Instrument Introduction:
The fully automatic transformer characteristic comprehensive tester is specially designed for relay protection professionals to test the volt-ampere characteristics of current transformers, 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 high-quality materials and specially wound voltage boosters. A single-chip 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 machine is lightweight, easy to operate, and has unique performance, making it an indispensable instrument for field personnel.
Instrument Features:
1. Single power supply 220VAC, safer and more reliable (completely abandoning the dangerous 380V live wire);
2. Single unit output 2500V/1000A;
3. Can test transformers with ratios 5A/5A—25000A/5A and 5A/1A—5000A/1A;
4. Only need to set the test voltage and current, and the device will 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, 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-off 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 identification, only need digital setting. Set the maximum test voltage, maximum current, and step size, and the device will automatically increase voltage from zero step by step. It can automatically test and plot the volt-ampere characteristic curve (volt-ampere characteristic, 5% or 10% error curve)
