| Transformer Ratio Polarity Tester |
Introduction:
1. The instrument is safe and convenient to operate. It is a fully computerized device with a built-in imported high-performance CPU, ensuring high reliability. After setting the test values according to the interface prompts, there is no need for manual contact with the tested equipment. The instrument automatically completes the test, keeping test personnel away from high-voltage circuits and ensuring their personal safety.
2. Large output capacity: the maximum output voltage for volt-ampere characteristic tests is up to 1000V, the maximum current for ratio tests is up to 600A, and the output capacity of the instrument is 5KVA.
3. Optional accessories include an external booster, an external current booster, and an external voltage regulator. The external booster can increase the voltage up to 2000V, 3A; the external current booster can increase the current up to 1000A; the external voltage regulator can output up to 1500V, 20A. When using the external booster, volt-ampere characteristic tests can be performed on current transformers of up to 500KV class 1A.
Features:
1. Only need to set the test voltage, current, and step size. The device will automatically increase the voltage and automatically plot the volt-ampere characteristic test curve, eliminating tedious tasks such as manual voltage adjustment, manual recording, and curve drawing. It is fast, simple, and convenient;
2. An innovative wiring method is adopted with adaptive voltage input. Only four binding posts are needed to complete all tests for CT/PT;
3. Comprehensive functions: it can test CT/PT volt-ampere characteristics, ratio and polarity, CT 5% and 10% error curves, CT secondary circuits, and AC withstand voltage tests;
4. If the output voltage of the standalone unit cannot meet the requirements, an external booster can be used for testing;
5. For volt-ampere characteristic tests, the standalone unit outputs voltage 0-1000V and current 0-650A; with an external booster, the output voltage is 0-2500V, allowing volt-ampere characteristic tests on transformers of 500KV class 1A;
6. Large-screen LCD display shows the volt-ampere curve directly during testing, which is intuitive and convenient. A built-in micro printer can print the curve and test data at any time;
7. Full keyboard operation input makes test operation simple and convenient;
8. Equipped with a large-capacity memory that can store 100 sets of test data, which is not lost even when power is off;
9. RS232 communication interface allows connection to a computer for testing, and test data can be uploaded to the computer for editing and saving;
10. Small size, light weight, convenient for mobile testing.
