It is a specialized instrument for testing current transformers: during the test, only the test voltage/current value needs to be set, and the device can automatically boost voltage/current, quickly displaying the transformer's volt-ampere characteristic curve or transformation ratio, polarity, and other test results. It supports data storage and on-site printing, not only saving tedious labor such as manual voltage adjustment, manual recording, and curve plotting, but also allowing test data to be uploaded to a computer via USB interface for editing, saving, or printing. It is simple and convenient to operate, improving work efficiency, and is 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, among others.

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 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 test requirements, posing significant safety hazards and easily causing electric shock or even casualties.

2. Compliant with national maintenance regulations:

The equipment's power output is all real voltage and current values, with waveforms being standard sine waves at 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, making it very suitable for on-site maintenance use.

4. Full functionality:

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

5. Simple wiring method:

It uses a single power input port; only 6 test ports are needed to complete all CT test items. The wiring method is safe and simple, 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 to new laptops.
