The KDHG-F1 transformer comprehensive characteristic tester is a multifunctional on-site testing instrument designed specifically for testing transformers, including volt ampere characteristics, transformation ratio, polarity, error curve, calculation inflection point, AC withstand voltage, and secondary side circuit inspection.

1. Support the detection of steady-state and instantaneous parameters of CT and PT (protection and measurement)
2. Supports USB flash drive data transfer, which can be read through a standard PC and generate WORD reports
3. Measurement of CT and PT parameters such as coefficients, accuracy levels, saturated and unsaturated inductance.
4. It has a one click automatic testing function. Press the test button to automatically test the CT secondary direct resistance, variable ratio polarity, angle difference ratio, magnetization curve, and 10% (5%) error curve in order, and print the test report synchronously.
