Which mechanism causes accelerated degradation in transformer oil when exposed to strong electric fields?

A)Dielectric barrier discharge✓

B)Resonant field amplification

C)Magnetostrictive hysteresis

D)Superconducting flux pinning

💡 Explanation

Dielectric barrier discharge accelerates oil degradation, forming oxidizing free radicals because the electric field exceeds the oil's dielectric strength, initiating partial discharges. Therefore dielectric breakdown occurs, rather than magnetostrictive effects under magnetic fields.
