TKRZ-2009 Transformer Winding Deformation Tester adopts the internal fault frequency response analysis which is being developed and perfected by developed countries in the world based on the measurement of the characteristic parameters of the internal winding of the transformer.

(FRA) method, can make accurate judgments on the internal fault of the transformer. After the transformer is designed and manufactured, its coil and internal structure are determined, so for a multi-winding transformer coil

If the voltage level is the same and the winding method is the same, the corresponding parameters (Ci, Li) of each coil should be determined. Therefore, the frequency domain characteristic response of each coil is also determined, and the corresponding three-phase line

There is a certain degree of comparability among the frequency maps.

        The transformer has a short circuit between turns and phases during the test, or collision occurs during transportation, which causes the relative displacement of the coil, and the short-circuit and fault conditions during operation are caused by electromagnetic pull.

The force causes the coil to deform, which will change the distribution parameters of the transformer winding. This in turn affects and changes the original frequency domain characteristics of the transformer, that is, the amplitude change of the frequency response and the shift of the resonance frequency point, etc.

. The transformer winding tester developed based on the response analysis method is such a novel non-destructive testing equipment for transformer internal faults. It is suitable for 63kV～500kV power transformer

Internal structure failure detection.

       TKRZ-2009 Transformer Winding Deformation Tester is to quantify the response changes of the internal winding parameters of the transformer in different frequency domains, and then according to the magnitude of the change and the magnitude of the frequency response change.

, Area and frequency response change trend, to determine the degree of change of the transformer's internal windings, and then can judge whether the transformer has been severely damaged or need to be overhauled according to the measurement results. Correct

Regarding the transformer in operation, whether or not there is a frequency domain characteristic map saved in the past, the degree of fault can also be judged by comparing the difference in the characteristic map between the coils of the faulty transformer. Of course, such as

If there is a set of original winding characteristic diagrams of the transformer, it is easier to provide a more accurate and powerful basis for the operation status of the transformer, post-accident analysis, maintenance and repair. Transformer winding deformation tester by

The notebook computer and the single-chip microcomputer constitute a high-precision measurement system with tight structure, simple operation, and a relatively complete test and analysis function. It can be operated and used by itself according to the instruction manual or after short-term training.
