Distribution of defect types by component.

Part	Single defect
Body	Winding interturn short circuit	Winding deformation
	Iron core multipoint grounding	Partial discharge
	Aging of oil paper insulation	Arc discharge
	Current circuit overheating	Wetted insulation
Bushing	Thermal performance of the bushing decreases	Insulation performance of the bushing decreases
	Mechanical performance of the bushing decreases
