The Application of Frequency Response Analysis in Online Testing System of Transformer

摘要：

　　Online testing system based on frequency response analysis is proposed for the deformation of transformer winding.The structure of testing system,the selection of sweep sequence and computer diagram of data acquisition system are developed in the course of design.In the process of analysis,the concept of correlation coefficient is introduced to judge the relationship between the deformation extent and correlation coefficient.With the proposed method,the location of deformation can be determined.The testing curves demonstrate the effectiveness of the presented system.
