1. Domestic first 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, posing significant safety hazards, easily causing electric shock or even casualties. 2. Compliant with national maintenance regulations:
All equipment power outputs are 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, meeting relevant national maintenance regulations.
3. Large output capacity:
With single-unit 220V input, maximum voltage output is 0-2500V, and maximum current output is 0-400A.
4. Full functionality:
Can test CT steady-state/transient characteristics: volt-ampere characteristics, automatic knee point calculation, 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:
Uses a single power input port; only 8 test ports are needed to complete all CT test items, with safe and simple wiring, very suitable for field use, effectively reducing labor intensity and improving work efficiency;
6. Easy operation:
Uses a rotary mouse and large LCD display, with simple operation, clear graphic display, intuitive and convenient.
7. Fast printing:
Uses a thermal printer, automatically filters and prints typical report data, very suitable for on-site data comparison.
8. Large-capacity FLASH storage: can save 1000 sets of test data, and data can be retained for 10 years after power off.
9. USB interface: convenient for connecting to new laptops.
10. Small size, light weight: the smallest and lightest among similar products, convenient for field use.
CT steady-state and transient testing:
1. Volt-ampere characteristic test
2. Ratio test
3. Polarity discrimination
4. 5% and 10% error curves
5. Demagnetization
6. Knee point calculation
7. Primary current injection
