1.Comprehensive functions, which not only meet the excitation characteristics (ie volt-ampere characteristics), transformation ratio, polarity, secondary winding resistance, secondary load, ratio difference and angular difference of various CTs (such as protection, measurement, TP) It can also be used to test the excitation characteristics, transformation ratio, polarity, and secondary winding resistance of various PT electromagnetic units.

2.Inflection point voltage/current, 10% (5%) error curve, accuracy limit factor (ALF), instrument security factor (FS), secondary time constant (Ts), remanence factor (Kr), saturation inductance, etc. are automatically given CT and PT parameters.

3. Comply with various transformer standard such as IEC 60044-1, IEC 60044-6，automatically selects which standard for testing according to the type and level of the transformer.

4.Based on the advanced low-frequency method test principle, it can cope with CT tests with inflection points as high as 40KV.

5. Adopts the international popular square wave method.

6.Data storage up to hundred thousand sets, no lost when power off. Generate an Excel report directly after the experiment is completed.

7.The test is simple and convenient. The direct resistance, excitation, transformation ratio and polarity test of CT can be completed with one press. all other CT tests use the same wiring method except load test.

8.Portable, only 6 KG.
