In addition, the power meter calculates power factor, realpower, reactive power, and more.The following sections list the metering characteristics of the power meter.Real-Time MeasuringThe following table lists the metering characteristics of the power meter for the real-timemeasurement:Characteristics DescriptionCurrent Per phase, neutral, and average of 3 phasesVoltage L-L, L-N, and average of 3 phases,N-PEFrequency 45...65 HzActive power Total and per phase (signed)Reactive power Total and per phase (signed)Apparent power Total and per phase(signed)Power factor (True)Total and per phase0.000 to 1 (signed) AngleVoltage angle,Current angleCurrent unbalance Per phase, most unbalanced of 3 phasesVoltage unbalance most unbalanced of 3 phasesMinimum/Maximum ValuesWhen any one-second real-time reading reaches its highest or lowest value, the power meter saves the minimum and maximum values in its nonvolatile memory.From the power meter display, you can:? view all min./max. values since the last reset and the reset date and time.? reset min./max. values.All running min./max. values are arithmetic minimum and maximum values. For example, the minimum phase A-N voltage is the lowest value in the range from 0 to 999.9GV that has occurred since last reset of the min./max. values.The power meter provides time stamping for all minimum/maximum values.The following table lists the minimum and maximum values stored in the power meter: Characteristics DescriptionCurrentPer phase and averageVoltage per phase and averageActive power Per phase and totalReactive power Per phase and totalApparent power Per phase and totalDemand ReadingsThe power meter provides the following demand readings. Characteristics DescriptionCurrent Per phase and averageActive, reactive, apparent power Per phase and TotalPeak Demand Values Current Per phase and averageActive, reactive, apparent power Per phase and TotalDemand Calculation MethodsPower demand is the energy accumulated during a specified period divided by the length of the period. Current demand is calculated using arithmetical integration of the current RMS values during a time period, divided by the length of the period. How the power meter performs this calculation depends on the selected method. To be compatible with electric utility billing practices, the power meter provides block interval power/current demand calculations.For block interval demand calculations, you select a block of time (interval) that the power meter uses for the demand calculation and the mode the meter uses to handle he interval. 2 different modes are possible:? Fixed block - Select an interval from 1 to 60 minutes (in 1 minute increments). The power meter calculates and updates the demand at the end of each interval.? Sliding block - Select an interval from 1 to 60 minutes (in 1 minute increments). For demand intervals less than 15 minutes, the value is updated every 15 seconds. For demand intervals of 15 minutes and greater, the demand value is updated every 60 seconds. The power meter displays the demand value for the last completed interval.The following figures illustrate the 2 ways to calculate demand power using the blockmethod. For illustration purposes, the interval is set to 15 minutes.Peak DemandIn nonvolatile memory, the power meter maintains a maximum operating demand value called peak demand. The peak is the highest value (absolute value) for each of these readings since the last reset.You can reset peak demand values from the power meter display. You should reset peak demand after changes to basic power meter setup such as power system configuration.Energy ReadingsThe power meter calculates and stores Per phase and total energy values for active,reactive, and apparent energy.You can view energy values from the display. The resolution of the energy value automatically changes from kWh to MWh to GWh (kVAh to MVARh to GWh).The energy values automatically resets to 0 when it reaches the limit of 999.9GWh,999.9GVAh, or 999.9GVARh. The following table lists the energy readings from the power meter:Characteristics DescriptionEnergy values Active energy0 to 999.9GWhAuto reset to 0 in case of over limitReactive energy0 to 999.9GVARhAuto reset to 0 in case of over limitApparent energy0 to 999.9GVAhAuto reset to 0 in case of over limitPower Quality Analysis ValuesThe power quality analysis values use the following abbreviations:? Fundamental phase current rms: I1? Fundamental phase voltage rms: V1? RMS of up to three harmonics of phase current: Ix, Iy, Iz, x, y, z = 2, 3,…, N? RMS of up to three harmonics of phase voltage: Vx, Vy, Vz, x, y, z = 2, 3,…, N?Total harmonic distortion