Abstract

Transformer winding deformation is common in transformer faults. Offline monitoring is mostly used in diagnosis of winding deformation, which has some limitations. So an online detecting method based on extraction of current is proposed. The method increases the higher harmonic of the current that flows into the input end of transformer appropriately. This higher harmonic is regarded as sweep frequency source. Current flowing into the input and outlet end of transformer is measured. And high frequency components are extracted to structure response curves. Transformer winding deformation is diagnosed through the analysis of response curves. The simulation results showed that winding deformation can be reflected effectively in this method.
