Abstract:

A winding deformation of 110 kV transformer in operation is detected and analyzed. Firstly, the situation of winding deformation are preliminary analyzed through capacitance, short circuit impedance and frequency response detection, and then the causes of the accident are analyzed through transformer disassembly inspection and winding material detection. Finally, the corresponding rectification measures are proposed.
