It is able to measure the no-load current, no-load loss, short circuit voltage, short circuit (loading) loss of transformer and to conduct harmonic test and analyze to the 31^st harmonics.

1. Able to measure the no-load current, no-load loss, short circuit voltage, short circuit (loading) loss of transformer.

2. Able to conduct harmonic test and analyze to the 31^st harmonics.

3. The instrument can make range changing automatically, allow to measure the width of voltage and current range, and can also simplify wiring.

4. For no-load and load test of three-phase transformer, the instrument can automatically determine whether the instrument is wired correctly, and display vector diagram of three-phase voltage and current.

5. One machine can finish the load test of distribution transformer with less than 1,000kVA under full current; it can also complete the load test of distribution transformer with less than 3,150kVA under one third of the rated current (under one third of the rated current, the instrument can calculate the load loss parameter under rated current).

6. All the test results are automatically calibrated. The instrument can automatically do the following: Waveform calibration, temperature calibration, calibration of non-rated voltage, calibration of non-rated current and many other calibrations, to obtain higher testing precision.

7. 320×240 large screen, high-brightness LCD display, pure-Chinese menu and operation hints realize the friendly man-machine interaction of the instrument. Touch keys make operation easier, and wide-temperature-range LCD with brightness control makes it able to be used in all the seasons.

8. Users can preset 40 sets of parameters of tested objects in the instrument, and these parameters can be deleted and added to at any time as demanded, which makes it quite convenient to use.

9. It is equipped with real-time electronic clock to automatically record test data and time to save and manage test results.

10. Panel-type thermal printer can rapidly print test results on site.

11. It has functions of power failure storage and browsing of data (tested object setting, measurement result, test time, etc.), and can save 500 sets of test result data and be connected to computer for data transmission.

12. It can be externally connected to voltage transformer and current transformer to expand measurement range, and can measure tested object with any parameter.
