1. Phase failure alarm of three phase meter: When one of the three-phase power supplies of the meter is powered off, the alarm light will be on. With the help of the remote communication function of the smart electric meter, the user can remotely control various smart loads at home, such as air conditioners, washing machines, refrigerators, lighting, etc., through the Internet or mobile communication network, and at the same time through the remote communication function of the smart meter It can also realize remote monitoring and alarm. The user needs to check the line to find out the reason.

2. Voltage and current imbalance alarm: When the three-phase voltage and current of the meter are unbalanced, the alarm light will flash. If the fluctuation is not large, you can ignore it. If the fluctuation is large, check the wiring and electrical equipment.

3. Overload alarm: When the user's electricity load is too large, exceeding the load of the meter, the alarm light will be on. The user should reduce the electrical load or connect a transformer.

4. Overvoltage alarm: If the voltage is greater than 1.15 times the rated voltage of the meter, the alarm light will be on. The user needs to check the reason for the excessive voltage, when the voltage is reduced to within 1.15 times.

5. Power reverse alarm: When the connection of the electric meter is reversed, the alarm light of the electric meter will be on, and the user of 3 phase electricity meter needs to correct the connection.
