Comprehensive Transformer Characteristic Tester
DARUI Electric recommends
Features
1. This comprehensive transformer characteristic tester is fully functional, capable of testing CT/PT volt-ampere characteristics, transformation ratio and polarity, 10% error curve, phase angle error, and ratio error.
2. Simply set the test voltage, current, and step size, and the device will automatically boost and automatically plot the volt-ampere characteristic curve, eliminating tedious manual voltage adjustment, manual recording, and curve drawing. Fast, simple, and convenient.
3. An external booster can be connected to expand the output voltage range.
4. For volt-ampere characteristic tests, the standalone output voltage is 0-2500V and current is 0-20A; with an external booster, the output voltage is 0-4000V and current is 0-1.5A, enabling volt-ampere characteristic tests for 500kV class 1A transformers.
5. Single-phase 220V power input avoids the danger of using 380V.
6. Large LCD screen displays the volt-ampere curve directly during testing, making it intuitive and convenient. Built-in micro printer for easy printing of test data.
7. Numeric keypad for convenient number input.
8. Equipped with a large-capacity memory that can store 100 sets of test data, which is not lost upon power failure.
9. RS232 communication interface allows connection to a computer for testing, and test data can also be uploaded to a computer for editing and saving.
