3. The built-in adjustable voltage (current) source has ample power: with only a single 220V power input, the built-in segmented adjustable voltage source allows for selecting different output voltages for transformers with different test voltages, providing finer voltage adjustment, eliminating current jumps, and improving measurement accuracy. The built-in booster can output up to 1250V (Type A: 2000V, Type B: 2500V), the built-in adjustable current source can output up to 800A, and the external current booster can output up to 2000A.
4. User-friendly interface: It adopts an imported all-weather large-screen graphic LCD, which is clearly visible under various strong or weak light conditions. The full Chinese menu interface, cursor prompts for operation, real-time display of test data and curves, and auto-scaling of curve coordinates make reading graphs clearer.
5. Advanced data processing: It has a built-in super-large capacity memory that can store 6400 sets of test data; it can be uploaded to a PC via RS232 or USB interface. Using the random software developed by our company, it can automatically generate editable typical test reports, and can calculate, analyze, and compare the 5% and 10% error curves for CTs of 1A and 5A, facilitating technical management and archiving.
6. Adopts intelligent fuzzy control voltage regulation: automatically identifies non-test segments and quickly returns to zero; significantly shortens test time and improves work efficiency.
7. Comes with a high-speed micro printer: can print CT volt-ampere characteristic test reports, excitation characteristic curves, and CT ratio test reports in real-time.
8. Polarity discrimination adopts the DC method recommended by regulations, with audible and visual indication of the discrimination result, which is reliable and intuitive.
9. Comprehensive protection functions: This machine has complete overcurrent and overvoltage protection functions, and can automatically adjust the overcurrent and overvoltage protection values according to the test parameter settings to ensure the safety of the equipment under test.
