Four Wire Three Phase Prepaid Energy Meter With Plastic Cover IEC61036 Standard

Plastic Cover 3 Phase Prepaid Electricity Meters Three Phase Four Wire Prepayment meter 

Working principles

The Three Phase Prepaid Energy Meter collects voltage signals from the potentiometer. The current signals collected from the shunt to get multiplying signals through multiplication device, and after frequency converting, get counting pulses, Three Phase Prepaid Energy Meter is in direct ratio with the product of voltage and current.The counting pulses of electric energy will be sent to CPU for processing through electro-coupling, and be stored in nonvolatile EEPROM after operation. These pulses and information from IC card that been stored with some volume of electricity and data of supervisory demands will be processed by micro processing system in the meter then provide signals of display, warning and cutting-off state etc.
