Three-phase Payment-controlled Smart Electricity Meter

Introduction of the product

Three-phase payment-controlled smart electricity meter has a variety of types and configurations, such as carrier or non-carrier; CPU card, RF card or remote; external switch or internal switch, etc. All products have adopted large-scale integrated circuit, digital sampling technology and SMT technology. They have embedded AC voltage and current acquisition module with high speed and precision, which can accomplish high-precision sampling, as well as real-time accurate power measurement; meanwhile they encompass such functions as pre-payment, real-time power billing and real-time monitoring.

Functions

Power Measurement function

It can execute time-measuring of assembled active power, positive and negative active power, assembled reactive power, four-quadrant reactive power, positive and negative apparent power, as well as copper loss and iron loss power.

Multi-rate function

It has adopted two sets of rates and time consumption with capacity of free programming, to support setting special rates comsumption for public holidays.

Step tariff function

It has adopted two sets of step tariff billing, and can set the time of implementing the other billing.

Rates control

It has used local (CPU card / RF card), or remote (carrier / RS485) rates control method.

Freeze function

Support four freezing methods, namely timing freezing, instantaneous freezing, agreed freezing and day-time freezing.

Load curve recording

According to users’ settled time, it will execute cycling record about the content of the selected various data in interval. And the data volume can reach that of 40 days within one-minute interval.

Power network monitoring

Provide monitoring function of exceeding limit. It can set limit value of such parameters as wire (phase) voltage, current, power factors, and can also offer monitoring.

Event recording function

Record various events such as loss of voltage, loss of phase failure, power failing, voltage (current) reverse phase sequence, programming, power demands clearing, broadcasting timing, etc.

Alarm function

It will execute sound and light alarm about such events as loss of voltage, loss of current, reverse phase sequence, overload, reverse power, and battery with less voltage.

Cover-opening recording

It can record whether it has opened the meter cover or the terminal cover.