of the phase current? Total harmonic distortion of the phase voltage? Harmonic distortion of up to three harmonics on the phasecurrent? Harmonic distortion of up to three harmonics on the phasevoltage:THD provides a measure of the total distortion present in a waveform. THD is the ratio of harmonic content to the fundamental and provides a general indication of the quality of a waveform. THD is calculated for both voltage and current.The following table lists the power quality values of the power meter: Characteristics DescriptionTHDTotal,2,3,4,5,,,,,51(51 times) Per phase current (percentage value)X,Y,Z,A,B(5 times each time) Per phase current(rms value)Total,2,3,4,5,,,51(51 times)Per phase voltage(percentage value)X,Y,Z,A,B(5 times each time)Per phase voltage(rms value) Data RecordThe power meter records data to SD card, the following table lists data record of the power meter.Record Record interval1s to 9999s(default 1min)Record formatcsvRecord capacity16GB Memory Store about 2.5K Bytes data each timerecord 12 years (1min interval)Record data"Current Harmonic"fileITHD(%),IHD2(%),IHD3(%),,,,,IHD51(%) (Each phase )"Voltage Harmonic"fileUTHD(%),UHD2(%),UHD3(%),,,,,UHD51(%)(Each phase)"DataSheet" fileVoltage(V);UTHD(%);Current(A);ITHD(%);Frequency(Hz);Power Factor;Current Demand(A);Current Peak Demand(A)&Date;(Each phase and Average) Active Power(W) ;Reactive Power(Var);Apparent Power(Va)Active Energy(Wh);Reactive Energy(Varh);Apparent Energy(Vah)(Each phase and Summary) Total Active Power Deamnd(W) Total Active Power Peak Deamnd(W)&Date Total Reactive Power Deamnd(Var) Total Reactive Power Peak Deamnd(Var)&Date Total Apparent Power Deamnd(Va) Total Apparent Power Peak Deamnd(Va)&Date Other CharacteristicsThe following table lists other characteristics of the power meter:Characteristics DescriptionReset Minimum and maximum values -Peak demand values -Current demand calculation method 1 to 60 minutesPower demand calculation method 1 to 60 minutesEnvironmental conditionsOperating temperature-25oC to +55oCStorage temperature-40oC to +85oCHumidity rating5 to 95% RH at 50oC(non-condensing)Pullution degree2Overvoltage categoryIII,for distribution systems up to 277/480VACDielectric withstandAs per IEC61010-1, Doubled insulated front panel displayAltitude3000m MaxIP degree of protectionIP20 conforming to IEC 60629ColourWhiteContractual warranty12monthsEMCElectrostatic dischargeLevel IV(IEC61000-4-2)Immunity to radiated fieldsLevel III (IEC61000-4-3)Immunity to fast transientsLevel IV (IEC61000-4-4)Immunity to surgeLevel IV (IEC61000-4-5)Conducted immunityLevel III (IEC61000-4-6)Immunity to power frequency magnetic fields0.5mT (IEC61000-4-8)Conducted and radiated emissionsClass B (EN55022 )Standard complianceEN 62052-11,EN61557-12,EN 62053-21,EN 62053-22,EN 62053-23,EN 50470-1,EN 50470-3,EN 61010-1,EN 61010-2,EN 61010-031SpecificationMeasurement accuracyRated current (3 level selectable)600A(0.5% from 6A to 720A) 3000A(0.5% from 10A to 3600A) 6000A(0.5% from 20A to 7200A) Rogwoski coil connect setting600AMRC-363000ANRC-150 or Y-FCT-5106000ANRC-200 or Y-FCT-800CTs connect setting Primary setting: from 1A to 999999ASecondary setting:from 0.001mV to 707mVVoltage0.2% from 5 to 600VPower factor±0.005 Active/Apparent Power IEC62053-22 Class 0.5Reactive powerIEC62053-21 Class 2Frequency0.01% from 45 to 65HzActive energy IEC62053-22 Class 0.5sReactive energyIEC62053-21 Class 2Input-current characteristicsPrimary current range600A 0.5A to 720A3kA 0.5A to 3600A 6kA 0.5A to 7200AMeasurement input range 1/225mV-707mVPermissible overload2V for 10s/hoursPower SupplyPower2*2900mAh PANASONIC lithium batteryWorking time: 10 hoursCharging time: 8 hours5V DC power supply(included adaptor)power consumptionScreen Maximum Brightness2000mWScreen Minimum Brightness1800mWWire diameter for terminalsCurrent inputBNC connector Voltage inputBanana plugDC power supplyDC 5.5*2.1 plug MODBUS-TCP CommunicationTransmission modeRJ45 portCommunication protocolMODBUS TCPSettingsIP addressConfigurable (default 192.168.1.5)Port No.502Port definition Port numberPort namePort functionRemarks1IAA-phase current input Current input2IBB-phase current input 3ICC-phase current input4InN-phase current input5UNN-phase voltage inputVoltage input6UCC-phase voltage input7UBB-phase voltage input8UAA-phase voltage input9UEPE-N voltage input10PowerPOWER 5V DCPower 5-9V DC11USB portDownload log data Plug out(in) USB DISK12RJ45 portMobus-TCP communicationCommunicationAccessoriesAccessoriesVoltage wires5pcs voltage clamp wires with banana plug (2 meters,1.5mm2)Adaptor85-265 AC to 5V DC adaptor(default Europe plug) RemarkRogowski coil not included
