Abstract :
This paper examines some theoretical aspects of the relationship between the aging of oil and the deterioration of the internal insulation of the windings, and looks at some new findings that might provoke fresh consideration of the relationship between the analytical properties of liquid insulation and the dielectric properties of windings.
