model td3810, a high-precision three-phase standard, can simultaneously measure multiple electrical parameters in an ac circuit by three-phase y/v and other wiring modes, such as voltage, current, frequency, phase, harmonic, active power/electric energy, reactive power/electric energy, apparent power, power factor, etc.

meanwhile, model td3810 is a field detector for three-phase ac electric energy meters. the optional accuracy classes of power and electric energy are 0.01 and 0.02.

applied to calibrate ac standard source, and can be used as a standard for electric energy metering.

applications (class 0.01)

● calibrate single-phase or three -phase ac voltage or ac current standard sources (class 0.02 and below) 

● calibrate single-phase standard electric energy meters (class 0.02 and below)

● field calibration of single-phase or three -phase electric energy meter calibrators (class 0.02 and below)


● electrical parameter measurement: ac voltage is from 6 v to 528 v, ac current is from   1 ma to 120 a, automatic or manual switching on all ranges.

● waveform display: oscilloscope function can display the waveform of the measured electrical parameters in real time.

● harmonic analysis: measure 2nd to 64th harmonic, analyze harmonic content and total harmonic distortion, and draw harmonic histogram.

● phase measurement: measure phase difference between the three-phase electrical parameters by synchronous sampling, and intuitively display by phasor diagram.

● electrical energy metering: standard energy pulse i/o function can be used as a standard for three-phase ac electrical energy metering.

● magnetic field measurement: measure the magnetic induction or other weak ac magnetic field at the measured meter position of the electric energy meter calibrators.

● meter potential difference measurement: measure the meter potential difference of the calibrators for ac electrical energy meters.

● clock measurement: a built-in pps standard second pulse i/o function can calibrate time for the measured devices with the ability to sustain voltage of 380 v.

● other function: temperature and humidity measurement, stability test, trend curve display, data statistics and analysis, data linear calculation, power constant measurement, etc.


● current input just with a pair of terminals. no shifting on the primary side of the transformers, it will not cause damage or change the measurement accuracy no matter which range suddenly enters a large current.

● high reliability, the switch will not damage the instrument in a limit state (e.g. 500 v, 100a), but can also ensure the value accurate.

● minimize signal conversion, adc and other circuit drifts by self-calibration function to ensure values accurate for a long-term. the self-calibration function is still effective even with 100 a dc current in the loop.

● the temperature coefficient of voltage or current is less than 0.5 ppm/k, the 1 year change rate of major specifications is less than 50 ppm, and the average trouble-free running time of the instrument is more than 10,000 hours.

● good electrical isolation and protection between ac voltage and ac current measurement loop.

● large lcd touch screen, more intuitive of value display and easier operation.

● easy to set up automatic detection system via the built-in rs-232 interface.

● the proprietary software that meets the requirements of jjg 597-2005, supports on-site to analyze errors, record data and print reports for the measured devices.

● strong adaptability and expandability to meet the needs of upgrading the technical standards of electric energy meters.
