1、 Product Overview:

The comprehensive characteristic tester for transformers is a new generation of CT and PT testing instruments developed on the basis of traditional transformer volt ampere characteristic variable ratio polarity comprehensive testers based on regulators, boosters, and current transformers. It extensively listens to user opinions, conducts extensive market research, and conducts in-depth theoretical research. The comprehensive characteristic tester for transformers adopts high-performance DSP and FPGA, and advanced manufacturing technology to ensure stable and reliable product performance, complete functions, high degree of automation, and high testing efficiency. It is a professional testing instrument used for transformers in the power industry.

2、 Product features:

Fully functional, it not only meets the testing requirements for 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, etc. of various PT electromagnetic units.

On site verification of current transformers does not require the use of standard current transformers, current transformers, load boxes, voltage regulation control boxes, or high current wires. The use of extremely simple testing wiring and operation to achieve current transformer verification reduces work intensity and improves work efficiency, making it convenient to carry out on-site sensor verification work.

The maximum allowable error for accurately measuring the ratio difference and angle difference ratio difference is ± 0.1%, and the maximum allowable error for angle difference is ± 5 minutes. It can be used for on-site testing of 0.2S-level current transformers with a ratio measurement range of 1-40000.

Based on advanced frequency conversion method to test CT/PT volt ampere characteristic curve and 10% error curve, the maximum output AC voltage of only 180V and AC current of 12Anms (peak value of 36A) can cope with CT testing with inflection points up to 60KV.

Automatically provide CT and PT parameters such as inflection point voltage/current, 10% (5%) error curve, accuracy limit factor (ALF), instrument safety factor (FS), quadratic 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 type and level of transformer.

The testing is simple and convenient, allowing for one click completion of CT direct resistance, excitation, transformation ratio, and polarity testing. In addition to load testing, all other CT tests use the same wiring method.

The fully Chinese dynamic graphical interface can complete wiring and parameter setting without referring to the manual: the dynamic display parameter setting automatically displays its relevant parameters based on the currently selected test project; Dynamically display the wiring diagram to assist in displaying the corresponding wiring diagram based on the currently selected test project.

5.7-inch graphic reflective LCD with clear visibility under sunlight.

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

The panel comes with a built-in printer that can automatically print the generated test report.

The test results can be easily and quickly exported using a USB drive.

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

The device can store 1000 sets of test data without loss in case of power failure.

Easy to carry device with a weight of less than 9Kg.
