← TechnologyWhich consequence results when exceeding arc flash protection thresholds?
A)Circuit breaker operation faults occur
B)Transformer core saturation increases drastically
C)Insulation material dielectric breakdown results✓
D)Power factor correction exceeds limits
💡 Explanation
When an arc flash incident happens, the immense heat causes rapid dielectric breakdown because atoms become ionized; this is worsened without proper `arc quenching`. Therefore insulation fails dramatically, rather than triggering immediate breaker faults or similar effects in core saturation.
