1. Comprehensive function: it can not only test the excitation characteristic / volt ampere characteristic, transformation ratio and polarity of PT, but also can test the secondary load of transformer.
2. Easy to use: just set the maximum voltage and current to be tested, the device will automatically boost the voltage and automatically draw the test curve of excitation characteristic / volt ampere characteristic, and automatically calculate the inflection point.
3. Support PT no-load loss measurement, and automatically calculate no-load loss and power factor during PT excitation characteristic test.
4. 220V single power input, avoid the danger of 380V.
5. During the excitation characteristic / volt ampere characteristic test, the output voltage of a single machine is 0-250V and the current is 0-12A, which can be used for most voltage transformer excitation characteristic / volt ampere characteristic tests.
6. Large screen liquid crystal display, direct display of volt ampere curve during testing, intuitive and convenient. With micro printer, it is easy to print and measure Test data.
7. The number keyboard is used to facilitate the number input.
8. With large capacity memory, it can store 3000 groups of test data, No data loss due to power failure.
9. USB interface, which supports the export of USB data and the upgrade of USB system. Background analysis software can generate reports in excel format.
10. RS232 communication interface can be connected to a computer for testing, and a communication protocol is provided. Users can develop byte upper computer software according to the protocol.
