Coil equipment Tester

HDFT-III automatic transformer comprehensive tester


Performance characteristics:

1. Comprehensive functions, which not only meet the excitation characteristics (ie volt-amp characteristics), transformation ratio, polarity, secondary winding resistance, secondary load, ratio difference, and The angle difference and other test requirements can also be used to test the excitation characteristics, transformation ratio, polarity, secondary winding resistance, ratio difference and angle difference of various PT electromagnetic units.

2. The inflection point voltage/current, 10% (5%) error curve, accuracy limit factor (ALF), instrument security factor (FS), secondary time constant (Ts), remanence factor (Kr), saturation are automatically given And CT, PT parameters such as unsaturated inductance.

3. The test meets various transformer standards such as GB1208 (IEC60044-1), GB16847 (IEC60044-6), GB1207, etc., and 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 deal with CT test with inflection point up to 30KV.

5. The interface is friendly and beautiful, with a Chinese graphical interface.

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