Active & Reactive Smart Electric Meters Three Phase Four Wires
GPRS for AMR System
Three 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
1. Product's Type—Remote, Remote Carrier, Local, Local Carrier.
2. Electric Power Measurement—Positive/ reverse active power,
positive/reverse apparent power, reactive power in 1,2,3,4 phase
and active/reactive power in A, B, C phase which can be measured.
It can set tagged words of active and reactive group to restructure
the positive/reverse active power and reactive power in 4 phases,
and then for active group, reactive group1 and reactive group 2. It
can storage power data for 12 settlement period.
3. Multi Tariff—It can set for 2 time zones, 2 programs of daily
time and switching time (yy/mm/dd/hh/mm) of these two. Set for
public holidays, date of each and meter number of daily time; Set
for weekly holiday which controlled by its tagged words, and also
set for meter number of daily time for each weekly holiday.
4. Demand Measuring—It can measure max demand and the time when it
occurred for positive/ reverse active power, positive/reverse
apparent power, reactive power in 1,2,3,4 phase, reactive group 1
5. Event Log—With function for logging events such as clear,
program, timing, power down, switch out, switch on, open meter
cover and etc.
6. Electricity Freezing—With multi freezing ways of instantaneous
freezing, timing freezing, day freezing, appoint freezing, on hour
freezing and etc.
7. Load Profile—Support for 6 load data, and the time interval can
be set for any time which from 1 to 60 mins. The time interval for
each load can be the same or not.
8. Measure Function—It can measure voltage, current, phase angle,
apparent power, active power, reactive power, power factor and grid
frequency of total and each A, B, C phase, also it can show the
direction of power.
9. Demand Operating—Handle parameter setting, prepaid electricity
charge, information write back, switch out and switch on demand to
the meter through solidity or virtual medium.
10. State Indicator—LED indicators for pulse, warn, switch out, and
error code would be displayed on LCD, which can help to understand
the working state for meter.
11. Safety Certification—The operations on meter have passed strict
safety certification such as password or ESAM module (SM1), to
promise for the safe transportation of data.
12. Reliable Design—Perfect power source and electromagnetism
compatible design, which are suitable to the strong
electromagnetism disturbance and big occasion of power source
10. Cover for Meter—Fully sealed dustproof and waterproof design,
material of cover has excellent flame retardant and anti-corrosion,
11. Communication Mode—Infrared+RS485 interface, carrier
communication module, wireless GPRS/GSM, CDMA is optional.
