← TechnologyWhich risk increases significantly when repetitive, rapid interruptions occur in a high-voltage DC transmission circuit?
A)Capacitor bank dielectric breakdown
B)Transformer core magnetic saturation
C)Transmission line corona discharge
D)Circuit breaker contact wear✓
💡 Explanation
Circuit breaker contact wear increases under repetitive interruption because arc quenching erodes contact material during each operation, therefore the device degrades, needing replacement sooner, rather than capacitor or transformer faults developing unless outside voltage limits.
