Which risk increases when a high-voltage transformer's oil level drops below minimum?

💡 Explanation

Accelerated winding insulation degradation occurs because reduced oil exposes windings; increased heat causes oxidation. With lower oil levels, there will be less effective heat dissipation via convection, therefore the insulation degrades more rapidly rather than other potential issues.
