Test research on power transformer winding deformation by FRA method
Proceedings of 2001 International Symposium on Electrical Insulating Materials (ISEIM 2001). 2001 Asian Conference on Electrical Insulating Diagnosis (ACEID 2001). 33rd Symposium on Electrical and Electronic Insulating Materials and Applications in System, 2002Frequency response analysis (FRA) is a popular method for the detection of transformer winding deformation due to short circuit. In this paper, the principle of transformer winding deformation is analyzed in theory, and the principle of the FRA method is briefly introduced. With an emphasis on studying the onsite detection method of winding deformation,

Winding deformations detection in power transformers by tank vibrations monitoring
Electric Power Systems Research, 2005There is an increasing interest in applying monitoring systems and on line diagnosis techniques to power transformers, as these are one of the most expensive and critical components of a power system. Detecting failures in an incipient stage can avoid major transformer damages, allowing important savings in investing, and giving time enough to plan ...

Diagnostics of Transformer Windings Deformation Based on Transfer Function
2014The deformation of transformer windings after a short circuit was analyzed by studying the criterion for the transfer function. First, the lumped parameter method was used to establish the equivalent circuit of transformer winding, the losses, and mutual inductance was added in it.
