Features: 1. Full-featured to meet the excitation characteristics (volt-ampere characteristics), ratio, polarity, secondary winding resistance, secondary load, ratio difference, and angle difference of various types of CT (protection, metrology, TP) Such test requirements, but also for various types of PT electromagnetic unit excitation characteristics, transformation ratio, polarity, secondary winding resistance test. 2. Automatically give corner voltage/current, 10% (5%) error curve, accurate limit factor (ALF), instrument security factor (FS), secondary time constant (Ts), remanence factor (Kr), saturation inductance, etc. 3. The test meets various types of transformer standards such as GB1208 (IEC60044-1), GB16847 (IEC60044-6), and GB1207, and tests are automatically selected according to the type and level of the transformer. 4. Based on the advanced low-frequency test principle, it can deal with CT tests with inflection points up to 30KV. 5. The device uses the international
