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 cost-effective high-tech product. It is a multifunctional on-site test instrument designed for volt-ampere characteristics, transformation ratio, polarity, error curves, calculation of knee point, and secondary side loop inspection, etc.

Safe and reliable

It adopts the domestically pioneering MBC power control technology, with single-phase AC220V input power, 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 the test requirements, which poses significant safety hazards and can easily cause electric shock or even casualties.

2. Compliant with national maintenance regulations:

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

3. Large output capacity:

When the single unit is powered by 220V, 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. Complete functions:

It can test CT's 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, with safe and simple wiring, very suitable for on-site use, effectively reducing labor intensity and improving work efficiency;

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

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

8. USB interface: Convenient for connecting to new laptops.
