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 saving 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 provides real voltage and current values, with standard sine wave waveforms at a frequency of 50-60Hz; it can effectively simulate the real state of transformers and comply 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, etc., easily achieving multiple functions in one unit.
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: It uses a thermal printer, automatically filters and prints typical report data, making it 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 retained for 10 years after power failure.
8. USB interface: Convenient for connecting to modern laptops.
