1.With comprehensive functions, it can satisfy the test requirements of excitation characteristics (i.e. volt-ampere characteristic) of all kinds of CT (such as: protection, measurement, TP), transformation ratio, polarity, secondary winding resistance, secondary load, ratio error, angular error and also can be used for the test of the excitation characteristics of all kinds of PT electromagnetic unit, transformation ratio, polarity, secondary winding resistance, ratio error, etc.
2.On site calibration of current transformer doesn't need the standard current transformer, strong current generator, load box, voltage regulation control box and high-current conductor, and only very simple test wiring and operation can realize the calibration of current transformer, greatly reducing the working intensity and improving the work efficiency, and facilitating the on site calibration of current transformer.
3.It can measure ratio error and angular error accurately. Max ratio error ±0.05% is permitted. Max angular error ±2min is permitted. It can measure 0.2S class current transformer and turns ratio range is 1~40000.
4.Current output 180A after selecting our dedicated strong current generator, convenient for on-site flow test.
5.It can test CT/PT volt-ampere characteristic curve and 10% error curve based on the advanced frequency conversion method, only output maximum 180V of AC voltage and 12Ams (36A peek value) of AC current, but can cope with the CT test with inflection point of as high as 60Kv.
6.Auto test CT/PT parameters on knee point voltage/current, 5% and 10% deviation curve measurement, accuracy limit factor (ALF), safety factor (FS), second time constants (Ts), residual magnetism factor (Kr), saturated and unsaturated inductance.
