1. The first in China to adopt MBC power control technology, with 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 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 and comply with relevant national maintenance regulations.
3. Large output capacity:
With single-unit 220V input, the maximum voltage output is 0-2500V, and the maximum current output is 0-400A.
4. Full functionality:
It can test the steady-state/transient characteristics of CT: volt-ampere characteristics, automatic calculation of knee point, transformation ratio, polarity, 5% and 10% error curves, demagnetization, primary current injection, angle difference and ratio difference, etc., easily achieving multiple functions in one machine.
5. Simple wiring:
It uses a single power input port; only 8 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. Simple operation:
It adopts a rotary mouse and a large LCD display, with simple operation, clear graphic display, and intuitive convenience.
7. Fast printing:
It uses a thermal printer to automatically filter and print typical report data, which is very suitable for on-site data comparison.
8. Large-capacity FLASH storage: It can store 1000 sets of test data, which can be retained for 10 years after power failure.
9. USB interface: Convenient for connecting to new laptops.
10. Small size and light weight: It is the smallest and lightest among similar products, convenient for on-site use.
CT steady-state and transient testing:
1. Volt-ampere characteristic test
2. Transformation ratio test
3. Polarity discrimination
4. 5% and 10% error curves
5. Demagnetization
6. Knee point calculation
7. Primary current injection
