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, employs the internal fault frequency response analysis currently being developed and refined in developed countries worldwide.(FRA)Methodology for Accurate Diagnosis of Internal Faults in Transformers

Upon completion of transformer design and manufacturing, its winding and internal structure are finalized. Therefore, for a multi-winding transformer, if the voltage level and winding method are the same, each winding corresponds to specific parameters.(Ci、Li)It should be determined. Therefore, the frequency domain characteristic responses of each coil are accordingly determined, and the frequency spectra of the corresponding three-phase coils exhibit certain comparability.

Transformers may experience inter-turn or phase-to-phase short circuits during testing or collisions during transportation, leading to 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 you would like translated into American English..Certainly!Transformer Winding Frequency Response Tester, a novel non-destructive internal fault detection equipment for transformers.

The Frequency Response Transformer Winding Deformation Tester quantifies the response variations of transformer internal winding parameters across different frequency domains. Based on the magnitude of the change, the amplitude of the frequency response variation, the region, and the trend of the frequency response change, it determines the degree of change in the transformer's internal winding. Subsequently, the measurement results can be used to judge whether the transformer has been severely damaged and whether a major overhaul is necessary.

For transformers in operation, whether or not there are previously saved frequency domain feature maps, the degree of fault can be assessed by comparing the differences in the feature maps between the faulty transformer coils. Of course, if original winding feature maps of the transformer are available, it is easier to provide a more comprehensive analysis of the transformer's operating condition, post-accident analysis, and maintenance inspection.Please provide the Chinese content to be translated..No content provided for translation.Compelling Evidence.
