Application:
DTZY1122 Three Phase Four Wire Multi-function Electronic Smart Meter brings many enhancements that support emerging needs of smart grid initiatives, such as enhanced memory, greater security, and remote upgrade ability. Developed with technology and communications flexibility in mind, DTZY1122 platform is both a smart metering element that supports RS485, PLCor low-power RF modules. The meter's modular design provides a cost effective solution for many metering applications.
Functions:
Measurement function: Measure forward / reverse active / reactive energy and reactive energy of four quadrants as time period, forward / reverse reactive energy.
Measurement can be set.
Measure maximum demand of forward / reverse active / reactive and maximum reactive demand of four quadrants.
Able to set 10 tariffs, 14 time zones, 12 sets of time period lists, 14 time periods, 13 holidays, holiday and weekend can be preset in different time periods.
Measure each phase and total active power, reactive power, power factor, each phase voltage, current, frequency etc.
Measure total harmonic distortion factor of A, B, C three phase voltage and harmonic rate in 2~31 times.
No-voltage record: Record no voltage of each phase and total no voltage time of four months, record no voltage occurring time, ending time, and the energy in the time of no voltage of the last 10 times.
Record last 10 demand resetting, program, no phase, over voltage, no voltage, unti-phase, over load, current unbalance, calibration time, power off and power on.
Overload monitor: Able to set voice-optical alarm or relay output when load is beyond a certain value.
Energy freeze: Freeze energy by broadcast, also can freeze energy at hour.
Load curve: Select different data group with different or the same time terminal (1 to 1440 mins optinal) to record the data scrolling, record with time remark, and storage spaces is no less than 2 MKB.
Read meter at power failure, you can still read the meter via button or infrared function.
Calculate voltage percent of pass, and separately record the four phase voltage percent of pass of the last four months.
RS485 and infrared communication port.
Active and reactive pulse optical couple output, real time clock pulse optical couple output, two routes programmable relay output.
LCD display.
Three phase power source supply, but even only one phase working, meter still keep running.
Features:
With the DSP technology and real-time high speed calculation, it guarantees the measuring accuracy in case of big load wave and many harmonic waves.
Harmonic analysis function: Measure the harmonic abberration rate of three phase voltage, current and 2ND to 31st harmonic current etc.
Harmonic monitoring function.
Monitor the current and voltage of 2ND to 16th harmonic. When the value is beyond the setting point, meter will alarm and record event.
Each monitoring capacity can be set a limited value separately.
The first 30 times beyond limeted setting event record. The event includes start time, ending time, beyond time, the max value, min value and average value.
Large size data storage is 2MB, which can be extended to 4MB
