Functions Of Multifunctional Watt Hour Meter

The multi-functional watt hour meter generally has the following functions:

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

2) Monitoring function. It can monitor the customer's power and maximum demand, and prevent the customer from stealing electricity by analyzing the customer's power load curve.

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

4) Management functions. The electronic watt hour meter is connected with the communication network or meter reading system of the power system through the communication interface to realize the remote data exchange with the outside world. The client server with authority in power network uses the address coding of electric energy meter (generally 12 decimal digits), which can accurately set the time period, time period rate, time period power limit, residual power alarm limit, representative day, freezing day, demand mode, time and slip; call and view the customer's real-time power; read the relevant power consumption, and transmit the power metering information to the corresponding department as needed for the system Dispatching, electric energy control, electric energy exchange and business billing.
