What transformers can be tested by the transformer winding deformation tester

The transformer winding deformation tester is suitable for detecting transformers of various voltage levels and types, as follows:

1. Divided by voltage level

① Power transformers with voltage levels of 6kV and above

Suitable for conventional power distribution systems and industrial scenarios, it evaluates the mechanical stability of windings by detecting their deformation under short-circuit current or mechanical shock.

② 63kV~500kV high-voltage power transformer

For the core equipment of the power transmission and transformation system, the focus is on detecting structural damage such as winding displacement and distortion caused by transportation collisions, long-term operation, or faults.

2. Divided by application scenarios

① Transformer in operation

By comparing the historical frequency domain feature maps with the current detection results, it is determined whether there is deformation in the winding, providing a basis for state maintenance.

② Transformer after malfunction

Analyze the differences in characteristic maps between coils and quickly diagnose the degree of winding deformation caused by faults such as inter turn short circuits and inter phase contact short circuits.

③ Transformer after transportation

Detect the relative displacement of coils caused by collisions during transportation to avoid operational risks due to concealed damage.

3. Coverage range according to technical parameters

① Frequency response analysis (FRA) compatibility

Supports dual modes of linear sweep (1kHz-2MHz) and segmented sweep to meet the needs of different technical schools, and is more sensitive to high-frequency deformation characteristics.

② Dynamic measurement range

The amplitude measurement accuracy reaches 0.1dB, covering a range of -100dB to+20dB, and can accurately capture the frequency response curve deviation caused by small deformations.

③ Anti-interference ability

Adopting 5000V voltage isolation technology ensures that the test signal is not affected by strong electromagnetic field interference and guarantees data reliability under complex working conditions.

4. Scalability based on detection function

① Multi winding synchronous detection

It can simultaneously load 6-9 curves for horizontal/vertical comparison, automatically calculate the parameters of each winding and diagnose the deformation type, improving the detection efficiency of multi winding transformers.

② Adaptive environmental parameters

Automatically save test environment condition parameters, and adjust frequency response characteristics using temperature compensation algorithms to ensure comparability of detection results under different operating conditions.

③ Intelligent diagnostic system

Integrated expert diagnostic module can automatically identify typical deformation modes such as distortion, bulging, and displacement, and provide repair recommendations.

ZC-206A transformer winding deformation tester detects the amplitude frequency response characteristics of each winding of the transformer, compares the detection results vertically or horizontally, and judges the possible deformation of the transformer winding according to the change degree of amplitude frequency response characteristics.
