Variable Frequency Transformer Comprehensive Characteristic Tester

RDHG-E Variable Frequency Transformer Comprehensive Tester is a new generation of innovative CT and PT testing instrument developed on the basis of traditional transformer volt ampere characteristic ratio polarity comprehensive tester based on voltage regulator, voltage booster and current booster, widely listening to users' opinions, after a lot of market research and in-depth theoretical research. The device adopts high-performance DSP and FPGA, advanced manufacturing technology, which ensures stable and reliable product performance, complete functions, high degree of automation, high test efficiency. It is a professional test instrument for mutual inductors in the power industry.

1. Full-featured, not only satisfy the test requirements of various CTs (include TP class), such as the excitation characteristics (i.e., volt-ampere characteristics), ratio, polarity, secondary winding resistance, secondary burden, ratio error and phase displacement, but can also be used for the tests of various PTs, including excitation characteristics of the electromagnetic unit, ratio, polarity, secondary winding resistance, ratio error and phase displacement.

2. Automatically give CT, VT parameters, including knee point voltage / current, 10% error curve, the accuracy limit factor (ALF), instrument security factor (FS), the second time constant (Ts), remanence coefficient (Kr), saturated and unsaturated inductance etc.

3. Based on advanced principle of low-frequency test method that can meet the CT test on knee voltage up to 30kV.

4. The test meets various transformer standards such as IEC60044-1) and  IECC60044-6, and automatically selects which standard to test according to the transformer type and level.

5. Friendly and beautiful interface, graphical LCD display

6. The Variable Frequency Transformer Comprehensive Tester can store 1000 groups of test data that won’t be lost when power off. After test ended, the data can be coped to PC by USB disk for analysis and being transformed into WORD report.

7. Test is simple and convenient, one-click can complete tests of CT secondary resistance, excitation, ratio and polarity.

8. The panel is equipped with a printer, which can print the generated test report.

9. Light weight, easy to carry.
