TPHGC-A Transformer Characteristics Comprehensive Tester is specially designed by Darelli Electric for testing transformer volt-ampere characteristics, ratio testing, and polarity discrimination. It is a multifunctionaltest instrument. This instrument adopts high-efficiency, low-consumption high-quality materials and specially wound boosters. A microcontroller microprocessor is used for data acquisition, analysis, and storage. It has a built-in micro printer that can print test data and curves. When measuring CT ratio, it can automatically calculate the ratio value. Oneperson can complete all testing work. This transformer comprehensive characteristics tester has the characteristics of light weight and convenient operation.
Functional Features
1. This transformer characteristics comprehensive tester has comprehensive functions and can test CT/PT volt-ampere characteristics, ratio and polarity, 10% error curve, angle difference, and ratio difference.
2. Only need to set the test voltage, current, and step size. The device will automatically boost and automatically draw the volt-ampere characteristic test curve, saving the tedious work of manual voltage adjustment, manual recording, and curve plotting. Fast, simple, and convenient.
3. An external booster can be connected to expand the output voltage range.
4. For volt-ampere characteristic test, the single machine output voltage is 0-2500V, current 0-20A; with external booster, output voltage is 0-4000V, current 0-1.5A, which can perform volt-ampere characteristic tests on 500kV class 1A transformers.
5. 220V single power input avoids the danger of using 380V.
6. Large screen LCD display, directly shows the volt-ampere curve during testing, intuitive and convenient. Built-in micro printer for convenient printing of test data.
7. Digital keyboard for convenient numerical input.
8. With large-capacity memory, can store 100 sets of test data, not lost when power is off.
9. RS232 communication interface, can connect to a computer for testing, and test data can also be uploaded to the computer for editing and saving.
