KDHG102F Transformer Comprehensive Tester is an automated CT/PT characteristic testing instrument, which is a specialized testing instrument for relay protection and high voltage insulation. The tests that the instrument can perform include: CT volt ampere characteristic test, CT ratio polarity test, CT polarity test, CT primary current test, PT volt ampere characteristic test, PT ratio polarity test, PT polarity test, automatic calculation of inflection point voltage and current value, ratio difference value, 5% or 10% error curve value and other result parameters.

1. Fully functional: It can not only test the DC resistance, excitation characteristics/volt ampere characteristics, transformation ratio and polarity, 10%&5% error curve, angle difference, and ratio difference of CT/PT, but also perform transformer secondary load testing, AC withstand voltage testing, and current testing.
2. Easy to use: Simply set the larger voltage and current for testing, and the device will automatically boost and plot the excitation/volt ampere characteristic test curve, automatically calculating the inflection point.
3. Support PT no-load loss measurement, automatically calculate no-load loss and power factor during PT excitation characteristic testing.
4. When testing the CT ratio, it not only supports traditional current method but also voltage method testing, which can meet the testing requirements of casing CT and GIS internal CT.
5. 220V single power input avoids the danger of using 380V.
6. When conducting excitation/volt ampere characteristic tests, a single machine output voltage of 0-2500V and current of 0-20A can meet the excitation/volt ampere characteristic tests of 500kV and 1A transformers.
7. Large screen LCD display, directly displaying the volt ampere curve during testing, intuitive and convenient. Equipped with a micro printer, it is convenient to print test data.
8. Using a numeric keypad for convenient numerical input.
9. Equipped with a large capacity memory, it can store 3000 sets of test data without loss in case of power failure.
10. USB interface, supporting data export from USB flash drive and system upgrade from USB flash drive. The backend analysis software can generate reports in Excel format. RS232 communication interface, can be connected to a computer for testing, and provides a communication protocol. Users can develop upper computer software based on the protocol.
