← TechnologyWhich consequence results when rapid temperature increases in a transformer's oil lead to dissolved combustible gas accumulation exceeding breaker trip thresholds?
A)Internal arcing breaker tripping✓
B)Eddy current harmonic mitigation
C)Increased dielectric oil constant
D)Improved core saturation margin
💡 Explanation
Internal arcing breaker tripping occurs because dissolved gases trigger the Buchholz relay; this uses the principle of gas pressure differential causing alarm signals and mechanical breaker operation, therefore protecting the transformer rather than eddy current mitigation, oil changes, or saturation increases.
