Abstract :
Close-in Short-circuit is one of the most severe fault of the main transformer. It can cause insulation damaged, winding deformation and even completely damaged. So, how to control the influence of the near-range Short-circuit on a running transformer is the most important problem in the power system now. In this paper, its mechanism and influence to transformer has analyzed, and the technical approach to improve this trouble has been presented with the typical example of fault.
