Transformer winding deformation refers to effect of mechanical or electromotive force on the internal coil windings, which causes irreversible changes in the size and position of the windings, including body displacement, winding distortion, bulging and short circuits between turns, etc.

Why do we need to filter transformer oil regularly？The purpose of transformer oil filtration is to remove moisture and impurities in the oil and improve the breakdown voltage of the oil.It protects the paper insulation in the oil, and can also improve the physical and chemical properties of the oil
