Darui Electric recommends for you:
The instrument transformer volt-ampere characteristic tester is a fully automated (indirect sampling) PT and CT characteristic testing instrument.The tests that the instrument can complete include: CT volt-ampere characteristic test (1A, 5A), PT volt-ampere characteristic test, CT polarity test, PT polarity test, CT dynamic stability and short-time thermal current, CT ratio and polarity test, PT ratio and polarity test, automatic calculation of error curves at any point for CT, and CT/PT ratio error and other result parameters.
Overview
Instrument transformer volt-ampere characteristic comprehensive tester, referred to as instrument transformer volt-ampere characteristic tester.
1. The instrument is safe and convenient to operate. It is a fully computerized device with a built-in imported high-performance CPU and 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. It features an independent integrated AC 220V power supply design, eliminating the need for external current-boosting or voltage-boosting equipment and 380V power supply.
2. Large output capacity (10~20KVA). The maximum output voltage for volt-ampere characteristic tests is up to 1000V at 20A, and the maximum current for ratio tests is up to 600A at 20V. The instrument's output capacity is 10KVA.
3. Power compensation technology is adopted, so sampling values do not require software correction.
4. 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 at 3A, the external current booster can increase the current up to 1000A, and the external voltage regulator can output up to 1500V at 20A. When using the external voltage booster, volt-ampere characteristic tests can be performed on current transformers of up to 500KV class at 1A.
5. 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, beautiful, and easy to analyze. It comes with a built-in micro printer that can print curves and test results at any time.
6. The instrument uses a rotary mouse as the input device, which is convenient and simple to operate and has a long service life.
7. The instrument has a built-in Flash memory. Data is saved and will not be lost after power failure. After on-site tests are completed, test results can be viewed and printed indoors.
8. 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 documents for editing.
9. The instrument power supply supports adaptive AC220V and AC380V input.
