The Function Of The Multi-function Energy Meter

The multi-function energy meter generally has the following functions:

1) Measurement and storage functions. It can measure single and two-way active and reactive energy in various time periods; it can complete the measurement and display of current power, demand, power factor and other parameters. It can store at least the data of the last meter reading cycle.

2) Monitoring function. It can monitor customer power and maximum demand, and prevent electricity theft by analyzing customer power load curve.

3) Control function. Can implement time period control and load control for customers. The former is used for multi-rate time-of-use billing; the latter refers to receiving remote control instructions through the communication interface or controlling the load through the internal programming of the meter (considering the time period and load quota). The electronic energy meter with IC card interface can not only complete the prepayment function, but also have the alarm delay when the purchased electric energy will be exhausted, and the control function of power failure.

4) Management functions. The electronic electric energy meter is connected with the communication network of the power system or the meter reading system through the communication interface to realize remote data exchange with the outside world. The authorized client server in the power network can use the address code of the electric energy meter (usually 12 decimal digits) to accurately complete the time period, time period rate, time period power limit, remaining power alarm limit, representative day, and freezing day. , the setting of demand mode, time and slip, etc.; call and view the real-time power of customers; read the relevant power consumption, and transmit the power metering information to the corresponding department as needed for system scheduling, power control, It is used for power exchange and business billing.
