What do the parameters of the home smart meter interface represent?

Nowadays, smart meters have entered thousands of households, but do you know what these numbers and flashing lights on prepaid smart meters represent?

There are two seals on the top of the smart meter, the left side is the "strong inspection seal", and the metrology verification center will mark the seal information after the test is qualified. On the right side is the "manufacturer seal", and the manufacturer will be marked with the manufacturer's seal information after passing the first school, the second inspection and random inspection.

It is rumored on the Internet that the power supply company will disassemble the smart meter and deliberately adjust the meter faster, and from these two anti-counterfeiting seals, it can be known that the power supply company cannot open the meter at all, and the rumor is self-defeating. It must be noted that according to the Electricity Law of the People's Republic of China, it is illegal to deliberately speed up the meter. The power supply company is a state-owned enterprise, and it will strictly abide by national laws and regulations.

Below is the LCD screen, the screen will display the cumulative power, time, peak and valley power, most of the electricity information collected by the smart meter can be viewed through the white button on the right side of the nameplate below.

Smart meter surface related parameters:

1. Pulse light: When we are observing the smart meter, the most conspicuous thing is the flashing red light, which is the pulse light, which is similar to the turntable of the old meter. The pulse light flashes, which means that the line is under load, that is, there is an electric current passing through the home. The faster the flash, the more power is used.

So why is there no electricity at home, and the red light is flashing?That's because smart meters are much more sensitive than previous mechanical or electronic meters, accurately calculating the amount of standby energy consumption, and the pulsed lights will flicker continuously. Therefore, pulling out the plug in time after using the electrical appliances can not only reduce the waste of electrical energy caused by standby energy consumption, but also avoid property damage caused by accidental short circuit.

A is the reference current and 60A is the maximum current allowed to pass through. Currents between 5 and 60A are allowed for smart meters.

V 50Hz: single-phase rated voltage 220 volts, rated frequency of AC 50 Hz, is the rated voltage and frequency specified by the state.

imp kwh: The user consumes 1 kWh of electricity, and the pulse light flashes 1200 times. Some meters say 1600imp kwh, that is, for every 1 kilowatt-hour of electricity consumed, the pulse light flashes 1600 times. Although the meters used are different, the metering principle and accuracy are the same.

5. RXD and TXD small lights are information and communication indicators: RXD is the received data, and TXD is the sent data. The transmission signal is only a signal, and it has nothing to do with metering.

6. Trip indicator: The trip indicator is in a "dormant" state for a long time when using electricity normally, and the indicator light will light up when the bill is in arrears, and it will automatically turn off after the payment is restored. PS: Now most smart meters will be automatically restored after the power outage after the arrears are paid off, and you do not need to operate manually, and non-smart meters still need to be manually restored.

7. Infrared area: The infrared area will only light up when the meter is read, and the meter reader needs to be used to align the infrared area for meter reading

8. Meter number: next to the bottom ***, this number is unique, and this number can be seen on the electricity invoice given to you by the power supply bureau when you pay the bill.
