Product Description

Transformer Characteristic Tester

Darui Electric recommends for you:

The Transformer Characteristic Tester is a fully automated PT and CT characteristic testing instrument,The tests that the instrument can perform include: CT volt-ampere characteristic test, PT volt-ampere characteristic test, CT polarity test, PT polarity test, CT ratio polarity test and PT ratio polarity test, automatic calculation of CT error curve at any point, CT/PT ratio difference and other result parameters.

Instrument Features

1. Single power supply 220AC, safer and more reliable to use (completely abandoning the dangerous 380V live wire);

2. Single unit output 2500V/1000A;

3. Can test transformers with 5A/5A—25000A/5A, 5A/1A—5000A/1A;

4. Only need to set the test voltage and current, the equipment can automatically complete the test quickly, no training required, easy to master;

5. Single unit output capacity is large, full functions, high precision, unique performance;

6. 320×240 large LCD display, full Chinese graphic interface;

7. Uses imported rotary mouse, setting test values is faster and simpler;

8. During testing, the volt-ampere curve can be displayed directly, with clear graphics, intuitive and convenient;

9. Comes with a fast printer, supports on-site printing of test results;

10. Comes with a large-capacity memory, can save 1000 sets of test data, not lost after power failure, can be accessed at any time;

11. USB communication interface, convenient to connect to new laptops, can upload test data for editing, saving or printing;

12. Integrates multiple instrument functions into one, easily achieving multiple uses with one machine, effectively improving work efficiency and reducing labor intensity.

13. Supports offline and online testing
