Instrument Introduction:
The Automatic Transformer Characteristics Comprehensive Tester is specifically designed for relay protection professionals to test current transformer volt-ampere characteristics, ratio testing, and polarity discrimination. It can also be used for transformer polarity discrimination testing, making it a multifunctional test instrument with a high performance-to-price ratio.
The Automatic Transformer Characteristics Comprehensive Tester uses high-efficiency, low-consumption quality materials and a specially wound booster. A microcontroller microprocessor performs data acquisition, analysis, and storage. It has a built-in micro printer that can print test data and curves. When measuring CT ratio, it can automatically calculate the ratio value. One person can complete all testing work. This instrument is lightweight, easy to operate, and has unique performance, making it an indispensable tool for field personnel.
Instrument Features:
1. Single power supply 220VAC, safer and more reliable to use (completely abandoning the dangerous 380V live wire);
2. Single unit output 2500V/1000A;
3. Can test transformers with ratios 5A/5A—25000A/5A, 5A/1A—5000A/1A;
4. Only need to set the test voltage and current, the device can automatically and quickly complete the test, no training required, easy to master;
5. Large output capacity, full functions, high accuracy, and unique performance;
6. 320×240 large LCD display with full Chinese graphical interface;
7. Uses imported rotary mouse, making setting test values faster and simpler;
8. During testing, the volt-ampere curve can be directly displayed, with clear graphics, intuitive and convenient;
9. Comes with a fast printer, supporting on-site printing of test results;
10. Comes with a large-capacity memory that can save 1000 sets of test data, which will not be lost after power failure and can be accessed at any time;
11. USB communication interface, convenient for connecting to new laptops, can upload test data for editing, saving, or printing;
12. Integrates multiple instrument functions into one, easily achieving multi-purpose use, effectively improving work efficiency and reducing labor intensity.
13. Supports offline and online testing;
14. Power supply 380VAC and 220VAC automatic recognition, only need to set digitally the maximum test voltage, maximum current, and step size, and the device will automatically increase voltage from zero step by step. It can automatically plot the volt-ampere characteristic curve (volt-ampere characteristics, 5% or 10% error curve).
