| Abstract: | The cause and behaving of transformer winding deformation are introduced.The characte-ristics and applications of existing off-line and on-line monitoring techniques for winding deformation are emphasized,and their unsolved problems are analyzed and summarized.Depending on the relation between winding deformation and leak inductance,it is pointed that the exact and real-time calculation of leak inductance is the key factor of winding deformation monitoring,especially of the technique development from off-line monitoring to on-line monitoring. The project is supported by National Natural Science Foundation of China(50277027). |
