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 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 device is lightweight, easy to operate, and has unique performance, making it an indispensable instrument for field personnel.
Instrument Features:
1. Single power supply 220AC, safer and more reliable (completely abandons 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 test voltage and current, the device automatically completes the test quickly, 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 for faster and simpler setting of test values;
8. During testing, the volt-ampere curve can be displayed directly, with clear graphics, intuitive and convenient;
9. Built-in fast printer supports on-site printing of test results;
10. Built-in large-capacity memory can save 1000 sets of test data, which is not lost after power off and can be accessed at any time;
11. USB communication interface, convenient for connecting new laptops, can upload test data for editing, saving, or printing;
12. Integrates multiple instrument functions into one, easily achieving multiple uses with one device, effectively improving work efficiency and reducing labor intensity.
13. Supports offline and online testing;
14. Power supply 380AC and 220AC automatic recognition, only need digital setting of maximum test voltage, maximum current, and step size, the device automatically increases voltage from zero step by step. It can automatically draw the volt-ampere characteristic curve (volt-ampere characteristics, 5% or 10% error curve).
