HQ-2000B Frequency Conversion Transformer Comprehensive Tester
★Comprehensive functions, which not only meet the test requirements of the excitation characteristic transformation ratio, polarity, secondary winding resistance, secondary load, ratio difference and angular difference of various CTs, but also can be used for the excitation characteristics and transformation ratios of various PT electromagnetic units , Polarity, secondary winding resistance, etc. test.
★ The inflection point voltage/current, 10% (5%) error curve, accuracy limit factor (ALF), instrument security factor (FS), secondary time constant (Ts), residual magnetic coefficient (Kr), etc. are automatically given , PT parameters.
★ The test meets various transformer standards such as GB1208 (IEC60044-1), GB16847 (IEC60044-6), GB1207, etc., and which standard is automatically selected for testing according to the type and level of the transformer.
★ Based on the advanced low-frequency method test principle, it can handle the CT test with the inflection point as high as 30KV.
★ One key to complete the CT direct resistance, excitation, transformation ratio and polarity test, using the same wiring method.
★ Easy to carry, the weight of the device is less than 8.2Kg.
