← TechnologyWhich risk increases when a high-voltage three-phase transformer lacks breaker coordination?
A)Sympathetic trip of upstream breakers✓
B)Transformer core saturation increases rapidly
C)Increased transmission line corona discharge
D)Elevated circulating current within windings
💡 Explanation
Sympathetic tripping becomes more likely because lacking coordination causes cascading breaker failures in the distribution grid during faults; therefore, outages spread dramatically, rather than being confined by properly sequenced breaker operations upstream.
