Single Phase Fee Control Smart Electric Meter is a smart metering device with special design for nation smart grid. With independent infrared, RS485, carrier communication and IC card interface, it can support for remote or local fee control function. The meter has advantages of high accuracy, good linearity, wide range and long life, which can widely used in city, country or school and any enterprise.
Main Functions
Measuring function:
Meter have two measuring elements - one in phase and other in neutral path. Meter can measure import & export active energy, import & export reactive energy. The measurement type can be set.
Display function
Meter have two status: Cycle display status and button press display. When pressing the button, User can set according their request. Button press will Backlight the LCD. Display cycle can be set within 5~20 seconds, The default is 5 seconds.
Electricity parameters measurement and monitoring
Measure record and display voltage, current, power and power factors. Error is not more than ± 1%. Provide out of limit monitoring capability, Voltage, Current, Power factor can be setup the limit value and monitoring.
Load Profile function
60 days data to be recorded with 15 minutes integration period for kWH, kVArH (lag) kVArH (lead), Average Voltage, Average Current, Power Factor, Frequency.
Time of Use function
Support 8 tariff registers / 12 time zones per day can be remotely programmable (OTA) for the changing values, currency etc.
Tamper/Event recording function
A total of last 50 events considering all tampers defined must be detected and logged as tamper events on first in first out basis along with date & time of occurrence and restoration, total tamper counts with tamper identification. Snapshot of kWh, V and I shall be recorded along with the following tamper events.
Cover open detection – First instance
Phase and neutral are interchanged
Neutral disturbance
Magnetic Interference
Missing Potential
Alarm function
Alarm for power on/off, Under Voltage, Over Voltage, Over Current, Mal functioning of relay
