Product Features

 

Fully functional, it not only meets 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 various CTs (such as protection, metering, TP), but also can be used for testing excitation characteristics, transformation ratio, polarity, secondary winding resistance, ratio difference, and angle difference of various PT electromagnetic units.

 

Automatically provide 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 based on the type and level of the transformer.

 

The interface is friendly and beautiful, with a Chinese graphical interface.

 

The device can store 2000 sets of test data without losing power. After the experiment is completed, use a USB flash drive to store it in a PC, use software to analyze the data, and generate a WORD report.

 

The testing is simple and convenient, with one click to complete CT direct resistance, excitation, transformer ratio, and polarity testing. In addition to load testing, all other CT tests use the same wiring method.

 

On site calibration of current transformers does not require standard current transformers, current transformers, load boxes, voltage regulating control boxes, and high current conductors. Simple testing wiring and operation are used to achieve current transformer calibration, reducing work intensity and improving work efficiency, making it convenient for on-site transformer calibration work.

 

It can accurately measure the ratio difference and angle difference of the transformer, with a maximum allowable error of ± 0.02% for the ratio difference and ± 2min for the angle difference. It can be used for measuring 0.2S level current transformers, with a ratio measurement range of 1 to 30000.

 

Based on the frequency conversion method to test the CT/PT volt ampere characteristic curve and 10% (5%) error curve, output a maximum AC voltage of 180V and an AC current of 12Arms (36A peak). Based on the low-frequency testing principle, it can handle CT testing with inflection points up to 45KV.

 

Chinese dynamic graphical interface, no need to refer to the manual to complete wiring and parameter settings: dynamic display parameter settings, automatically displaying relevant parameters based on the currently selected test project; Dynamically display the help wiring diagram, displaying the corresponding wiring diagram based on the currently selected test project.

 

6.7-inch graphic reflective LCD, clear and visible in sunlight.

 

Adopting a rotating photoelectric mouse operation, the operation is simple, fast, convenient, and easy to master.

 

The panel comes with a printer that can automatically print generated test reports.

 

The test results can be exported from a USB drive, and the program can be upgraded from a USB drive, making it convenient and fast.

 

The device can store 2000 sets of test data without losing power.

 

Equipped with backend analysis software, it facilitates the storage, conversion, and analysis of test reports, and can be used for comparison, judgment, and evaluation of experimental data.
