Which risk increases when a high-voltage transformer experiences thermal runaway?

💡 Explanation

Dielectric breakdown risk increases due to thermal runaway causing irreversible damage thermal degradation lowering breakdown voltage limits, because positive feedback increases heat generation; therefore insulation fails rather than enhanced magnetic performance because temperature is above maximum.
