Product Description TD3250 Portable Three-Phase Energy Meter Tester 1. SummaryTD3250 is a portable standard meter specially used for electric energy meter on-site detection, AC sampling etc. It integrates the functions of electrical parameter measurement, electric energy meter calibration, connection mode identification, harmonic analysis, waveform display, phasor diagram display, data management. 2. FeaturesAccuracy: Class 0.02 or 0.05.3PH voltage measurement: 0~480 V.3PH current measurement (direct) : 50 mA~ 12 A.3PH current measurement (clamp) : 100 mA~ 120 A.Support electric energy pulse optical/electrical pulse input.LCD touch screen.Support AC 100 V~264 V wide range supply.Support large capacity lithium battery.Internal memory, and quickly record test data.USB and RS232 interfaces.3. Application ☆ Calibration for Energy Meter Online Support direct measurement for 10 V~480 V, 0.05 A~12 A, and current clamp measurement for 0.1 A~120 A; electric energy metering;Application 1 (direct measurement of current): applicable to the calibration of single-phase / three-phase voltage source, current source, power source, etc. in the laboratory or on site.Application 2 (use clamp for current): It is not necessary to cut off the circuit, just clamp the current line into the jaw, and you can real-time measuring online. ☆ CT Transformation Ratio Calibration CT transformation ratio test: use large current clamp for primary signal of CT, and with small current clamp for secondary signal of CT; Calculate the transformation ratio of CT and the phase relationship of primary/secondary current. Help judge if the CT runs well.Note: Standard configuration for 5 A clamp, which can be used for the secondary side, If user need other clamps should indicate the optional specification in the order. 4. Characteristics☆ Convenient Operation Color LCD screen, supporting touch operation.Front panel wiring: convenient for the user to replace the test lead.220 V mains power supply or the lithium battery mode available.Internal memory and quickly record the test data, data can be transferred to the PC. The volume is equivalent to the conventional tool box, weighs about 8 kg. ☆ Connection Mode Identify and Graphical Display S/NFunction declaration1Accurately measure/display the amplitude and phase of voltage and current of each phase.2Accurately measure the phase between voltage and current of each phase, and visually display them in the form of phasor diagram.3Automatically identify the actual results of voltage and current, including phase sequence display.4The trend chart display function of the measuring channel can display the trend change of the measured electricity quantity with time.5Users can customize single or multiple power waveforms for display.☆ Harmonic Function S/NFunction1It can measure 2nd ~63rd harmonics and display the amplitude or content.2Display the phase value of each harmonic.3Display the waveform after harmonic superposition.4Display the phase of each harmonic. The spectrum of each harmonic is displayed visually in the form of histogram (fundamental wave is 100%). ☆ Data ManagementThe equipment can store and manage the test data on site.The selected data can be saved to the mobile USB flash disk. ☆ Test SoftwareUSB and LAN communication interfaces, and customize the test report.5.
