Transformer Winding Deformation Tester

Transformer Winding Deformation Tester Using Frequency Response Method Product Introduction

 The Frequency Response Transformer Winding Deformation Tester, based on the measurement of characteristic parameters of the transformer's internal windings, utilizes the internal fault frequency response analysis currently being developed and refined in developed countries worldwide.(FRA)Method accurately identifies internal transformer faults.

Upon completion of transformer design and manufacturing, its coil and internal structure are finalized. Therefore, for a transformer with multiple windings, if the voltage levels and winding methods are identical, each coil corresponds to specific parameters.(Ci、Li)It should be determined. Consequently, the frequency domain characteristic responses of each coil are also set, and the frequency spectra between the three-phase coils exhibit a certain comparability.

During the testing process, transformers may experience inter-turn and inter-phase short circuits, or collisions during transportation, causing relative displacement of the windings. Additionally, during operation, electromagnetic forces can cause deformation of the windings in short-circuit and fault conditions. This can alter the distribution parameters of the transformer's winding. Consequently, it affects and modifies the transformer's original frequency-domain characteristics, such as changes in amplitude of frequency response and shifts in resonant frequency points. And based on response analysis methods, developed and...Please provide the Chinese content to be translated..No Chinese content provided for translation.Transformer Winding Frequency Response Tester, such is a novel non-destructive testing device for internal transformer faults.

The Frequency Response Method Transformer Winding Deformation Tester quantifies the response variations of transformer internal winding parameters across different frequency domains. By analyzing the magnitude of the change, the amplitude of the frequency response variation, the area, and the trend of the frequency response variation, it determines the degree of change in the transformer's internal winding. Subsequently, based on the measurement results, it can be assessed whether the transformer has suffered severe damage and whether a major overhaul is necessary.

For transformers in operation, whether or not there is a stored frequency domain characteristic map, the degree of fault can be judged by comparing the differences in the characteristic图谱 between the transformer coils. Of course, if there is a set of original winding characteristic maps for the transformer, it is easier to provide more for the transformer's operating conditions, post-accident analysis, and maintenance and repair.Please provide the Chinese content to be translated..Certainly!Compelling evidence.
