Which failure mode worsens because heat increases in a power transformer circuit?

💡 Explanation

Accelerated oil breakdown occurs via pyrolysis because increased heat reduces oil viscosity, triggering increased dielectric stress across solid insulation; therefore, insulation fails rather than maintaining its barrier function, causing further arcing from core saturation or decreased resistance.
