Features of the Comprehensive Tester for Transformer Volt-Ampere Characteristics, Ratio, and Polarity:

1. The instrument is safe and convenient to operate. It is a fully computerized device with a built-in imported high-performance CPU, ensuring high reliability. After setting the test values according to the interface prompts, there is no need for manual contact with the tested equipment. The instrument automatically completes the test, keeping test personnel away from high-voltage circuits and ensuring their personal safety.

2. Large output capacity: The maximum output voltage for volt-ampere characteristic tests is up to 1000V, and the maximum current for ratio tests is up to 600A. The instrument's output capacity is 5KVA.

3. Optional accessories include an external voltage booster, external current booster, and external voltage regulator. The external voltage booster can increase the voltage up to 2000V, 3A; the external current booster can increase the current up to 1000A; the external voltage regulator can output up to 1500V, 20A. When using the external voltage booster, volt-ampere characteristic tests can be performed on current transformers up to 500KV class, 1A.

4. Large 320*240 dot-matrix Chinese character graphical interface. After the test is completed, the volt-ampere characteristic curve can be displayed directly. The graphics are clear and aesthetically pleasing, making analysis easy. It comes with a built-in micro printer that can print curves and test results at any time.

5. The instrument uses a rotary mouse as the input device, making operation convenient and simple, with a long service life.

6. The instrument has a built-in Flash memory. Data is not lost after power-off. After on-site tests, test results can be viewed and printed indoors.

7. The instrument is equipped with an RS232 communication interface, which can be connected to a computer via a serial cable to achieve communication between the PC and the instrument. Test personnel can use the computer to control the instrument for testing or upload test data from the instrument. The PC application software provided with the instrument is powerful, aesthetically pleasing, and easy to operate. It can save and print test results and export test data to EXCEL format for editing.

8. The instrument's power supply supports adaptive AC220V and AC380V power supply.
