Technical characteristics

Based on the frequency conversion method to test the volt ampere characteristic curve of CT, the maximum output is only 180V AC voltage and 12A AC current, but it can withstand CT testing with a turning point of up to 30kV.

Meet the steady-state or transient characteristic tests of excitation, transformation ratio, phase, polarity, secondary winding resistance, load, ratio difference, and angle difference for various types of CT (including high inflection point, large transformation ratio, and transformer bushing CT).

CT can be tested and analyzed in accordance with standards such as GB20840, GB1208 (IEC60044-1), and GB16847 (IEC60044-6),automatically providing parameters such as inflection point voltage/current, 10% error curve, 5% error curve, accuracy limit factor (ALF), instrument safety factor (FS), secondary time constant (Ts), residual magnetic coefficient (Kr), accuracy level,saturated and unsaturated inductance.

With just one test, the angle difference and specific difference of CT under 1%~120% rated current and different loads can be obtained, and the test results can also be extended to other current ranges and loads.

Can test the actual load and power factor of the transformer.

Can complete the excitation test, transformer ratio test, and polarity check of electromagnetic PT.

The interface is user-friendly and beautiful, with a Chinese graphical interface and a 5.7-inch transparent LCD display. It can be viewed under sunlight.

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

The device can store 1000 sets of test data without losing power. It can be exported in real-time through a USB flash drive, and historical data can also be retrieved for analysis and comparison.

Provide upper computer software as a gift, generate Word format test reports, and achieve functions such as variable parameter analysis, cursor reading, and curve comparison.

The device is lightweight and portable, with a built-in printer on the panel that can automatically print generated test reports.
