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

Load Control

Relay for connection/disconnection Phase and Neutral Disconnection on the following conditions:

i)              Over current

ii)             Load Control Limit

iii)     Disconnect signal from Utility Control Centre

Communication function

Optical / RS 485 will be provided for local communication. In addition to this the meter will have a provision for a built in zigbee Module for NAN (Neighborhood Area Network)
