PRODUCT DESCRIPTION

ZCCTP-1000
CT/PT Analyzer
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), GB16847 (IEC60044-6), GB1207 and other kinds of transformers.
4. With full English dynamic graphical interface, it can complete wiring and parameters setting without reference to manual. It can conduct dynamic display of parameter settings and automatic display of relevant parameters according to the currently selected test item. It also can conduct dynamic display of wiring diagram, and display corresponding wiring diagram according to the currently selected test item.
5. 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.
 
6. It is easy to use. To test CT DC resistance, excitation and polarity only need one button. All CT tests adopt same one connect method except load test.
 
7. Panel comes with printer, can automatically print the test report .The test results can be exported with USB disk, and program can be upgraded with USB disk, convenient and quick. It can store 1000 groups of test data, and data will not lose during power failure. With background analysis software to facilitate the test report of the preservation, conversion, analysis, can be used to test data comparison, judgment and evaluation.
