2. Automatically give CT, VT parameters, including knee point voltage / current, 10% error curve, the accuracy limit factor (ALF), instrument security factor (FS), the second time constant (Ts), remanence coefficient (Kr), saturated and unsaturated inductance etc.3. Test meet IEC60044 GB1208 (-1) GB16847 (IEC60044-6) became etc all kinds of transformer standards, and in accordance with the transformer types and levels of automatic choose which standard test.4. Based on the advanced low-frequency method to test principle of, it can deal with CT test with inflection point up to 30kV.5. Interface friendly and beautiful, Chinese graphics interface.6. The device can store 2000 sets of test data without loss when power is lost.After the test, use U disk to store it on the PC, analyze the data with the software, and generate WORD report.7. The test is simple and convenient. The direct resistance, excitation, ratio change and polarity tests of CT are completed with one key. Besides the load test, all other tests of CT adopt the same wiring mode.8. The weight of the device is easy to carry.
