It is a specialized instrument for testing current transformers: during the test, only need to set the test voltage/current value, the device can automatically boost voltage/current, and quickly display the volt-ampere characteristic curve or transformation ratio, polarity and other test results of the transformer, supporting data storage and on-site printing, which not only saves tedious labor such as manual voltage adjustment, manual recording, and curve drawing, but also can upload test data to a computer via USB interface for editing, saving, or printing. It is easy to operate and improves work efficiency, making it a high-cost-performance high-tech product. It is a multifunctional on-site test instrument designed for volt-ampere characteristics, transformation ratio, polarity, error curves, calculation of inflection points, and secondary side loop inspection, etc.

Safe and reliable

Domestically pioneering MBC power control technology, single-phase AC220V input power supply, and the working power and power supply share one input port, making the design more scientific and reasonable, and the use safer and more reliable.

Note: Other similar products have separate input methods for working power and power supply, and also require three-phase AC380V dual live wire input to meet experimental requirements, which poses significant safety hazards and can easily cause electric shock or even casualties.

2. Compliant with national maintenance regulations:

The equipment's power output is all real voltage and current values, and the waveform is a standard sine wave with a frequency of 50-60Hz; it can effectively simulate the real state of transformers, complying with relevant national maintenance regulations.

3. Large output capacity:

With single unit 220V input, the maximum voltage output is 0-1000V, and the maximum current output is 0-600A, which is very suitable for on-site maintenance use.

4. Complete functions:

It can test CT volt-ampere characteristics, transformation ratio, polarity, 5% and 10% error curves, CT primary current flow, and CT demagnetization, etc., easily achieving multiple uses with one machine.

5. Simple wiring method:

It adopts a single power input port; only 6 test ports are needed to complete all CT test items, with safe and simple wiring, very suitable for on-site use, effectively reducing labor intensity and improving work efficiency;

6. Quick printing: Uses a thermal printer, automatically filters and prints typical report data, very suitable for on-site data comparison.

7. Large capacity FLASH storage: Can save 1000 sets of test data, and data can be retained for 10 years after power failure.

8. USB interface: Convenient for connecting new laptops.
