Instrument Introduction:
The fully automatic transformer characteristic comprehensive tester is specially 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. It is a multifunctional test instrument with a high performance-to-price ratio.
The fully automatic transformer characteristic comprehensive tester adopts high-efficiency, low-consumption quality materials and specially wound boosters. 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 test work. This machine has the advantages of light weight, easy operation, and unique performance, making it an indispensable instrument for field personnel.
Instrument Features:
1. Single power supply 220AC, safer and more reliable to use (completely abandoning the dangerous 380V live wire);
2. Single unit output 2500V/1000A;
3. Can test transformers with 5A/5A—25000A/5A, 5A/1A—5000A/1A;
4. Only need to set the test voltage and current, the device will automatically and quickly complete the test, no training required, easy to master;
5. Large output capacity, full functions, high precision, and unique performance;
6. 320×240 large LCD display, 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 to connect to new laptops, can upload test data for editing, saving, or printing;
12. Integrates multiple instrument functions into one, easily achieving multiple uses with one machine, effectively improving work efficiency and reducing labor intensity.
13. Supports offline and online testing
14. Power supply 380AC and 220AC automatic identification, only need digital setting, set the maximum test voltage, maximum current, and step size, the device will automatically increase voltage from zero step by step. It can fully automatically test and plot the volt-ampere characteristic curve (volt-ampere characteristic, 5% or 10% error curve)
