← ScienceWhich outcome occurs when a dielectric material contaminates transformer oil?
A)Reduced dielectric breakdown strength✓
B)Increased core magnetic saturation
C)Enhanced heat dissipation capacity
D)Improved winding insulation integrity
💡 Explanation
Reduced dielectric breakdown strength results because contamination introduces charge carriers that enhance the electrical field, thus lowering the breakdown voltage of the fluid, rather than increasing its integrity or thermal capacity.
