Product Details

CT Current Transformer Parameter Analyzer

Product Features

 1. Comprehensive functions, meeting the test requirements of various CTs (such as protection, metering, TP types) for excitation characteristics (i.e., volt-ampere characteristics), ratio, polarity, secondary winding resistance, secondary burden, ratio error, and phase error,

and also applicable for testing the excitation characteristics, ratio, polarity, secondary winding resistance, ratio error, etc. of various PT electromagnetic units.

 2. On-site calibration of current transformers does not require standard current transformers, current boosters, load boxes, voltage regulators, and high-current cables. It uses extremely simple test wiring and operations to achieve current transformer calibration,

greatly reducing work intensity and improving work efficiency, facilitating on-site calibration of transformers.

 3. Can accurately measure ratio error and phase error, with maximum allowable error of ratio error ±0.05%, and maximum allowable error of phase error ±2 minutes. It can measure 0.2S class current transformers, with a ratio measurement range of 1 to 40000.

 4. Based on advanced frequency conversion method to test CT/PT volt-ampere characteristic curves and 10% error curves, outputting a maximum AC voltage of only 180V and AC current of 12Arms (36A peak), yet capable of handling CT tests with knee points up to 60KV.

 5. Automatically provides knee point voltage/current, 10% (5%) error curves, accuracy limit factor (ALF), instrument security factor (FS), secondary time constant (Ts), remanence coefficient (Kr), saturated and unsaturated inductance, and other CT and PT parameters.

 6. Tests comply with various transformer standards such as GB1208 (IEC60044-1), GB16847 (IEC60044-6), GB1207, etc., and automatically selects the appropriate standard for testing based on the transformer type and class.

 7. Simple and convenient testing: one-click completion of CT DC resistance, excitation, ratio, and polarity tests. Except for burden test, all other CT tests use the same wiring method.

 8. Full Chinese dynamic graphical interface, no need to refer to the manual for wiring and parameter settings: dynamically displays parameter settings, automatically showing relevant parameters based on the currently selected test item; dynamically displays help wiring diagrams, showing the corresponding wiring diagram based on the currently selected test item.

 9. 5.7-inch graphic transflective LCD, clearly visible under sunlight.

 10. Operated by a rotating optical mouse, simple, fast, and easy to master.

 11. Built-in printer on the panel, can automatically print generated test reports.

 12. Test results can be exported via USB drive, and the program can be upgraded via USB drive, convenient and fast.

 13. The device can store 1000 sets of test data, which will not be lost after power failure.

 14. Equipped with background analysis software, convenient for saving, converting, and analyzing test reports, and can be used for comparison, judgment, and evaluation of test data.

 15. Easy to carry, device weight <9Kg.
