Automatic Transformer Characteristic Comprehensive Tester
Darui Electric recommends:
The Automatic Transformer Characteristic Comprehensive Tester is also known as transformer tester, volt-ampere characteristic comprehensive tester, transformer characteristic tester, current and voltage transformer tester, CT characteristic tester, PT characteristic tester, etc.
Instrument Features
1. Single power supply 220V AC, safer and more reliable (completely abandoning the dangerous 380V live wire);
2. Single unit output 2500V/1000A;
3. Can test transformers with ratios of 5A/5A—25000A/5A, 5A/1A—5000A/1A;
4. Only need to set test voltage and current, the device can automatically and quickly complete the test, no training required, easy to master;
5. Single unit output capacity is large, full-featured, high precision, unique performance;
6. 320×240 large LCD display, full Chinese graphical interface;
7. Uses imported rotary mouse, making it faster and simpler to set 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, data is not lost after power failure, 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 multi-purpose use, effectively improving work efficiency and reducing labor intensity.
13. Supports offline and online detection
14. Power supply 380V AC and 220V AC automatic recognition, only need to set digital values, set the maximum test voltage, maximum current, and step size, 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)
