Comprehensive functionality: it not only meets the excitation characteristics (i.e., volt-ampere characteristics), transformation ratio, polarity, secondary winding resistance, secondary load, ratio difference, and phase angle difference requirements of various CTs (such as protection, measurement, and TP), but also enables testing of the excitation characteristics, transformation ratio, polarity, secondary winding resistance, ratio difference, and phase angle difference of various PT electromagnetic units.
- Inflection point voltage/current, 10% (5%) error curve, accuracy limit factor (ALF), instrument security factor (FS), secondary time constant (Ts), remanence factor (Kr), saturation characteristics, and parameters such as unsaturated inductance.
- The test complies with various transformer standards, including GB1208 (IEC60044-1), GB16847 (IEC60044-6), GB1207, etc. The relevant standard is automatically selected for testing based on the transformer type and rating level.
- Using the advanced low-frequency test principle, it can handle CT testing with an inflection point voltage of up to 45 kV.
- Friendly and user-friendly interface with a fully Chinese graphical interface.
- The device can store up to 2,000 sets of test data without loss after power failure. After the test is completed, data can be saved to a PC via a USB flash drive; the software can then analyze the data and generate a Word report.
- Simple and convenient operation. For CTs, one-key operation supports direct resistance, excitation, transformation ratio, and polarity tests. Except for the load test, all other CT tests use the same wiring method.
- Easy to carry: device weight is <9 kg.
