Comprehensive Characteristics Tester for Current Transformers
Darui Electric recommends
The Comprehensive Characteristics Tester for Current Transformers integrates our five years of production experience, incorporating the best of various approaches, discarding the flashy, highlighting practicality, and offering comprehensive functions. It features high reliability, easy operation, accurate measurement, and compact and lightweight design. It can easily and conveniently test the volt-ampere characteristics, transformation ratio, and polarity of transformers.
Functions and Features
1. Automatic testing: Simply set test parameters such as current step size, and the tester automatically collects volt-ampere characteristic data of the transformer and automatically plots the excitation characteristic curve; automatically tests and calculates the CT transformation ratio.
2. Utilizes the "one-key jog dial" (rotary mouse) technology for more convenient operation.
3. Built-in adjustable voltage (current) source with ample power: Only a single 220V power input is required. The built-in segmented adjustable voltage source allows selection of 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 (SB-HG806A type: 2000V, SB-HG806B type: 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: Uses an imported all-weather large-screen graphic LCD, clearly visible under various strong or weak lighting conditions. Full Chinese menu interface with cursor prompts for operation, real-time display of test data and curves. The curve coordinates auto-scale for clearer reading.
5. Advanced data processing: Built-in super-large capacity memory can store 6400 sets of test data. Data can be uploaded to a PC via RS232 or USB interface. The bundled software developed by our company can automatically generate editable typical test reports, and can calculate, analyze, and compare 5% and 10% error curves for 1A and 5A CTs, facilitating technical management and archiving.
6. Adopts intelligent fuzzy control voltage regulation: Automatically identifies non-test segments and quickly returns to zero, significantly reducing test time and improving work efficiency.
7. Comes with a built-in micro high-speed printer that can print CT volt-ampere characteristic test reports, excitation characteristic curves, and CT transformation ratio test reports in real-time.
8. Polarity discrimination uses the DC method recommended by regulations, with audible and visual indication of the discrimination result, ensuring reliability and intuitiveness.
9. Comprehensive protection functions: This device has complete overcurrent and overvoltage protection functions. It can automatically adjust the overcurrent and overvoltage protection values based on the test parameter settings to ensure the safety of the equipment under test.
