| Abstract |
| As we know that one of the most important equipment in power system, transformer plays a major role for stable operation of the power system. The transformer working under high and medium voltage network influences various stresses under working condition. As the ageing processes or minor faults on the transformer can cause the core deformation which leads to change the mechanical and electrical properties of the transformer. Sweep frequency response analysis (SFRA) is used as a tool for detection of core deformation or mechanical deterioration in transformer which is due to large electromechanical forces occurring from the fault currents or due to transportation and relocation of transformer. In this method, the frequency responses of a transformer is taken both at manufacturing industry and concern site. Then both the response is compared to predict the fault taken place in active part. But in old aged transformer, this response is not possible. So Cross Correlation Co-Efficient (CCF) measurement technique can be a suitable process for fault detection in these transformers. These two methods are mostly used to identify the winding displacement This paper briefs about the mechanical core deformation in 1KVA, 3-phase laboratory manufactured transformer (both of same rating) which includes different tests results of healthy as well as core deformed transformer. The test results of healthy transformer is compared with core deformed transformer for analyzing the effects of core deformation. |
