Product Introduction ZCCTP-1000 series transformer analyzer using the testing principle of the DC frequency conversion method, no need of pressure regulatorand up flow device can be on-site to complete the comprehensive test of CT and PT, portable instrument, comprehensive function, the output voltage is low, effectively guarantee the safety of testing personnel. Product Features 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 and angle 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. It can measure ratio error and angular error accurately. Max ratio error ±0.05% is permitted. Max angular error ±2min if permitted. It can measure 0.2S class CT and turns ratio range is 1-40000. 3. It can test CT/PT volt-ampere characteristic curve and 5%、 10% error curve based on the advanced frequency conversion method, only output maximum 180V of AC voltage and 12A AC current, but can cope with the CT test with inflection point of as high as 60 KV. The test can meet GB1208 (IEC60044-1), G
