Main Functions:
1. Measuring function of power energy:
1.1 Measuring positive and energy,reactive energy in four quadrants(with four tariffs)and total power energy.
1.2 Four impulse output ports,width and contene can be programmed set solely or meantime as:positive active energy,negative energy,reactive energy in one quadrants,reactive energy in two quadrants,reactive energy in three quadrants,reactive energy in four quadrants.
2. Function of demand display:
Recording positive and negative active energy,reactive energy in four quadrants(four tariffs demand),total 30 demand data,and recording the time about every demand data,the fashion of count is interzone or glide.It retains the periodic averaga power every time in counting demand and can be displayed or recorded through function of load curve.
3. Voltage,current,power factor and function of power display:
3.1 Voltage,current,power factor of each phase and total power factor can be recorded and displayed.
3.2 Active instantaneous power(ABC total)and reactive insttantaneous power(ABC total )per second can be recorded.
4.Each time segment control:
4.1 It provides two time segments:weekend interval.
4.2 It provides four sets of interval tables and four fixed rate programmes. Each interval table can be divided into ten intervals per day.
4.3 Up to ten intervals can be programmed.to be chose corresponding interval table controlling the conversion of interval
5 Auto meter-reading
5.1 It provides the function of auto meter-reading to set up "Day"and "Hour",to finish power memory and demand reset.
5.2 The perlod of auto meter reading may be "Mouth:or"Week",Up to eight times",meter-reading can be set up automatically every period.
5.3 Power memory and demand reset can be operated solely through auto meter-reading.
6. Reset(Power memory and demand reset):
Four ways to finish power memory and demand reset):manually.
automatically ,through RS485 and infrared port.They may be forbidden solely or exist meantime.
7.Function of load curve:
It provides the recording function roll data according to setting up time distance to select matter.You can set up 7 kinds of data sampling intervals:1.5,10,15,20,30,60 minutes.sampling can be selected as:positive and negative active total energy in four quadrants,voltage(ABC),current(ABC),power factory(ABC total),frequency(Hz),demand periodic average power of active and reactive,active instantaneous power (ABC total),reactive instantaneous power(ABC total).Six groups of data can adopt same or different time distance.
8. Function of energy freeze:
It can freeze positive or negative of every tariff energy and total energy,current reactive in two quadrands of every tariff energy and total energy through RS485.
9. Record the time of power failure works:
It can record 64 times of power failure works recording power failure work and start work"month,day ,hour,minute,"for analysis and inspection.This data can prevent from appearing man-made failure and can add metric security.
10. Record the phase lost and time:
1. It can record the times,positive and negative active energy of the phase lost for each phase,further recording the above data of one phase lost or two phase lost together.
2. It can record the start-end times(month,day,hour,minute)of the phase lost for nearest 8mtimes and the total positive and negative active energy of the start and end time for each phase lost.
11.Data display:The content and the time display can be set by programme.
12. Input and output interface:
Four lines impulse output interface with optical isolation data transport interface,which can supply the power with outside of the interface.
