Product parameters

-------------------------------------------------------------------------------

★ it has comprehensive functions, which can not only meet the testing requirements of excitation characteristics (i.e. volt ampere characteristics), transformation ratio, polarity, secondary winding resistance, secondary load, ratio difference and angle difference of all kinds of CT (such as protection, measurement and TP), but also be used for the testing of excitation characteristics, transformation ratio, polarity, secondary winding resistance, ratio difference and angle difference of all kinds of Pt electromagnetic units.
★ automatically give CT and Pt parameters such as inflection point voltage / current, 10% (5%) error curve, accuracy limit factor (ALF), instrument security factor (FS), secondary time constant (TS), remanence coefficient (KR), saturated and unsaturated inductance.
★ the test meets various transformer standards such as gb1208 (iec60044-1), gb16847 (iec60044-6), GB1207, and automatically selects which standard to test according to the transformer type and level.
★ friendly and beautiful interface, all Chinese graphical interface.
★ the device can store 2000 groups of test data without losing power. After the test, store it in PC with U disk, analyze the data with software, and generate word report.
★ the test is simple and convenient. The CT direct resistance, excitation, transformation ratio and polarity tests are completed with one key. Besides the load test, other CT tests adopt the same wiring method.
★ the on-site verification of current transformers does not require standard current transformers, current risers, load boxes, voltage regulation control boxes and high current conductors. The use of extremely simple test wiring and operation to achieve the verification of current transformers greatly reduces the working intensity and improves the working efficiency, which is convenient for the on-site verification of transformers.
★ it can accurately measure the transformation ratio difference and angle difference. The maximum allowable error of the ratio difference is ± 0.02%, and the maximum allowable error of the angle difference is ± 2min. It can measure the 0.2S level current transformer, and the transformation ratio measurement range is 1 ~ 30000.
★ based on the advanced frequency conversion method to test the ct/pt volt ampere characteristic curve and 10% (5%) error curve, the maximum 180V AC voltage and 12arms (36a peak) AC current are output. Based on the advanced low-frequency method test principle, it can cope with the CT test with the inflection point as high as 45kV.
★ the full Chinese dynamic graphic interface can complete the wiring and set parameters without referring to the manual: the dynamic display parameter setting automatically displays its relevant parameters according to the currently selected test items; Dynamically display the help wiring diagram, and display the corresponding wiring diagram according to the currently selected test items.
★ 6.7-inch graphic reflective LCD, which is clearly visible in the sun.
★ it adopts rotating photoelectric mouse for operation, which is simple, fast and convenient, and easy to master.
★ the panel is equipped with a printer, which can automatically print the generated test report.
★ the test results can be exported by USB flash disk, and the program can be upgraded by USB flash disk, which is convenient and fast.
★ the device can store 2000 groups of test data without losing power.
★ it is equipped with background analysis software to facilitate the storage, conversion and analysis of test reports, and can be used for the comparison, judgment and evaluation of test data.
