3. Function Introduction
3.1. TOU energy measurement (six tariffs, 4 quadrants)
Measure total and the energy by 6 tariffs for import/export kWh, kvarh as well as the kvarh of 4 quadrants, the defination of 4 quadrants is described in diagram 3.

Diagram 3: Defination of 4 Quadrants
There are two types of reactive measurement mode as following:
1) Import Reactive= Ⅰ Quadrant + Ⅱ Quadrant
Export Reactive= Ⅲ Quadrant + Ⅳ Quadrant
2) Import Reactive= Ⅰ Quadrant + ⅣQuadrant
Export Reactive= Ⅲ Quadrant + Ⅱ Quadrant
These two types of measurement mode can be programed before usage.
The accuracy calss for reactive measurement is 0.2S and calss 1.0 for reactive, the reactive accuracy is inspected by follow the standard 《Class 1 and 2 Static AC Active Energy Meter 》
Year section (Maximum 14 times): The one year can be devided into several time section which can be applied with different schedule (Maximum 12 times) of day switch times (Maximum 14 times), the tariff for each day switch can be programmed but the maximum number is 6 tariffs. There are special time in a year which can be programmed like the weekend and holiday, customer may set special day switch schedule for these days. Current tariff can be displayed and reviewed on the left buttom of LCD.
3.2. Measure current, voltage, frequency and power
Meter can measure voltage & current of each phase and each element, measure total and reach pahse & element kW, kvar, power factor and frequency. The voltage between the virtual center and line for a 3 phase 3 wire meter can be calculated. The distinguish ability for voltage 0.01V, for current is 0.001A, for kW and kvar is 0.0001, for frequency is 0.001Hz. The power direction can be indicated by displying the symble “P”, “+”, “-”, “Q” and “1~4”.
3.3. Calculate M.D
Meter can measure total M.D. of import/export kW & kvar, 4 quadrant kvar with time, and the M.D. can be measured by each tariffs also. The demand interval is programable from 5, 10, 15, 30 and 60 minutes, sliding time is programable from 1, 2, 3 and 5 minutes.
3.4. Harmonic analyze
DSP convert the voltage and current signal by FFT in 256 points, then the value, phase of 2~39 times harmonic voltage and current can be calculated out, the accuracy for harmonic value is 2% (for 2~21 times harmonic), the phase accuracy is +1~2 degree. All harmonic information can be displayed on LCD, and the harmonic data storage can be read out through communication port. There are 6 kinds of harmonic date will be stored like: n times harmonic voltage, orginal phase and the harmonic value, n times harmonic current, orginal phase and the harmonic value, total aberrance rate of harmonic voltage, total aberrance rate of harmonic current. The harmonic value can be display on LCD in histogram format.
3.5. The record of 12 months account data
Meter can record total and TOU kWh, kvarh, M.D. and M.D time of current month and last 1th to 12th month. The billing time is clock 00:00 from the frist day for each month, and this billing date can be programmed.
3.6. The record of load curve
The record mode of load curve can be set through any communication port on meter, there are 8 kinds of data can be record, user may use this date to draw curve for analyse.

The memory size of load curve data storage is 4M bytes. The minimum record interval for these data is 1 minute. The data items to be record and the interval areprogrammable. Meter will start to record each data according to the setting from the pre-set ‘start time’
Calculate formula: T =
T = the record of curve of load time length
M = FLASH memory (-9D meter memory is 4M)
L= Index table length (-9D meter memory is 16.5bytes)
Li= Total bytes of the i class data
Ti= the setting time interval of i class data
3.7. Main and Subsidiary Tariff Setting
There are two tariff settings can be programmed in the meter, current active tariff is main tariff and the subsidiary tariff is backup tariff. The switch time for these two settings can be programmed. And there are different symbles on LCD to indicate the main and subsidiary tariff, ① for main and ② for subsidiary. When meter is running under season tariff, the two symbols will not displayed.
3.8. The record of event
3.8.1. Outage
Meter can record last 10 times of outage time, starting time, times andaccumulative total outage time.
3.8.2. Loss Phase
When the power is on at 3 phases 4 wires mode, if the voltage of 1 phase is lower than ug and the casting time is longer than tu, and the current of the phase is lower than 0.5%IB±0.05%IB,the phase is Power down; When the voltage of Loss-phase goes higher to ug and casting longer than td, the phase resumes. In 3P3W mode, if the total voltage of element A & C lower than 1.2 times of Un, B phase lose phase. If the voltage of element A&C ua－uc|≥u0, and casting longer than tu, and the current of the element lower than 0.5%Ib±0.05%Ib, A phase lose phase. When |ua－uc| is lower than u0, and the casting time longer than td, the phase resume. When loss phase is taking place, happening time, loss phase times and total time will be recorded. Event light will be turned on automatically. After loss phase, ending time will be recorded and alarm will be cancelled.
ug: Limited Value for loss phase, can be set up(25V~Un，Un=57V or 100V), default 30V.
tu: Loss phase casting time, can be set up(1 min~99 min), default 1 minute.
td: Loss phase resume casting time, can be set up(1 min~99 min),default 1 minute.
3.8.3. Loss voltage
If the voltage of a loss voltage is lower than 78％Un±2V, the current is higher than 0.5%Ib+0.05%Ib, and cast longer than te, this phase loss voltage. Loss voltage start/end time, meantime power and total time will be recorded, event light turn on. But, when 3P3W, if voltage of element A&C is lower than Uw, it is not loss voltage.
When voltage of the phase resumes to 85%Un±2V, and cast longer than tf，timing stops, Loss voltage stops. The meter will record the ending time, meantime power and cancel the alarm.
The meter has the function to record all loss voltage events from first time to 10th time, loss voltage times and total times. Besides, the meter recorded the active energy of import/export, metering from the communication port.
Un：Limited value for loss voltage, can be set up(20V~Un，Un=57V or 100V)，default 57V;
Uw：the up limit of voltage failure in three phase three wire system can be set to 20V~Un，Un=57V or 100V, the default setting is 57V；
te Loss voltage casting time, can be set up(1 min~99 min),default 1 minute;
tf Loss voltage resuming time, can be set up( 1 min~99 min), default 1 minute.
3.8.4. No load
In 3P3W mode, when each current is lower than I0，either the voltage of A or C is lower than I0，it is unload. The Event light turn on, meter records start/end time and total time.
I0: Limited value for unload, can be set up(20mA~99mA)，default 30mA.
3.8.5. Loss current
When loading, if the current of a phase Is lower than Ig，and lower than 1/Riof the average of the voltage for another 2 phases, and cast longer
