase electricity in time.
The emergence of smart meters has also brought many benefits to the energy meter testing institutions. For example, in the past, when testing a mechanical or electronic watch, after installing the meter on the energy meter detection device, the debugger needed to manually input the address of each meter in the debugging software, as well as the active and reactive power levels of the meter, and the application of the meter. These have greatly increased the workload of the debugging personnel, delayed the delivery time of the electric energy meter, and caused a non-negligible impact on the brand image of the enterprise. However, since the birth of the smart electric meter, the debugging personnel only need to put the meter on the meter. Then connect the network cable port of the debugging computer to the network port on the energy meter verification device, and set up the communication serial port between the PC and the device, and then various parameters can be automatically generated on the verification software. During the process, whether the quality of the smart meter meets the national standard can be seen at a glance on the computer display.
